Squirrels can be a real nuisance, especially if you have more than just one or two hanging around the yard. They have a tendency to dig holes in your lawn and flower beds either hiding food in the fall, or looking for food in the winter and early spring. Unfortunately, there's no easy way of ridding your lawn of the pests, except for eliminating whatever their food source happens to be, which is probably a neighbor that overfeeds or improperly feeds the local bird population.
In early fall, make certain that all possible entry points into your house are tightly secured to prevent them from over-wintering in your home. Squirrels have a tendency to pry open the screen in older gable ventilators. Once inside they can do all sorts of damage including chewing through electrical cables. If you have a squirrel in your attic in the fall, you can count on having a number of baby squirrels in your house come spring.
