Spider Control

Giant House Spider

An effective approach to spider control is the knowledge of their predatory nature; they primarily consume other insects. So, reducing other insects around the home will lessen their interest in hanging around. Routine, thorough house cleaning is the best way to eliminate spiders and discourage their return. A vacuum cleaner or broom will effectively remove spiders, webs, and egg sacs.

Spiders prefer quiet, undisturbed areas such as closets, garages, basements, and attics. Reducing clutter in these areas makes them less attractive to spiders. Large numbers often congregate outdoors around the perimeter of structures. Migration indoors can be reduced by moving firewood, building materials, and debris away from the foundation. Install tight-fitting window screens and door sweeps to exclude spiders and other insects. Inspect and clean behind outdoor window shutters. Consider installing yellow or sodium vapor light bulbs at outside entrances. Insecticides can be applied as a "barrier treatment" around the base of the foundation. Pay particular attention to door thresholds, garage and crawl space entrances, including foundation vents. Carbaryl, bendiocarb, chlorpyrifos, or any of the synthetic pyrethroids are effective, but may need to be reapplied periodically throughout the summer. Wettable powder or microencapsulated ("slow-release") formulations are most effective.
