Spiders, known as arachnids of the class Archnida, are beneficial creatures that can rid the home of other insects, which they attack and consume as food. While a few spiders can offer help in eliminating annoying bugs, certain spiders secrete poisons when they bite their prey, which can be harmful to both animals and humans. While it is impossible to rid a home of all spiders, precautions can be taken to stop arachnids from traveling freely into your home.
Apply weather stripping to all doors and windows. Weather stripping can prevent spiders from entering the home through gaps underneath the doors and in spaces and cracks along windowsills.
Regularly dust behind and inside bookcases and entertainment centers. Vacuum all baseboards and corners of the home. Removing dusty areas is another way of eliminating areas where spiders can hide.
