Where to Buy Waxworms (Expos and Beyond): A Keeper's Sourcing and Care Guide

"Do local reptile expos sell waxworms?" Short answer: yes, nearly always. But that question usually comes from a keeper who really wants to know two things — where to reliably get healthy waxworms, and how to use them without messing up their animal's diet. So this is the full sourcing-and-care guide: what waxworms are, where to buy them (expos and the better alternatives), how to tell a good cup from a bad one, how to store them (there's a refrigeration trap here too), and how to feed this fatty little treat responsibly.

What waxworms are

Waxworms are the larvae of the greater wax moth, Galleria mellonella — small, soft, creamy-white caterpillars, plump and a bit waxy-looking, which is where the name comes from (in the wild they live in and eat beeswax inside honeybee hives). They're prized as a feeder for one reason above all: animals love them. The soft body and sweet, fatty taste make waxworms intensely palatable, which makes them one of the best tools in the hobby for tempting a reluctant eater.

That palatability comes from their defining nutritional feature: waxworms are very high in fat (roughly 20% or more as-fed) and correspondingly low in protein and calcium. They are, in plain terms, the junk food of the feeder world — fantastic in small, deliberate doses, harmful as a staple.

Where waxworms shine (and where they don't)

Use waxworms on purpose, for specific jobs:

• ◆Fattening up an underweight animal — a thin, recovering, or post-illness reptile that needs calories fast.
• ◆Supporting a gravid female or an animal heading into brumation with extra energy demands.
• ◆Tempting a picky or stressed eater — the classic use. The wriggle and the taste pull animals off a hunger strike when nothing else works.
• ◆Occasional variety and enrichment in an otherwise lean diet.

Where they fail is as a regular feeder. Over-rely on waxworms and you get obesity, poor nutrition, and the dreaded "waxworm addict" — an animal that learns to refuse its leaner staple food while holding out for the candy. The discipline is simple: a few waxworms now and then, with a reason, on top of a diet built on roaches, crickets, or other lean feeders.

Where to buy waxworms

Reptile expos

Reptile expos are a great place to buy waxworms. Feeder vendors are a fixture at these events, and waxworms are among the most commonly stocked items. Advantages:

• ◆Inspect before you buy. You can look at the actual cup and judge quality on the spot.
• ◆Bulk options. Vendors often sell from small counts (25–50) up to tubs of 250+, frequently at competitive prices.
• ◆Ask the seller directly. A good vendor will tell you how the worms are kept and how recently they came in.

Practical tips: bring cash (not every vendor takes cards), factor in the entry fee when judging whether a small purchase is actually a saving, and bring a small insulated container so the worms don't cook in a hot car on the way home. Smaller local expos may have a thinner selection than big ones, so call ahead if waxworms are your main goal.

A dedicated feeder supplier

For consistent quality and convenience — especially if you don't have an expo coming up — a specialist feeder supplier is the most reliable route, whether you pick up locally or have them shipped. A good supplier keeps the worms at the right temperature and stage and packs them to arrive plump and alive. All Angles Creatures stocks healthy waxworms sized and cared for as feeders, which takes the guesswork out.

Local reptile shops

A good independent reptile or exotic-pet shop usually carries waxworms and is handy for small quantities. As always, inspect the cup before paying.

A note on bait shops: waxworms are sold as fishing bait, and they're sometimes cheaper there — but bait worms may have been treated or exposed to chemicals you don't want near your reptile. If you go that route, confirm they're untreated before feeding.

How to judge waxworm quality

Whether you're at an expo table or opening a shipped cup, the markers are the same:

• ◆Color. Healthy waxworms are creamy white to slightly yellow. Avoid worms with dark spots, gray discoloration, or any that have turned brown/black (those are dead or dying).
• ◆Plumpness. You want full, firm worms — not shriveled, dried out, or deflated.
• ◆Movement. Give the cup a gentle nudge; healthy worms wriggle. Sluggish, unresponsive worms are on the decline.
• ◆Smell. A good cup has little to no odor. A strong, foul smell means mold, rot, or fouled bedding — walk away.
• ◆Clean, dry bedding. The substrate (usually wood shavings, sawdust, or bran) should be dry and clean, not damp, moldy, or full of dead worms.
• ◆Stage. Ask how old they are. Older worms may be close to pupating into moths, which makes them less useful. Younger, mid-sized worms are ideal.

If a vendor is happy to answer how the worms are fed and stored, that openness is itself a good sign.

Storing waxworms

Storage is straightforward but has the same trap as several other feeders:

• ◆Keep them cool: around 55–60°F. Cool temperatures slow their metabolism and delay them turning into moths, so they hold at usable size and stay alive longer. A basement, cool closet, or wine fridge works well.
• ◆Do not stick them in the coldest part of the refrigerator. Excessive cold kills waxworms — the same mistake that kills hornworms and superworms. Cool, not frigid.
• ◆Keep the bedding dry. Moisture is the enemy; damp or moldy bedding will spoil the cup. If it gets wet, replace it.
• ◆Ventilate. Use a container with a breathable lid so they don't suffocate, but keep them secure.
• ◆Don't overcrowd. If you bought a big batch, split it across cups to reduce moisture and crowding.
• ◆Remove casualties. Pull dead or darkened worms so they don't foul the rest.

Waxworms carry enough fat reserves to survive weeks without feeding. If you want to extend their life or condition them, a little bran or a touch of honey works, but go easy — overfeeding just adds moisture and waste.

Feeding waxworms off

• ◆Treat, not staple — always. A few at a time, occasionally, for a reason. This is the one rule that matters most.
• ◆Size to the animal — no larger than the space between the eyes, as with any feeder.
• ◆Feed live and fresh for the best feeding response; the movement is half the appeal.
• ◆Dust with calcium when appropriate. Waxworms are low in calcium, so a calcium dusting helps offset what is otherwise a poor mineral profile — though you should still be getting most of your calcium and protein from the staple diet.
• ◆Don't let it become a habit. If your animal starts refusing its regular food, cut the waxworms back to break the addiction.

Used this way, waxworms are a genuinely valuable tool — the thing you reach for when an animal is thin, recovering, gravid, or stubbornly off its food. They just aren't the everyday meal.

For the broader nutrition and metabolic-bone-disease picture that explains why a low-calcium, high-fat feeder has to stay occasional, the Merck Veterinary Manual's reptile nutrition section is a reliable, non-commercial reference.
