Blue bottle flies are great feeder insects for many types of reptiles and amphibians, and especially for predatory insects.
We sell our blue bottle flies in the pupa stage, and you can store them in the fridge until you are ready to feed them to your pets. That way, you don’t have to worry about flies escaping during your feeding sessions.
When stored at room temperature, the pupae will typically hatch in 2 – 4 days. Blue bottle pupae can be stored up to a month in the fridge. However, after storing this way for 3 – 4 weeks, hatching rates will naturally decline, but you may still get some. We recommend buying more pupae every three weeks to ensure maximum hatch rates.
