Spiders and insects are attracted to homes because bricks, wood siding, landscaping timbers, mulch beds, and wood piles imitate the natural areas they seek out to avoid freezing. Lights, warm surfaces and warm air currents coming from homes are also highly attractive to many insects late in the fall.

These insects can contaminate food and eating utensils, destroy fabric and paper products and impart stains and odors to surfaces they contact.

Although many bugs rarely breed indoors, once you have a colony, proper sanitation alone will not rid the premises of the infestation.
