Gas?!?!? Just use a claw hammerbobme said:Also please make sure you kill them in a safe way, dont use mouse toxins to kill them, if you can, like i can, i have a N2O tank i can kill them with, trap them and kill them that way. Buy gas, but dont kill them with toxics.

Thanks for the info, FT.
I don't know if I'll ever bring it in practice, but that's besides the point...
