Have no idea. Caught one who happened to get into my old bag of dirt i had bought to grow seeds in dirt (but ditched cuz the hydroponic ones worked out better). I thought, well you little bastard, if youre gonna live on a bed of dirt ment for herb then youre gonna experience some with me. I put him in a plastic snap shut box that i got some blueberry muffins in the other day. tapped it shut with 2 strays for vents. been blowin my smoke in there alot foggin shit up. It freaked him out the first time. He just accepts it now....after like 2-3 hours of this. Im pretty baked, i hope he is too.
