Reasons Why Spiders Like Basements

Reasons Why Spiders Like Basements
Basements provide an ideal environment for spiders. They are dark, damp and often undisturbed, making them a perfect place for spiders to build webs and hunt for prey. Additionally, basements often contain items such as cardboard boxes, furniture, and other clutter that can provide ideal hiding and nesting areas for spiders. Basements are also often located near windows and doors, providing spiders with easy access to the outdoors. This provides spiders with the perfect opportunity to hunt for food and build webs, as well as providing them with a steady source of prey.

What Attracts Spiders

What Attracts Spiders
Spiders are drawn to warm, dark and damp places, making basements a prime spot for them to hide and build webs. To keep spiders out of basement, it is important to understand what draws them in the first place.

Spiders feed on insects, so an abundance of bugs in the basement is a sure-fire way to attract them. Insects are drawn to mess and clutter, so keeping the basement free of debris is important. Spiders also thrive in damp environments, so any moisture or water problems should be addressed.

Spiders also like to hide and build webs in small, dark spaces, so sealing off any small crevices and cracks, such as around window frames or door frames, will prevent them from entering the basement.

Finally, spiders are more likely to congregate in places where they can find food, so removing sources of food, such as pet food and crumbs, will help to keep them away.

Insects are a major source of food for spiders. As such, reducing the number of insects in the basement will help keep spiders away. Remove standing water and inspect and seal crevices to reduce the number of insects. To further reduce the number of insects, keep food in airtight containers, remove piles of wood, leaves and other debris, and regularly vacuum and mop floors. Outdoor lighting may also be helpful in attracting fewer insects.

2. Clutter

2 If you have items stored in the basement, keep them in sealed plastic containers.
3 Organize items in the basement, keeping items off the floor and on shelves.

3. Moisture

  • Check for any signs of water damage, such as water stains or mold.
  • Check for any plumbing leaks.
  • Check for any other sources of moisture, such as humidifiers, air conditioners, or other appliances that produce moisture.
  • Check the basement walls and floor for moisture.
  • Consider using a dehumidifier to reduce the amount of moisture in the air.
  • Check for any cracks or gaps in the walls or floor that may be allowing moisture in.
  • If possible, reduce the amount of moisture in the basement by using a fan to circulate the air.

4. Light

Spiders prefer dark and secluded places, so keeping your basement lit can discourage them from entering. Place bright lights around the perimeter of the basement, and near any entrances. If possible, keep the lights on all night, as spiders are less active in the light. This may require investing in a timer or a motion-sensor light. Additionally, use LED or fluorescent bulbs to reduce the amount of heat produced, as spiders are more likely to enter areas with high temperatures.
