Begin by identifying the spider involved. Locate where the spiders live and what contributing conditions support the infestation. Remove all potential hiding places inside and outside buildings and improve storage practices. All exterior areas of a building must be secured to eliminate spiders' entrance.

Insecticides may be used as needed according to label directions on the harmful spiders, their webs and on grounds immediately outside infested buildings. For all products, read and follow label directions.

Start insecticide applications by spot treatment of exposed spiders, typically with a spray product, or with a dust product.

If necessary to treat webs apply dust or liquid insecticides that will leave a residual amount of product to deter rebuilding of webs.

To treat perimeter grounds outside infested buildings, direct hand held pressure sprays or "back pack" sprays are generally the product types used.
