I have two L4 praying mantids and one L5 praying mantis. They seem to be outgrowing the D. Hydei flies I have. What would the next logical food source be? Blue bottle flies?
that's the best way of doing it if u dont want flies escaping. Keep the pupae in the refrigerator if you dont want them to hatch. Dont put too many in, just put in 2 or 3 depending on how often ur planning on feeding.
