A bite from a poisonous spider should be treated by a physician. Spider populations can be controlled by a combination of sanitation and insecticides. Most spiders are regarded as beneficial and should not be destroyed. Many people fear spiders because of stories or myths about them. Others object to spiders because of their habit of building webs in and around the home.
Spiders are most visible and cause the most concern in the fall, when they often move into homes.
Spiders differ from Insects in that they have eight legs rather than six and only two body regions instead of three. Some spiders spin a web, others do not. Indoors, many spiders may be found in basements, crawl spaces and other areas where it is somewhat damp. Other spiders, however, prefer a drier situation and can be found in the upper corners of rooms, in attics or in floor vents. After mating, female spiders lay eggs in clusters called egg sacs.
