Poisoning Squirrels

Rat poison is very lethal and there are restrictions and guidelines for its use.  Rat poison does not only kill rats but everything that injests it including dogs, cats, squirrels, birds that eat squirrels, raccoons, skunks, deer, songbirds, and anything else that might injest the pellets.  Your best bet for killing unwanted squirrels would be to live trap them and euthanize, then properly dispose of them.  Fox squirrels are the big reddish ones found in town and they are not protected.  However, placing rat poison anywhere that is not closely monitored and restricted will lead to unwanted mortality of protected species and neighbors pets, and that is illegal.
