About This Product

Unit quantities are measured by weight. 8 ounce cups contain about 500 blue bottle fly larvae (worms or pupated)!

Blue Bottle Fly Spikes (Calliphora vomitoria) are a great way to add some variety to an exotic pet's diet, and make a nutritious feeder insect. Blue Bottle Fly Spikes are about 1/4-1/2 inch in length when sold. Blue Bottle Fly Spikes are great options for reptiles such as leopard geckos, crested geckos, fat tailed geckos, bearded dragons, chameleons and many other reptiles, amphibians, birds, fish, and invertebrates. Wild birds love Blue Bottle Fly Spikes! If you are looking for a quality, low fat source of protein and calcium for your pet Blue Bottle Fly Spikes are a great option for you!

How to Feed: Blue Bottle Fly Spikes can be fed using a feeding dish or feeding tongs. Offer as many Blue Bottle Fly Spikes as your pet can consume in 5 minutes. Any escapee Blue Bottle Fly Spikes may burrow into the substrate and pupate.

Blue Bottle Fly Spikes can also be pupated and allowed to become blue metallic flies similar in size to house flies. To pupate Blue Bottle Fly Spikes, leave the larvae in a larger container at room temperature for a few days. If the substrate apears to be dry add enough water to make it slightly damp. Flies can be given to chameleons, tree frogs, anoles, and other exotic pets as enrichment - a mentally stimulating addition to a nutritious diet! Place the adult Blue Bottle Flies in the fridge for several minutes to slow them down, making moving them into your pet's enclosure easier.

How to Store: Blue Bottle Fly Spikes should be kept in the fridge as they do well in temperatures between 33° and 40°F. Keep spikes stored on the damp sawdust they're packaged in for a longer shelf life.

Please note: because of elevated temperatures during shipping, your blue bottle fly spikes may arrive pupated! In this case, either store the pupae in the fridge until you're ready to hatch them out into flies, or leave them at room temperature and you'll have blue bottle flies ready to feed out in 2-4 days.

We also carry a huge variety of feeder insects, shipped right to your door for an everyday low price!
