Read about the Breeding of Firebrats (Thermobia domestica)
Firebrats pose no danger to your fosterlings and their soft body makes them a tasty and easily digestible treat for all amphibians, mantids, scorpions, tarantulas, jumping spiders and reptiles. Also due to their body size of up to 12 mm they are a perfect link between feeding Drosophila hydei and goldflies. They can survive for weeks in the terrarium and can therefore also be fed on stock. For me personally, oven fish, after Drosophilas, are one of my main food animals.
