Spiders rarely bite people and there are only a few spider species in India that can be considered dangerous. Spiders can be a particular nuisance in the home. They are attracted to warm, dark small spaces, like wall cracks, corners, air vents, and in the eaves of your home. Spiders are most likely to enter the home in the fall due to their search for a warm place to spend the winter.
Spiders commonly enter homes in two primary ways: entering through open, poorly screened windows and doors and through cracks and gaps around door and window frames. Most of the time, spiders come inside the home looking for prey. The other common method of entry is accidentally hitchhiking inside boxes, on outdoor items and numerous other things that are brought inside a home or business.
