Lots of dirt. The only ones I have ever found had made huge underground burrows/hives.has anyone ever had a captive bumble bee colony? if so how does one make one?
You can buy Mantid sacs at some farm supply store, that would be awesome to get one, hatch it, then release the million babies under your porch.i thought the males cant sting because the stinger is a modified ovapositer. Im not sure if the queen/foundress can sting, ive heard conflicting info on them. probably your best bet is to release a few large mantids, or just use the back door. Then you can invite your enemies over and release your swarm upon them, mwahahaagood luck with your bumbles
