Spiders are easy to kill and very tricky to keep out. First let us look at some details about them.
- There are about 1000 species of spiders in the United States. They live everywhere, even inside homes and buildings. The brown recluse and the widow spiders are considered venomous spiders; however, most spiders are not harmful to man.
- Spiders feed entirely on living insects or other animals, they may actively search for their prey, hide and wait for them to pass, or build webs to trap flying insects.
Control:
Non-Chemical Control of Spiders
Outside lights should not be left on at night. Trash, lumber piles, bricks, weeds, and outside structures are good breeding places for spiders and should be cleaned up. Inside the home spider webs should be brushed down. The egg sacs should be destroyed, vacuum cleaner attachments may be used to clean walls, and the collected debris should be destroyed.
Chemical Control of Spiders
Chemical control of spiders is difficult outdoors because web spinning spiders do not tend to contact treated surfaces. Inside the house, space sprays containing pyrethrins or pyrethroids are effective in killing spiders. Space sprays have little residual activity and should be applied when spiders are noticed. Dust formulations can be used in crawl spaces, attics, and utility areas to provide long-term protection. The insecticidal dusts tend to cling to the spider webs for long periods of time. When spiders chew their webs to recycle the silk they consume the toxicant and die.
I hope this helps anyone who reads this.
