Spiders are attracted by a few main things:

1. Food: Spiders eat other insects. So, if there’s a large number of pests in your home, spiders might be attracted to that plentiful food source.

2. Shelter: Spiders need a safe place to hide from predators and unfavorable weather conditions. Homes provide lots of nooks and crannies that make perfect hiding places. Some spiders prefer dark, damp places like basements or bathrooms, while others prefer dry, warm areas like attics.

3. Water: Some species of spiders are attracted to moisture, so they can often be found in damp areas such as basements, bathrooms, and plumbing fixtures.

4. Mates: If you have one spider, it might attract others. Spiders will seek each other out when it’s time to mate.

5. Light: Many spiders are nocturnal and are attracted to light, because they know that’s where they can find food. Light attracts insects, and insects attract spiders.

6. Warmth: Spiders are cold-blooded and are attracted to warm places when the weather is cold.

Please note that spiders don’t typically seek out human interaction and most of them are not harmful to humans. In fact, they can be beneficial as they control the population of other pests. However, if you have an infestation or a poisonous spider, you might need to take action.
