Many homeowners use outdoor lighting as a deterrent to keep wild animals like raccoons, skunks and possums away from their home. And, for a short period of time, the lighting does work. But as wild animals get acclimated to their surroundings, they quickly get used to the lighting. To prevent wildlife from rummaging around our homes, the best approach is to keep food sources away. Clamp down trash can lids, and place recycling bins out in the morning. And if you do use lighting, go with the motion-sensing kind. The sudden flood of light can still be enough to warn wild animals to stay away.
