Bulk Superworms: How to Buy, Store, and Save on the Ultimate High-Energy Feeder

If you keep multiple reptiles, a backyard flock, or a busy feeding station, buying superworms one tub at a time gets expensive fast. Bulk superworms solve that — the per-worm cost drops sharply, and with the right storage they stay healthy for weeks. Here is how to buy in bulk, keep them alive, and get the most value out of every order.

What Are Superworms?

Superworms are the larvae of the darkling beetle Zophobas morio. They are larger than mealworms and have a high fat , moisture, and protein content that makes them an energy-rich feeder. Their size and movement make them irresistible to larger reptiles, and their hardiness makes them one of the easiest feeders to keep in quantity.

Why Buy Superworms in Bulk

The main reason is cost. Bought by the bulk box of 500, 1,000, or more, the per-worm price is a fraction of small retail tubs. Bulk buying also means fewer reorders and shipping charges, and a steady on-hand supply so you are never caught short at feeding time. For anyone feeding several animals, the savings add up quickly.

How to Store Bulk Superworms

The single most important storage rule: do not refrigerate superworms. Unlike mealworms, superworms should not be refrigerated. Prolonged exposure to cold temperatures can kill them or significantly reduce their viability. Keep them instead at room temperature, around 70 to 80 degrees Fahrenheit, in a ventilated container.

Give them an inch or two of bedding such as wheat bran or oats, which doubles as food. Add a moisture source like carrot, potato, or sweet potato slices for hydration, and refresh it every couple of days to prevent mold. Under appropriate conditions, superworms can remain viable for several weeks, although exact shelf life depends on temperature, ventilation, stocking density, and food/moisture management.

Gut Loading for Better Nutrition

Gut-loading can improve the nutritional value of feeder insects before they are offered to an animal. Feed superworms a nutritious diet for 24 to 48 hours before feeding, using appropriate vegetables, leafy greens, and a quality grain-based diet. This loads the worms with vitamins and minerals that pass to your reptile, turning a fatty feeder into a more complete one.

Who Eats Superworms

Superworms are a favorite of bearded dragons, larger geckos, monitors, turtles, and other sizable reptiles. They are also relished by backyard chickens as a high-energy treat and by wild birds such as bluebirds. Because they are high in fat, superworms are best used as part of a varied feeder rotation rather than a sole staple, especially for animals prone to weight gain.

Fluker Farms has raised feeder insects in Louisiana since 1956, and our bulk superworms are bred for size and consistency so you get reliable feeders in every box.

Frequently Asked Questions

How long do bulk superworms last?

Stored at room temperature with bedding and a moisture source, superworms stay healthy for several weeks. Never refrigerate them.

How many superworms should I order in bulk?

Match the order to how fast you feed them out so they stay fresh — most keepers buy a few weeks' supply at a time. Boxes of 500 to 1,000 are common bulk sizes.

Can I feed superworms as a staple?

They are high in fat, so they are best as part of a rotation with crickets, dubia roaches, or other feeders rather than the only food, particularly for animals prone to obesity.

Do superworms need to be gut loaded?

Gut loading for 24 to 48 hours before feeding significantly improves their nutritional value and is strongly recommended.

The Bottom Line

Buying superworms in bulk is the most economical way to feed larger reptiles, chickens, and wild birds a high-energy treat. Keep them at room temperature, never in the fridge, give them bedding and a moisture source, and gut load before feeding for the best nutrition.
