As temperatures dip, insects like spiders will be searching for warmer places to call home. One simple and chemical-free way to keep spiders outside your home is to not use outdoor lights. Outdoor lighting does not attract spiders, but it does attract other insects that spiders find appealing as food sources. Spiders will go wherever food is, and a flurry of insect activity near light sources draws them close to your home. At night, pull shades and blinds down to block indoor light. If you must have outdoor lights on, consider using yellow-coated light bulbs; they attract fewer insects and still provide substantial illumination.
