We tried to gas our resident groundhog with those gas things, to no avail. At Home Depot, they have small traps, 2 to a package for less than $5.00 and I think they can be used several times. The first night we put one out, the furry creature was caught, spikes ran right through his little head. As for roasting them???????? ewwwwwwwwwwwwwwwwwwwww!!!!!!
