Spiders

Most spiders feed on other insects and if you have spiders in or around your home you may have an insect problem as well. Spiders have eight legs and venomous fangs and are active all year, preferring to live in dark crevices where they can easily trap their prey. Most spider species live about one year.

Spiders are generally solitary predators, coming together only to mate. Females will create an egg sac for her eggs, which they guard carefully. If the female spider dies before her eggs have hatched another female may take over protecting her egg sac.

Spiders are highly territorial and will fight another spider to gain dominance over a space they have claimed as their own. Most spiders will bite animals and humans if they are attacked or trapped.

Entry: Spiders gain entry to your home any way that they can, in search of insects to eat.

Nest Locations: Spiders will seek dark corners or crevices to spin their webs. You’ll find them in basements, up in rafters, under porch chairs, behind shelving and seldom used garden tools and boxes.

Do-it-yourself Effectiveness: Keep your home clean and clear of dusty places where spiders and other insects can hide. Sweep dust and clutter from basements, crawl spaces, porches, sheds, and outdoor spaces that would encourage spiders and insects to gather.
