Springtails in Your House: What They Are, Why They Showed Up, and How to Get Rid of Them

If you've found a scatter of tiny dark specks around your bathroom sink, on the surface of a houseplant's soil, or peppered across a damp windowsill — and those specks jump when you get close — you've almost certainly met springtails. They show up suddenly, often in alarming numbers, and the instinct is to reach for bug spray and assume the worst.

Here's the thing I want to settle right at the top, because it changes everything about how you handle them: springtails are harmless. They don't bite, they don't sting, they don't spread disease, and they cannot damage your house, your food, or your plants in any meaningful way. What they are is a living moisture meter. When springtails appear indoors, they're telling you that some part of your home is wetter than it should be. Fix the water and the springtails leave on their own — usually without a single drop of pesticide.

I keep invertebrates, and I deliberately culture springtails for my bioactive enclosures, where they're one of the most useful little animals you can own. So I come at this from both sides: I know exactly why they're a non-event when they wander into a home, and I also know why a whole hobby pays money to keep them on purpose. This guide covers all of it — what springtails actually are, why they've shown up, how to clear them out the right way, how to keep them from coming back, how to tell them apart from things that do matter, and the surprising flip side where these "pests" become prized helpers.

What springtails actually are

Springtails are members of the class Collembola. The single most common mistake you'll read online — including in plenty of pest-control articles — is calling them insects. They're not, quite. Springtails are hexapods (six-legged arthropods), but they sit in a separate lineage from true insects (class Insecta). The practical differences: springtails have internal mouthparts tucked into a pouch in the head (entognathous), they are never winged at any life stage, and they possess a springing organ that no true insect has. So while it's fine to call them "bugs" at the dinner table, knowing they're Collembola helps you understand why the usual insect-pest playbook doesn't really apply to them.

They're small. Most household springtails run between 1 and 2 millimeters long — well under an eighth of an inch — which is why a cluster of them reads as "dirt that moves." Their bodies are soft and either elongated or rounded depending on the group, and color ranges widely: white, gray, slate, brown, black, and occasionally a faint metallic or iridescent sheen. Up close under a hand lens they're genuinely charming little animals, but at arm's length they just look like specks.

The name comes from their party trick. On the underside of the abdomen, most springtails carry a forked, tail-like appendage called a furcula. At rest it's folded forward and held under tension by a clasp called the retinaculum, like a loaded spring. When the animal is startled, the furcula snaps down against the surface and flings the springtail into the air — several times its own body length, in a fast, erratic, unpredictable hop. It's a pure escape reflex, not directed movement, which is exactly why a disturbed cluster seems to scatter in every direction at once. Not every springtail group has a well-developed furcula (some soil-dwelling species have reduced or lost it), but the jumpers are the ones you'll notice indoors.

What they eat and why they matter outdoors

This is the part that reframes the whole "infestation." Springtails are decomposers. Their diet is mold, fungal hyphae, algae, bacteria, decaying leaf litter, and other rotting organic matter. They do not eat living plant tissue in any significant way, they don't eat wood, they don't eat fabric, and they don't eat your pantry. They eat decay.

Outdoors, that makes them quietly essential. Springtails are among the most abundant arthropods on Earth — a single square meter of healthy forest or grassland soil can hold tens of thousands of them. They graze the fungal and microbial film on decomposing material, break down organic matter, recycle nutrients back into the soil, and even help control certain plant-pathogenic fungi by eating them. A teaspoon of rich garden soil is a thriving springtail metropolis, and the soil is better for it.

So when one wanders into your bathroom, understand what it's looking for: not you, not your food, not your house's structure — just moisture and a film of mold or decay to graze on. That's the entire motivation. Take those two things away and you've solved the problem at the root.

A few anatomy details worth knowing

Two other features of springtail biology are worth a quick mention, because they show up if you ever look at one closely and they explain a lot about the animal's behavior.

The first is the collophore (also called the ventral tube), a small finger-like organ on the underside of the first abdominal segment. It's involved in water and ion regulation and in helping the animal stick to surfaces — and it's a big part of why springtails are so tightly bound to humid environments. They're essentially managing their water balance through their skin and this organ, with very little of the waxy, waterproof cuticle that lets a true insect survive dry conditions. That's the physiological reason a dehumidifier is such an effective weapon against them: you're not poisoning them, you're simply removing the humid microclimate they can't live without.

The second is their eyes. Many springtails have simple eye patches rather than the complex compound eyes of most insects, and some cave- or deep-soil-dwelling species are eyeless entirely. The household species you'll meet generally have enough vision to orient toward light, which is why you'll see them congregate at bright windows — but their world is really governed by moisture and chemistry, not sight.

The life cycle: how a population builds

Springtails develop through what's called ametabolous development — there's no dramatic metamorphosis. Unlike a caterpillar becoming a butterfly, or even a roach nymph slowly transforming, a springtail hatches from its egg looking like a tiny version of the adult and simply grows larger through a series of molts. There's no larval stage, no pupa, no winged adult form. A juvenile springtail is just a small springtail.

That simplicity is part of why populations build so fast. Females lay eggs — singly or in small clusters — in damp substrate, and in warm, humid, food-rich conditions those eggs hatch in a matter of days to a couple of weeks. The young reach reproductive maturity quickly, and unusually for arthropods, springtails keep molting even as adults, often continuing to shed throughout their lives. Generation times are short, individual lifespans run from several weeks to several months depending on species and conditions, and a single damp pocket can sustain overlapping generations continuously.

Put the pieces together and the "sudden infestation" makes biological sense: short egg-to-adult time, no fragile metamorphosis to bottleneck the population, continuous breeding, and a strong tendency to aggregate in the best spots. Give them moisture and food and the numbers compound. Take the moisture away and the same fast life cycle works against them — without humidity, the eggs and soft-bodied juveniles dry out and the population crashes just as quickly as it grew.

Why springtails showed up in your home

Springtails are driven indoors by one master variable: moisture. Their soft bodies have almost no protection against water loss, so they're physiologically chained to humid microclimates. A springtail in dry air dehydrates and dies quickly. That single vulnerability explains every pattern you'll notice about where and when they appear.

Here are the usual triggers, roughly in order of how often I see them blamed:

• ◆A plumbing leak or chronic damp. A dripping trap under a sink, a slow leak behind a wall, condensation pooling on cold pipes, a basement that never quite dries — any persistent water source grows the mold and microbial film springtails eat, and holds the humidity they need. This is the classic indoor source.
• ◆Overwatered houseplants. This is the one people least suspect and most often have. Constantly soggy potting soil grows a surface film of mold and algae that is, to a springtail, a buffet in a perfectly humid box. Indoor plant pots are probably the single most common spot I see people find them.
• ◆A weather swing. During long rainy stretches, outdoor soil gets oversaturated and springtails move toward drier shelter — sometimes that's your foundation and then your home. Paradoxically, a drought does the same thing in reverse: as outdoor soil bakes dry, springtails migrate toward the reliable humidity indoors. Heavy rain followed by a hot spell is a classic mass-appearance trigger.
• ◆Humid, poorly ventilated rooms. Bathrooms without working exhaust fans, closed-up basements, laundry rooms, and crawl spaces all hold the kind of stale, damp air springtails thrive in.
• ◆Decaying organic matter indoors. Damp cardboard, soggy paper, mildewed grout, mold behind a fridge or under a dishwasher, a forgotten wet mop — all of it feeds them.

How they physically get in is almost beside the point, but for completeness: they slip through foundation cracks, gaps around windows and doors, worn weather stripping, and the small openings where pipes and wiring penetrate walls. At 1–2 mm, they need almost nothing. But here's the key insight — a few springtails getting inside is normal and inevitable. They only become a visible problem when the inside is wet enough for them to stay and multiply. A dry house simply isn't habitable for them, no matter how many wander in. That's why sealing cracks is a secondary measure and moisture control is the primary one.

Why it looks like a sudden invasion

Springtails reproduce quickly when conditions are good, and they aggregate — they tend to clump together in the dampest, most food-rich spots rather than spreading evenly. The combination means a population can build up invisibly in a wet, hidden area (the soil of a plant, the gap under a sink, a damp basement corner) and then seem to "appear" overnight when it spills into view or when a humidity spike pushes it into the open. The invasion almost never started the day you noticed it. You're seeing the visible tip of a population that the moisture has been quietly supporting for a while.

How to know it's actually springtails

Before you do anything, confirm what you're dealing with, because the fix is completely different for, say, fleas or fungus gnats. Springtails have a recognizable signature.

Look for these signs:

• ◆Tiny specks that jump. Stationary, they look like flecks of pepper, soot, or dirt — on windowsills, around sinks and tubs, on soil surfaces, near drains. Disturb them and they scatter with that abrupt, random, springing hop. That jump-and-scatter is the giveaway.
• ◆They cluster in or near moisture. Damp bathroom corners, the rim of a sink, overwatered plant pots, basement floors, around leaks. If the specks are somewhere dry, they're probably not springtails.
• ◆They gather near light. You may see clusters at windows, light fixtures, or patio doors, especially in the evening — but always paired with a nearby moisture source.
• ◆They persist through cleaning. Wiping the surface doesn't fix it, because the population is living in the damp crevice or soil nearby, not on the surface you cleaned. Persistence despite cleaning is itself a clue that you haven't found the moisture yet.

Springtails vs. the things people confuse them with

This is where most of the panic comes from, so let me lay it out plainly. The lookalikes — fleas, fungus gnats, mites, ants — each have a tell.

The two most common mix-ups:

• ◆Fleas. Both jump, which is the entire source of the confusion. But fleas are larger, hard-bodied, reddish-brown, bite people and pets leaving itchy red marks, jump in a high directed arc, and live on or near animals. Springtails are soft, smaller, don't bite anything, jump short and randomly, and live near water and decay. If nothing in the house is being bitten and the bugs are clustered around a damp sink rather than on the dog, they're springtails.
• ◆Fungus gnats. If you've got them in a houseplant and they fly, those are fungus gnats, not springtails. Springtails crawl and jump but never fly (no wings, ever). The two often show up together in the same overwatered pot because they like the same conditions — but the fix, happily, is the same too: dry the soil out.

Are springtails harmful? The honest answer

Let me be unambiguous, because there's a lot of fear-mongering out there: springtails are not harmful. Specifically —

• ◆They don't bite or sting. They have no biting mouthparts capable of breaking skin and no stinger. The occasional "springtails are biting me" report almost always traces to something else (often a different pest, or skin irritation from dry air or actual mites), or to the unsettling sensation of one hopping onto skin, which isn't a bite.
• ◆They don't transmit disease. They're not vectors for anything that affects humans or pets.
• ◆They don't damage your home. No eating wood, drywall, insulation, or fabric. They are not termites, carpet beetles, or clothes moths.
• ◆They don't ruin stored food. They're not a pantry pest. They eat decay, not your flour.
• ◆They don't meaningfully harm living plants. In a houseplant, springtails are eating the mold and decaying matter in soggy soil, not the plant. In rare cases of a massive population in seedling trays they may nibble very tender root hairs, but for established plants they're harmless and arguably beneficial soil organisms. The overwatering that drew them is a far bigger threat to the plant than the springtails are.

The only legitimate complaint about springtails is aesthetic and psychological: nobody wants thousands of jumping specks in their bathroom, and the sheer numbers feel like an invasion. That's a real annoyance — I'm not dismissing it. But it's a nuisance, not a hazard. University extension entomologists are unanimous on this point; the University of Minnesota Extension's guide to springtails classifies them as a harmless nuisance pest and likewise points to moisture as both the cause and the cure. And critically, it means you can take your time and solve it correctly (by drying things out) instead of panic-spraying chemicals you don't need.

There's a useful mental reframe here: a springtail outbreak is a free home inspection. They've found moisture you didn't know you had. The leak, the over-watering, the bad ventilation, the hidden mold — those are the actual problems worth caring about, and the springtails just pointed at them for you. Fix what they found and you get a healthier home as a bonus, not just fewer bugs.

How to get rid of springtails indoors

The entire strategy fits in one sentence: take away the water, and the springtails leave. Everything below is in priority order. Do the moisture work first — it's what actually solves the problem. Sprays and powders are secondary, optional, and frankly often unnecessary.

Step 1: Find and fix the moisture (this is 90% of the job)

Walk the damp spots and figure out why they're damp:

• ◆Hunt for leaks. Check under every sink, behind toilets, around tubs and showers, under the dishwasher and fridge, and anywhere you've seen water stains. Fix dripping faucets and leaking traps. A slow leak you've ignored is very often the whole answer.
• ◆Drop the humidity. Run a dehumidifier in basements, crawl spaces, and any chronically damp room. Aim to hold relative humidity below 50% — springtails struggle and populations collapse in that range. A cheap hygrometer tells you where you stand; don't guess.
• ◆Ventilate. Run bathroom exhaust fans during and after every shower, run the range hood when cooking, and open windows when weather allows. Stale humid air is springtail habitat; moving air is not.
• ◆Check the grading and drainage outside. Make sure gutters and downspouts carry water away from the foundation, and that the ground slopes away from the house. Water pooling against the foundation keeps the adjacent indoor areas damp.

Step 2: Deal with overwatered plants

If your springtails are in houseplant soil — extremely common — here's the fix:

• ◆Let the soil dry out. Stop watering and allow the top inch or two of soil to dry completely between waterings. A dried-out surface removes both the humidity and the mold film the springtails are grazing. This alone usually clears them.
• ◆Repot if it's bad. For a heavy population, repot into fresh, well-draining mix and discard the old soggy soil. Make sure the pot actually drains and isn't sitting in a saucer of standing water.
• ◆Bottom-water going forward. Watering from below and letting the surface stay drier makes the pot far less hospitable to both springtails and fungus gnats.

Remember: in a plant, springtails are a symptom of overwatering. The springtails aren't hurting the plant — the chronic sogginess is. Fixing your watering habit solves both.

Step 3: Physically remove the visible ones

While the area dries:

• ◆Vacuum or wipe them up. A quick pass with a vacuum (or a damp paper towel) removes the visible clusters immediately. It's cosmetic — it doesn't fix the cause — but it gives instant relief while the moisture work takes effect.
• ◆Clean off the mold and algae. Scrub mildewed grout, slimy drain edges, and any visible mold with a household cleaner. You're removing their food.

Step 4: Seal entry points (prevention, not cure)

Once things are dry, make it harder for new ones to wander in:

• ◆Caulk and seal cracks in the foundation, around window and door frames, and where pipes and wires enter walls.
• ◆Replace worn weather stripping on doors and windows.
• ◆Keep mulch, leaf litter, and wood piles at least about a foot away from the foundation so the outdoor population isn't living right against the house.

Step 5 (optional): Targeted treatments, only if needed

If — and only if — you've addressed the moisture and still have a stubborn population, you can add a physical or chemical assist. These are supplements to drying out, never substitutes for it:

• ◆Diatomaceous earth (DE). A fine powder of fossilized diatoms (a kind of algae). It works mechanically, abrading and dehydrating soft-bodied arthropods that crawl through it — no poison involved. Lightly dust it along baseboards, thresholds, windowsills, and dry crevices where springtails travel. Use food-grade DE, apply a thin layer (a thick pile does nothing), keep it dry to stay effective, avoid breathing the dust, and reapply after cleaning. Honestly, DE only works on dry surfaces — which tells you again that the real fix is dryness.
• ◆Vinegar solution. Equal parts white vinegar and water in a spray bottle cleans surfaces, removes the mold film, and kills springtails on contact. Good as a cleaner-plus-deterrent on tiles, counters, and baseboards.
• ◆Insecticides — genuinely a last resort. Pyrethroid-based indoor sprays (e.g., bifenthrin or permethrin products) labeled for indoor pests will kill springtails, but I'd urge you to exhaust everything else first. Here's why they so often disappoint: the spray kills the springtails you can see while doing nothing about the damp that will simply grow a new population next week. You end up reapplying poison indefinitely instead of fixing a leak once. If you do use one, read and follow the label exactly, spot-treat only the active areas (baseboards, sills, damp corners — never broadcast-spray), ventilate the space, wear gloves and eye protection, and keep kids and pets off treated surfaces until dry.

The deeper point I want to leave you with on treatment: a chemical that ignores the moisture is treating the smoke and leaving the fire. I've watched people spray for months and stay frustrated, then fix one leak and have the problem vanish in a week.

Room by room: where springtails hide and what to do

Different parts of the house produce springtails for different reasons. The principle is always moisture, but the specific culprit changes by room, so here's how I'd work each one.

Bathrooms

Bathrooms are the single most common indoor springtail spot, because they combine standing water, daily condensation, and grout and caulk that hold moisture and grow a film of mold. Look around the base of the toilet, the edges of the tub and shower, the sink overflow, and the grout lines.

• ◆Find the leak or the lingering damp. Check the toilet's wax seal area, the supply lines, and under the sink. A toilet that sweats or a tub surround that never dries is a steady source.
• ◆Run the exhaust fan during and for 20–30 minutes after every shower. If the fan is weak or missing, that's often the whole problem — a bathroom that can't dry between showers stays springtail-friendly indefinitely.
• ◆Scrub the mold film off grout and caulk; redo failed caulk that's letting water sit behind it.

Basements and crawl spaces

These are the chronic-humidity zones. Cool concrete, poor airflow, and ground moisture wicking through the slab or walls create exactly the stable damp springtails love, and they can build large populations down here unseen.

• ◆Run a dehumidifier continuously if needed, targeting under 50% relative humidity. In a damp basement this is the highest-leverage single move you can make.
• ◆Address ground moisture — check for a working vapor barrier in crawl spaces, fix any water intrusion, and make sure exterior grading and gutters carry water away.
• ◆Clear out damp cardboard, paper, and stored organic clutter, which both feeds them and holds moisture. Switch to sealed plastic bins on shelves off the floor.

Kitchens

In kitchens, springtails gather around the sink, under the cabinet plumbing, behind and beneath the dishwasher and refrigerator, and near drains — anywhere a slow leak or condensation keeps things damp and a little organic film builds up.

• ◆Inspect under the sink and behind appliances for slow leaks and standing condensation; dry and fix what you find.
• ◆Clean drains and the area around them, where a slimy organic film accumulates.
• ◆Wipe up standing water and keep the under-sink cabinet dry; a small leak there is a classic hidden source.

Houseplants

Worth repeating as its own case because it's so common and so often misdiagnosed: if springtails are in the pot, the plant is overwatered. Let the soil dry between waterings, switch to bottom-watering, repot into fresh well-draining mix if the population is heavy, and make sure the pot drains and isn't standing in a saucer of water. (And remember — in the soil they're harmless to an established plant; the sogginess is the real risk.)

Everywhere: the unifying move

Across every room, the pattern is identical — locate the water, remove it, improve airflow, clean off the organic film, and the springtails have nothing to stay for. Caulking cracks and gaps throughout the home is a useful finishing touch, but it's the drying-out that does the work.

When to call a professional

The vast majority of springtail situations are a DIY moisture fix. But there are genuine cases for professional help:

• ◆You can't find the moisture source. If springtails persist and you truly can't locate the damp — it's inside a wall, under a slab, in an inaccessible crawl space — a pest or moisture professional has meters and experience to find it.
• ◆The numbers are overwhelming and persistent despite real moisture work, especially in large homes or commercial buildings where the affected area is extensive.
• ◆There's an underlying problem you need diagnosed — a hidden plumbing failure, a foundation drainage issue, or a serious mold situation. In those cases, frankly, you may want a plumber, a waterproofing contractor, or a mold remediation specialist more than an exterminator, because the springtails are just the messenger.

A good pro will inspect, identify the moisture driver, treat if appropriate, and — most importantly — tell you how to keep the conditions dry so it doesn't recur. Be wary of anyone who wants to spray on a schedule without ever discussing why your home is wet.

How to keep springtails from coming back

Long-term prevention is just permanent moisture discipline. None of this is exotic — it's the same habits that keep a home healthy in general:

Control moisture, permanently.

• ◆Keep relative humidity below ~50% in damp-prone areas; run a dehumidifier where needed.
• ◆Fix leaks promptly — don't let a slow drip become a chronic damp zone.
• ◆Run exhaust fans in bathrooms and kitchens as a habit, not an afterthought.
• ◆Ensure crawl spaces and basements are ventilated and, where appropriate, have a vapor barrier.

Starve them of food.

• ◆Clean up mold and mildew wherever it appears; address recurring mold at its moisture source.
• ◆Don't let damp cardboard, paper, or organic clutter accumulate, especially in basements and garages — store such things dry and elevated, ideally in sealed plastic bins rather than cardboard.
• ◆Sweep and vacuum corners and under appliances where damp detritus collects.

Manage the outdoor perimeter.

• ◆Keep mulch, compost, leaf litter, and firewood away from the foundation.
• ◆Maintain gutters and downspouts; keep water flowing away from the house.
• ◆Don't overwater garden beds and lawn right up against the walls.

Water houseplants correctly.

• ◆Use well-draining soil and pots with drainage holes.
• ◆Let the soil surface dry between waterings.
• ◆Never let pots sit in standing water in their saucers.

Stay a little vigilant.

• ◆Periodically check the usual damp spots — under sinks, basement corners, plant soil — so you catch a moisture problem (and a budding springtail population) early, while it's trivial to fix.

Do these and you don't just prevent springtails — you prevent the mold, wood rot, and air-quality problems that the same dampness causes. The springtails were always the least of it.

The flip side: why hobbyists buy springtails on purpose

Here's where I get to share the part most homeowners never hear, and the reason I personally keep cultures of these animals going at all times. The exact same creature you're trying to evict from your bathroom is, in another context, one of the most valuable little workers in the entire reptile, amphibian, and invertebrate hobby.

In bioactive setups — vivariums and terrariums built to function like a tiny self-sustaining ecosystem rather than a sterile box — springtails are the foundation of the cleanup crew (CUC). The idea is that instead of you tearing the enclosure down to scrub it, a population of detritivores lives in the substrate and does the janitorial work continuously. Springtails are the smallest and most numerous members of that crew, and they earn their keep by:

• ◆Eating mold. This is the headline benefit. Set up a warm, humid enclosure with leaf litter and wood and you will get mold blooms, especially early on. A healthy springtail population grazes mold faster than it can spread, keeping the tank clear without any intervention from you. The very trait that makes them a "moisture indicator" in your home — they go wherever it's damp and there's fungus to eat — is exactly what makes them a self-deploying mold patrol in a vivarium.
• ◆Breaking down waste. They consume animal droppings, shed skin, decaying plant matter, and uneaten food, helping turn it into part of a living, healthy substrate instead of letting it foul the enclosure.
• ◆Feeding the smallest animals. For dart frogs, tiny froglets, small geckos, and other micro-predators, springtails are an ideal live food — small enough for animals that can't tackle anything bigger, and they reproduce fast enough to be a renewable in-tank food source.

Hobbyists culture them deliberately in simple containers — a tub with a layer of horticultural charcoal or moist substrate, kept humid, fed a few grains of yeast or rice or fish flake — and they multiply into the thousands. You scoop out a portion to seed a new enclosure or feed it to animals, and the culture rebounds. It's one of the easiest, most rewarding cultures in the hobby, and a thriving springtail population is a sign of a healthy, well-balanced bioactive setup, not a problem.

The common cultured types you'll see are tropical/white springtails (great for warm, humid setups) and temperate springtails (a bit larger, good for cooler enclosures and as feeders) — selected, vigorous strains rather than whatever wandered in from the yard. If you're building a bioactive vivarium and want a clean, reliable starter culture, you can pick up springtail cultures from All Angles Creatures ready to seed straight into your enclosure's substrate.

So the next time you find them around the house, you can at least appreciate the irony: you're looking at a small population of one of the hobby's most sought-after helpers, doing — in your bathroom — exactly the same mold-and-decay cleanup job that keepers pay to have done in their tanks. The difference is purely context. In a damp bathroom they're a nuisance pointing at a leak. In a well-built vivarium they're an unpaid cleaning staff. Same animal, same diet, same love of moisture.

The short version

Springtails (class Collembola) are tiny, harmless, six-legged decomposers that eat mold and decay and need constant moisture to survive. They don't bite, sting, spread disease, or damage your home, food, or plants. When they appear indoors — in bathrooms, basements, around drains, or in overwatered houseplants — they're not really an infestation so much as a moisture alarm.

The fix follows directly from the biology: dry everything out. Fix leaks, run dehumidifiers and exhaust fans to hold humidity under 50%, let soggy plant soil dry between waterings, clean up mold and damp clutter, and seal cracks to slow re-entry. Do that and the population collapses on its own, usually within days to a couple of weeks — no exterminator, and rarely any pesticide. Reach for diatomaceous earth, vinegar, or, as a true last resort, a labeled indoor insecticide only if a stubborn population survives after the moisture is genuinely handled.

And keep the irony in mind: the same animal you're clearing out of the bathroom is a prized bioactive cleanup-crew worker that hobbyists culture and buy on purpose. Springtails are never really the problem. The water is. Fix the water, and you've fixed the springtails — and a few things you didn't know were wrong with your house, too.
