What are Brown Recluse Spiders?

Brown recluse spiders are shy, solitary, and venomous spiders. Brown recluse spiders are named so because they are loners. They avoid humans and prefer to hide in isolated places, and are known for their secretive behavior.

Brown recluse spiders are dangerous and are found mostly in the Southeast and Midwest of the United States. They often sneak into yards and basements to take shelter in warm, dry, and dark settings, perfect for their living. They prefer to live outdoors and are typically found outside around rocks, woodpiles, under bark, etc. Inside the home, you can spot brown recluse spiders in undisturbed spaces.

They are nocturnal hunters and are most active at night. They can survive without food for months. Brown recluses normally feed upon nuisance insects, like flies and mosquitoes.

These spiders are non-aggressive. They do not bite on purpose but as an act of defense. Although the chances to harm you are thin, they won’t hesitate to bite if they feel threatened.
