Spiders rarely bite people and are generally divided into two types - black widows and brown recluse - which are considered dangerous. Most spider bites have no impact or little impact on humans, while other spiders have bites that cause minor medical problems. Many people are afraid of spiders.
Spiders can be a particular nuisance at home. They are attracted by warm, small and dark places such as crevices, corners of the room, air vents and on the fringe of the house. Other species love open spaces and make nests in gardens, or on outside lights. Spiders are generally a problem because of the nest.
