Squirrels can become a nuisance both indoors and outdoors. Outside, they terrorize your gardens, trees, and even bird feeders while in search of food. Inside, they can chew through wires and insulation. If you’ve got a squirrel problem in your attic, they will invite their friends and then they will chew through soffit and facia to get into your home. As if this is not enough of a nuisance, they will also chew right through your ceilings or walls as entry to inside your living space.
