Spikes for Sale, 50 Count
This is a 50-count pack of spikes, the larvae of the blue bottle fly, about 1/4″ to 1/2″. The small count is the low-cost way to try spikes for one or two animals, or to offer an occasional treat without buying a large amount. Reptiles, dart frogs, and other insectivores take them, and they work as fishing bait too.
Feed as Larvae or Flies
Spikes give you two options. Feed the crawling larvae as they arrive, or let the batch pupate and emerge as blue bottle flies. The flies make a lively treat that chameleons and other hunters chase around the enclosure.
Dust for Calcium
Like most feeders, spikes are low in calcium, so dust them with TC Calcium Ultra Fine before feeding. They are not the same as calcium-rich black soldier fly larvae, so offer them as variety rather than a staple.
Care
Refrigerate spikes as soon as they arrive, between 33 and 39°F, so they stay as larvae instead of turning into flies. Kept cold, they last for weeks. For all larvae and no pupae, order overnight shipping with a cold pack. Warm the batch when you want flies.
