Our backyard is practically filled with small pests (chipmunks, squirrels, birds, etc) and recently have been using a high powered air rifle to kill some of them. However, yesterday, we killed a Chipmunk and a Squirrel. They were definitely dead, but I checked them this morning and they were completely gone. We don't have any cats or dogs, and we're worrying if we have an even bigger pest lurking in our back yard and starting to worry.
