I killed a 6 foot monster yesterday and now I am freaked out thinking there might be more?!?! I have gone all through Google and get mixed results. Many articles say they travel in pairs? I have researched repellents and there are mixed results. Does anyone have any experience with these fucks? I know beyond a shadow of doubt that my puppy will go right after the damn thing because she is always chasing a black snack that hangs out in my front yard.
