Spiders are beneficial arthropods that are an important biological control, helping to keep unwanted pests in check. Although most spiders are completely harmless, many people are uncomfortable sharing their living environment with the eight-legged creatures, while other people are bothered by the cobwebs that can often be seen in corners. Spiders are especially problematic when they seek shelter as the weather cools in early autumn. Proper sanitation and clean-up of spider habitats is the best and safest way to control indoor spider infestations.
Things You'll Need
Caulk
Feather duster
Vacuum cleaner with hose attachment
Broom or hose with spray nozzle
Yellow light bulbs
Sticky traps
Insecticide
Clear debris around your home. Remove plant debris and large rocks. Move compost piles or wood piles away from your house. Keep weeds under control and mow tall grass. Trim shrubs and other plants adjacent to your house.
Caulk cracks and holes in the walls, foundation and around windows. Check the seal on all doors and screen doors, and repair them if necessary. Keep basements, crawl spaces and other dark areas clear of newspapers and cardboard boxes.
Remove spiderwebs inside your house with a feather duster or vacuum with hose attachment. Sweep spiderwebs from the outside of your house, or remove them with a hose and spray nozzle.
Install yellow light bulbs in outdoor light fixtures. Yellow bulbs won't attract the insects that spiders feed on.
Place sticky traps along baseboards, in storage areas or dark corners. Use sticky traps made for roaches or ants.
Use pesticides if environmental modification fails to control the spiders in your house. Pesticides work best if used in combination with environmental modification. Use a household insecticide labeled for spiders, then apply the insecticide strictly according to the directions on the label. Spray the insecticide in cracks and crevices, behind baseboards and in other hiding places.
Tips & Warnings
Remove spiders from inside your house with a glass jar. Place the jar over the spider. Slip a piece of paper under the jar, then release the spider outdoors.
