Spiders
Many species of spiders are common household pests in the United States.
Some Spiders populations are found in humid and moist locations like basements and crawl spaces. Other Spiders prefer dry and warm places. They can be found in upper corners of rooms, garages, fence line, eves and attics as well as sub floor air-vents.
Spiders prefer to hide in dark areas and in cracks as a retreat in order to construct material for their webs.
Spiders can be beneficial in the yard or garden by keeping the insect population down, particularly ones that can spread disease, such as mosquitoes, flies, fleas and roaches.
Spiders breed throughout their life cycle and just one spider egg sac can contain anywhere from 100 to 3,000 eggs.
Of the thousands of arachnid species, there are only two that are both aggressive and dangerous to humans: the black widow spider and the brown recluse spider. If these Spiders are found, pest control treatment should be considered.
SAFETY: If you suspect you’ve received a black widow or brown recluse spider bite, seek medical attention immediately.
