Where to Buy Waxworms: A Keeper's Guide to Sourcing, Storing, and Feeding Them Right

Waxworms are one of the most useful feeders in the hobby and one of the most misused. They're the little creamy-white grubs every reptile seems to lose its mind over — soft, fatty, irresistible — which makes them a fantastic tool and a genuinely easy way to wreck an animal's diet if you treat them like a staple.

I've used waxworms for years for exactly the jobs they're good at: putting weight on a thin animal, tempting a sick or stressed feeder back onto food, hiding medication, and as the occasional treat that makes a picky eater enthusiastic again. This guide covers two things people always ask about: where to actually buy good waxworms (the local-pet-store-vs-online question), and just as important, how to store and feed them correctly so they stay alive, don't all turn into moths in a week, and don't quietly make your reptile fat.

Let me start with what a waxworm actually is, because almost every storage and feeding mistake traces back to not understanding the bug.

What a waxworm actually is

A waxworm is not a worm at all. It's the larva of the greater wax moth, Galleria mellonella — a moth whose caterpillars naturally live inside honeybee hives, where they tunnel through and eat beeswax, honey, and hive debris. (To beekeepers, they're a notorious pest; to reptile keepers, they're a feeder.) That wax-and-honey diet is exactly why the larvae are so soft and so fatty, and why they smell faintly sweet.

Understanding the life cycle is the key to everything else in this guide, because waxworms don't just sit there waiting to be eaten. They're one stage of a four-stage insect: egg → larva (the waxworm you feed) → pupa (a silk cocoon) → adult moth. Left at room temperature, a tub of plump waxworms will start spinning cocoons within days and emerge as drab gray-brown moths within a couple of weeks. That isn't a defect — it's the animal doing what it's built to do. Your whole job in storing them is slowing that clock down, which I'll get to in detail below. For background on the species and its biology, the University of Florida's Featured Creatures profile of the greater wax moth is a good non-commercial reference.

Nutrition: why waxworms are a treat, not a staple

This is the single most important thing to internalize, so I'll be blunt: waxworms are candy. They're a high-fat, calorie-dense feeder with modest protein and poor mineral balance. Approximate as-fed figures put them around:

• ◆Fat: very high, ~20–25%. This is the headline. Waxworms are one of the fattiest common feeders, which is exactly what makes them great for weight gain and terrible as a daily food.
• ◆Protein: modest, ~14–16%. Lower than staples like discoid roaches or crickets. Not enough to build a diet on.
• ◆Moisture: ~60%.
• ◆Calcium: poor ratio. Like nearly every feeder insect, waxworms are phosphorus-heavy — far more phosphorus than calcium. They are not a calcium source, and feeding them heavily without correction works against bone health.

Put those together and the verdict is clear. Fed as a staple, waxworms cause real problems: obesity, fatty liver disease (hepatic lipidosis), and "waxworm addiction" — animals that have eaten so many they refuse healthier staples and hold out for the fatty treat. I've watched keepers create picky, overweight geckos entirely by overusing waxworms with the best intentions.

So the rule is simple and firm: build the diet on staples — discoid roaches, dubia, crickets, the calcium-positive black soldier fly larvae — and use waxworms as a treat or a tool, a small fraction of the overall diet. For how that staple foundation should look, see my discoid roach keeping and breeding playbook. For the veterinary view on obesity and nutrition in reptiles, the MSD/Merck Veterinary Manual's reptile nutrition section is worth reading.

When waxworms are exactly the right tool

None of that means avoid them — it means use them on purpose. Waxworms genuinely shine for several specific jobs:

• ◆Putting weight on a thin animal. That high fat content is a feature when an animal is underweight, recovering from illness, or rebuilding condition after brumation. A short course of extra waxworms can turn the corner faster than staples alone.
• ◆Tempting a sick, stressed, or off-food animal. Their soft body and sweet smell make them one of the most reliable "I'll-only-eat-this" feeders. When an animal has stopped eating, a wriggling waxworm is often what breaks the strike.
• ◆Hiding medication or supplements. Soft and easy to handle, they're a convenient vehicle for getting a reluctant animal to take something.
• ◆Picky eaters and bonding. Because almost every insectivore loves them, waxworms are excellent for hand-feeding, building trust with a new animal, or adding occasional variety and enrichment.
• ◆Animals with weak jaws or small mouths. The soft, low-chitin body is gentle for juveniles, smaller species, and animals that struggle with hard-shelled prey.

The common thread: waxworms are a targeted intervention, not a default. Reach for them with a reason.

Waxworms vs. the other treat feeders

Waxworms aren't the only "treat" feeder, and knowing where they sit helps you reach for the right tool. Here's how the common soft/treat feeders compare — approximate as-fed figures, relationships are what matter:

The practical reads:

• ◆Waxworms and butterworms are the "calorie bombs" — reach for them when you specifically want fat (weight gain, recovery, breaking a food strike).
• ◆Hornworms are the opposite tool — nearly fat-free and mostly water, so they're the treat to use when you don't want to add weight, or when an animal needs hydration.
• ◆Silkworms are arguably the best-balanced soft treat — softer profile, more reasonable fat, easy to digest — if you can get them.

So "which treat?" depends on the job. Need to fatten or tempt? Waxworms. Need a guilt-free treat or hydration? Hornworms or silkworms. This is why I keep waxworms in the rotation but never as the only treat.

Which animals eat waxworms, and how many

Plenty of insectivores and omnivores take waxworms happily — leopard and crested geckos, bearded dragons, chameleons, many frogs and salamanders, turtles, and even insectivorous birds like finches during molting or breeding. The constant across all of them is moderation and sizing (feeder no larger than the space between the animal's eyes for smaller reptiles).

Rough treat-level guidance — adjust down for healthy adults, up briefly for underweight animals under a plan:

• ◆Leopard geckos: about 2–3 as an occasional treat, maybe once a week. Easy to overfeed; they love them.
• ◆Crested geckos: a couple now and then for enrichment on top of a complete diet.
• ◆Bearded dragons: a small handful occasionally for adults; useful for underweight juveniles short-term, but not a regular item given obesity risk.
• ◆Chameleons: a few as a treat or to tempt a fussy eater.
• ◆Frogs, toads, salamanders: a couple every so often, watching body condition closely since amphibians overeat readily.

Whatever the animal, dust the waxworms with calcium before feeding to blunt the phosphorus-heavy ratio, and count them against the day's calories rather than adding them on top.

A closer look by animal

• ◆Leopard geckos are the classic waxworm-addiction case. They adore them, will hold out for them, and put on fat fast. Keep waxworms to a small weekly treat (two or three), build the diet on dusted roaches and crickets, and reserve heavier waxworm use for genuinely underweight or post-illness geckos under a plan.
• ◆Crested geckos get most of their nutrition from a complete powdered diet; waxworms are an occasional live-prey enrichment, a couple at a time, not a dietary pillar.
• ◆Bearded dragons trend toward obesity as adults, so adult beardies rarely need the extra fat — use waxworms sparingly or skip them. Fast-growing or underweight juveniles can take them short-term, sized appropriately and dusted.
• ◆Chameleons often respond to waxworms when they're being fussy or settling into a new home; a few to kick-start feeding is reasonable, then rotate back to gut-loaded staples.
• ◆Frogs, toads, and salamanders overeat readily and the fat adds up quickly, so keep waxworms to an occasional item and watch body condition.
• ◆Insectivorous birds (finches, some softbills) benefit from the energy during molting and breeding, but the same moderation logic applies.

The pattern across every species is identical: small numbers, on purpose, dusted, counted as calories.

Using waxworms for weight gain and recovery

The job waxworms do best is putting condition on an animal that needs it — a rescue that came in thin, a reptile recovering from illness or a parasite treatment, or one that's run down after brumation. Used deliberately, that high fat is exactly the right medicine. A few principles I follow:

• ◆Make it a short, intentional course, not a new normal. Bump waxworms up for a defined period while you watch weight and body condition, then taper back to staples once the animal has recovered. The goal is to fix a deficit, then stop.
• ◆Don't drop the staples. Even during a weight-gain push, keep offering staple feeders and (for omnivores) vegetables so you're rebuilding healthy mass, not just fat, and so the animal doesn't fixate on the treat.
• ◆Weigh, don't guess. A cheap kitchen scale and a weekly weight log tell you far more than eyeballing. You want steady gain, not a sudden spike.
• ◆Loop in a vet for the underlying problem. If an animal is thin because it's sick, waxworms are supportive care, not a cure. Treat the cause.

This is the difference between using waxworms as a tool and using them as a habit. The tool version saves animals; the habit version makes them sick.

How to store waxworms so they last (and stay larvae)

This is where most waxworm money gets wasted, so let's get it right. Your goal in storage is to slow the animal's metabolism and delay pupation without killing it. The lever is temperature.

• ◆Keep them cool: around 50–55°F (10–13°C). This is the sweet spot. Cool enough to dramatically slow their development — so they stay plump larvae for weeks instead of turning into cocoons and moths — but not so cold that you kill or chill-damage them. A wine fridge, a cool basement, or a garage that holds that range works well.
• ◆Mind your refrigerator. A standard fridge is often colder than ideal (typically ~37–40°F), which can stress or kill waxworms over time. If the fridge is your only option, use the warmest spot (a door shelf), keep an eye on them, and don't expect fridge storage to be as forgiving as a true 50–55°F. Never freeze live waxworms — that just kills them.
• ◆Leave them in their bedding. Waxworms ship in a substrate of bran, sawdust, or similar. Keep them in it; it absorbs moisture and gives them something to nestle in. Don't add water — excess moisture causes mold and rot, which is what turns a tub black and slimy.
• ◆Use a breathable container. They need a little air. A container with a vented or mesh lid prevents condensation and suffocation. If yours came in a sealed deli cup, poke a few small air holes.
• ◆Don't store them warm. Room temperature is fine for the day or two before you feed them off, but as a storage strategy it's the fast track to a tub of moths.

Stored properly at 50–55°F, a batch of healthy waxworms commonly stays good for several weeks. Stored warm, you may have cocoons in days. That difference is the whole ballgame, and it's why "where you store them" matters as much as "where you bought them."

A quick word on warming before feeding

Cold waxworms are sluggish. If they come out of storage stiff, let them warm to room temperature for a bit before offering them — a warm, gently wriggling waxworm triggers a reptile's feeding response far better than a cold, motionless one. This is especially helpful when you're using waxworms precisely because they move enticingly.

The pupation problem, and how to handle it

Even with good storage, some waxworms will eventually start spinning silk and forming cocoons. That's normal. A few points:

• ◆Cocoons and moths aren't harmful — they're just no longer the soft larva you wanted. Some animals will still eat the pupae or even the moths, so they're not necessarily waste.
• ◆Don't fight it past its limit. If a batch is mostly turning, feed off the remaining larvae quickly rather than trying to hold them.
• ◆You can let some become moths on purpose if you want to dabble in breeding your own — wax moths will lay eggs and the cycle continues — but for most keepers it's simpler to buy fresh batches sized to what you'll actually use before they turn.

The practical takeaway loops back to buying: don't over-buy. Purchase a quantity you'll feed within a couple of weeks (a bit longer with good cool storage), because the clock is always running.

Breeding your own waxworms

If you go through a lot of waxworms, breeding your own is doable — they're not difficult, just a bit smelly and silk-prone. The short version, building on the life cycle we covered:

• ◆Let some larvae pupate and emerge as moths. Keep a portion of a batch warm (room temperature or a little above) in a container the moths can't chew out of — they'll cocoon and emerge as adult greater wax moths.
• ◆Give the moths somewhere to lay. Adults don't really feed; they mate and lay eggs, often in folds of wax paper or on a substrate you provide.
• ◆Feed the new larvae. Hatchling waxworms eat a high-energy medium — classic homemade mixes are based on bran/cereal with honey and glycerin — which is exactly the rich diet that makes them so fatty.
• ◆Harvest larvae before they pupate, holding your feeding stock cool at 50–55°F as always.

Two honest cautions. First, a wax moth culture is a wax-and-honey-eating insect colony — it can smell, attract pests, and the moths will escape if you're careless, so contain it well away from any beekeeping equipment (they're a serious hive pest). Second, for most keepers feeding a pet or two, breeding isn't worth the hassle versus buying small fresh batches. It pays off mainly if you keep many animals or run a long recovery-feeding program.

Breaking "waxworm addiction"

This deserves its own section because it's the most common waxworm problem I get asked about: an animal — classically a leopard gecko — that has eaten so many waxworms it now refuses crickets, roaches, everything else, holding out for the fatty treat. People panic that the animal is "starving itself."

A healthy adult reptile will not starve itself to death over a few days of standoff. Here's how to reset:

• ◆Stop the waxworms cold. As long as they're available (or offered), the animal has no reason to switch.
• ◆Offer only the staple, appropriately sized and, for movement-driven feeders, alive and wriggling. Many strikes break when the prey moves enticingly.
• ◆Wait it out. A healthy adult can comfortably skip meals for several days. Keep offering the staple every day or two and remove uneaten feeders.
• ◆Don't blink. Most resets resolve within a week or two. Caving and offering "just one waxworm" restarts the clock.
• ◆Know when to escalate. Juveniles, very small species, and already-thin or unwell animals have far less margin — for them, or for a prolonged strike in any animal, talk to a reptile vet rather than waiting indefinitely.

The cleanest cure, of course, is prevention: keep waxworms a small treat from the start and you never have to run this gauntlet.

Local pet store vs. online: the honest comparison

Now the question in the title. Both channels can get you good waxworms; they just trade off differently. Here's how I actually weigh them.

A few real-world notes behind that table:

Local stores win on immediacy and inspection. If your gecko is off food tonight, you can drive over, eyeball the tub for plump, active, cream-colored worms, buy 25, and be home in twenty minutes. The catch is that a slow-turnover store may have a tub that's been sitting too warm or too long — which is exactly why being able to inspect matters. Look before you buy, and don't be shy about asking how recently they came in. Bait shops and fishing-supply stores often carry waxworms too, since anglers use them — sometimes fresher than a general pet store, sometimes kept in worse conditions, so apply the same eyeball test.

Online suppliers win on selection, price at volume, and — when you pick a good one — consistency. A feeder specialist that ships waxworms all day knows how to pack them, often guarantees live arrival, and can sell you the right quantity (including small counts, not just bulk) for less per worm. The trade-offs are shipping cost, a day or two of lead time, and the reality that live insects in transit are at the mercy of weather and couriers. Reputable sellers manage this with insulation and seasonal heat or cold packs and stand behind it with a replacement guarantee — which is the thing to actually look for.

My rule of thumb: buy small and local when you need a few right now and can inspect them; buy from a trusted online specialist when you want a known-good quantity, better per-worm value, or a recurring supply. And whichever you choose, judge the seller on the condition of the worms, not just the sticker price — a cheap tub of half-dead waxworms is the most expensive way to buy them.

For waxworms specifically, you can order them from All Angles Creatures, which ships them sized and packed for live arrival so you're starting with a healthy, plump batch rather than gambling on whatever's been sitting in a bin.

How to judge waxworm quality

Whether you're standing at a store cooler or opening a shipping box, the inspection is the same. Healthy waxworms are:

• ◆Plump and firm, not shriveled, deflated, or dried out.
• ◆Creamy white to pale yellow in color.
• ◆Gently active when warmed — a little wriggle is good.
• ◆Clean-smelling (faintly sweet at most).

Warning signs of a bad batch:

• ◆Dark, blackened, or discolored worms — dead or dying.
• ◆Slimy texture or a sour, rotten smell — decomposition, usually from too much moisture.
• ◆Mostly cocoons or moths — old stock that's already turned.
• ◆Liquid pooling in the substrate — moisture problem; rot is coming.

A little silk webbing in the tub is normal and not a problem. A tub that's mostly web, mold, dead worms, or liquid is a hard pass. If an online order arrives in that state, that's exactly what the live-arrival guarantee is for — photograph it and contact the seller.

Shipping and temperature: making live delivery work

If you order online, temperature in transit is the whole risk, and a little planning removes most of it:

• ◆Mind the season. Extreme summer heat and deep winter cold are the danger windows. Good suppliers add heat packs in winter and sometimes cool packs or insulation in summer; many will pause or adjust shipping during genuine temperature extremes.
• ◆Be there for delivery. A box of live insects baking on a porch all afternoon, or freezing overnight, defeats every precaution. Time orders so you can bring them in promptly, or ship to where you can.
• ◆Open and assess immediately. Check condition on arrival, get them into proper 50–55°F storage, and file any live-arrival claim quickly — guarantees usually have a short window.
• ◆Pick faster shipping when it's marginal. In iffy weather, paying for quicker transit is cheaper than replacing a dead batch.

Buy locally and you skip all of this — which, in brutal weather, is a legitimate reason to choose the store even at a higher per-worm price.

Price and quantity: buy what you'll use

Because waxworms are a treat fed in small numbers and have a built-in expiration (pupation), bulk buying often isn't the bargain it looks like. The per-worm price drops with volume, but a tub of 500 doesn't help if you feed three a week and the rest turn into moths or die in storage.

A sensible approach:

• ◆Match the quantity to your real use over a couple of weeks. For most single-pet keepers, that's a small tub, not a bulk order.
• ◆Bulk and subscriptions make sense if you keep many animals, run a recovery feeding plan, or breed your own and want a steady supply — and if you have true 50–55°F storage to hold them.
• ◆Factor shipping into the comparison. A cheap per-worm price plus expedited live shipping can erase the savings over a local tub.

The cheapest waxworm is the one your animal actually eats while it's still healthy — not the one that pupated in your fridge.

Storage troubleshooting

Even with the right setup, storage hiccups happen. Quick fixes:

• ◆Worms turning dark or black: dying or dead. Usually too cold (deep fridge or a cold snap in the garage), too old, or too wet. Salvage the healthy pale ones, discard the rest, and adjust your storage temperature toward 50–55°F.
• ◆Mold or a sour smell: too much moisture. Never add water; if the bedding is damp, the container is the problem — switch to something breathable and discard spoiled bedding and worms.
• ◆Lots of webbing and cocoons fast: too warm. They're pupating. Move them cooler immediately and feed off the remaining larvae quickly.
• ◆Worms shriveled and dry: too dry or too old. A tiny bit of fresh, dry bran can help, but mostly this means the batch is past its prime — use them up.
• ◆Condensation on the lid: poor airflow. Vent the container; trapped humidity leads straight to mold and rot.

The two failure modes are basically "too warm" (they turn into moths) and "too cold/too wet" (they die and rot). Aim for cool, dry, and breathable and you avoid both.

Buying by season

Because waxworms ship live, the calendar matters more than for shelf-stable supplies:

• ◆Spring and fall are the easy windows — moderate temperatures mean low transit risk and the most forgiving shipping. Stock up then if you're buying ahead.
• ◆Summer heat is the bigger danger for waxworms than cold; a box in a hot truck or on a sunny porch cooks fast. Look for suppliers who add insulation/cool packs, ship early in the week to avoid weekend warehouse layovers, and be home for delivery.
• ◆Deep winter requires heat packs and, in extreme cold, may mean a supplier delays shipping until it's safe — that's a sign of a careful seller, not a problem. In a hard freeze, the local store starts looking smart.

Whenever the weather is at an extreme, that's the moment a nearby store you can drive to genuinely beats shipping, even at a higher per-worm price.

Hygiene and handling

A couple of small habits keep things clean and safe:

• ◆Wash your hands after handling any feeder insects and their bedding. As with all feeder inverts, basic hygiene avoids the small risk of transferring bacteria.
• ◆Keep storage away from food prep areas — a tub of larvae in a kitchen fridge is fine if sealed and labeled, but most people prefer a dedicated cool spot.
• ◆Don't leave uneaten waxworms loose in the enclosure indefinitely. A waxworm that isn't eaten will eventually pupate; pull leftovers so they don't cocoon in your substrate.

Gut-loading and dusting waxworms

Two quick, honest points:

• ◆Gut-loading is limited. Waxworms barely feed in storage, and you're typically feeding them off within days, so you can't load them up the way you can a roach or cricket. Don't count on them as a vitamin delivery system.
• ◆Dusting still matters. Right before feeding, toss them in a calcium supplement to offset their poor calcium-to-phosphorus ratio. It won't turn candy into a staple, but it blunts the worst of the mineral problem when you do use them.

The mindset: waxworms are for calories and palatability, with a calcium dusting as damage control — not a feeder you lean on for balanced nutrition.

Live vs. canned or dried waxworms

You'll sometimes see waxworms sold canned or freeze-dried, and they have a niche — but understand the trade-off before you choose them over live.

• ◆Live waxworms move, which is the whole point for most reptiles: movement triggers the feeding response, and a wriggling waxworm is often what convinces a fussy or off-food animal to strike. They're also what you want for hand-feeding and bonding. The downside is the storage clock (they pupate) and the shipping risk.
• ◆Canned/freeze-dried waxworms are shelf-stable and convenient — no pupation, no live shipping. But many reptiles ignore motionless prey, so they work best for animals already trained to eat from tongs or a dish, or mixed into food. They're a backup, not a replacement for live when you actually need the enticement.

For the jobs waxworms are best at — tempting a reluctant eater, recovery feeding — live is usually the right call. Keep preserved ones around only if you have an animal that reliably takes non-moving food.

Don't confuse waxworms with mealworms

New keepers mix these up constantly, and they're very different tools. Mealworms are the larvae of darkling beetles — firmer, browner, with a tougher chitinous skin, and a moderate-protein, lower-fat profile that makes them a more staple-leaning feeder (though their hard shell raises some impaction caution for small animals). Waxworms are softer, paler, much fattier moth larvae built for treats and weight gain. If a care sheet says "feed mealworms" and you reach for waxworms, you're feeding candy where a meal was intended — and vice versa. Read the feeder, not just the tub.

Common mistakes to avoid

• ◆Treating them as a staple. The number-one error, and the cause of obesity, fatty liver, and food strikes. Keep them a small fraction of the diet.
• ◆Storing them warm. Guarantees a tub of cocoons and moths. Cool to 50–55°F.
• ◆Freezing live ones or stashing them in a too-cold fridge. Both kill them; the deep fridge slowly, the freezer instantly.
• ◆Adding water to the tub. Causes mold and rot. They get moisture from their bodies and bedding.
• ◆Over-buying. They expire by turning into moths; buy what you'll use.
• ◆Skipping the calcium dusting. Like most feeders, they're phosphorus-heavy.
• ◆Feeding cold, motionless worms and wondering why the animal ignores them — warm them up first.

Signs your animal has had too many

Because overfeeding is the real waxworm danger, it helps to know what "too much" looks like so you can course-correct before it becomes a vet problem:

• ◆Weight creeping up — a thickening body, a tail with no taper (in geckos), or fat pads filling out where they shouldn't.
• ◆Refusing staples — holding out for treats and turning its nose up at roaches or crickets it used to eat.
• ◆Lethargy or reduced activity beyond normal temperature-driven slowdowns.
• ◆Loose or off stools after fatty meals.

If you spot these, pull waxworms entirely for a while, return to a staple-based diet, and reassess over a few weeks. Most early overfeeding reverses with simple diet correction; persistent obesity or signs of fatty liver warrant a reptile-vet visit. The fix is almost always the same boring discipline that prevents the problem in the first place: waxworms as a small, occasional, purposeful treat.

The bottom line

Waxworms are a brilliant feeder when you respect what they are: the fatty larva of the greater wax moth, perfect as a treat, a weight-gain tool, and a way to tempt a reluctant eater — and a slow disaster if you let them become the main diet. Build the diet on staples, use waxworms on purpose, dust with calcium, and store them cool at 50–55°F so they stay plump larvae instead of racing to become moths.

On the buying question: there's no single right answer, only the right answer for your situation. Buy a small batch locally when you need it now and can inspect it; order from a trusted online specialist when you want better per-worm value, a wider selection, or a recurring supply backed by a live-arrival guarantee. Judge every source on the condition of the worms, and you'll always have a healthy treat on hand for the moments waxworms were made for.
