I have a big tub of those here I put a bunch of rotten potatoes in it and covered it where the varmints and chickens couldn't get to it and destroy it but theres a crack in the lid and the top for the flies to come and go its a gross mass of wriggling (nutritious) vermin in there I throw in kitchen scraps ever so often to keep things a stirring and writhing alongLOL

What do you use them for? do you feed them to the chickens? i have a lidded trash can in the chicken yard to throw garbage in and one day I had masses of bugs: dark colored, almost like a short dark centipede type bug. The girls went crazy, so I let them have them and ever since they get excited if I go near that garbage can. Don't know what kind of bug they were.
