Terrified yet? You don’t have to be. Spiders are beneficial, as they feed on insects. This makes them beneficial in helping manage pests. They are an important biological control of insect pests in gardens, fields, forests, and homes.While a few spiders do pack a poisonous bite, most are harmless.Many people, however, fear spiders, and would like to exterminate them from in and around their home or building. Check the next slide for tips on controlling spiders.

Controlling spiders:Remove wood piles, rocks, compost piles, old boards, and other sheltering sites adjacent to the home or buildingKeep spiders from entering a building by caulking cracks and crevices around the foundationMake sure all screens and doors are sealed tightKeep crawl spaces free of debris and limit boxes and other potential hiding places from basements and other dark storage areasRegularly vacuum or brush spider websEliminate insects that spiders like to prey on

Controlling spiders, cont’d. Occasional spiders can be removed by hand (wear gloves or grasp the spider with a tissue) or with a vacuum. Sticky traps can capture spiders when placed along baseboards or other migration areas. Where spiders and webbing occur in nuisance numbers on the outside of buildings they can be washed off with a forceful jet of water. Reduction of outdoor lighting, or replacing lighting with yellow or sodium vapor lights that are not attractive to insects, can limit spider web building.Dark colored siding seems to be less attractive than white siding to the insects on which spiders feed.
