All my crickets died :(

[spec]

I'm thinking i didnt wash the carrots i fed them off and maybe there was pesticides on them. lost about 30 of them, I had even started giving them more heat bigger enviornment all kinds of stuff. With that being said i've made alot of changes in the way i've been keeping them, so i really dont know what caused this. Any other suggestions?

Try a different food source and see what happens.

What size were they? Is your source infected with CrPV?
