Common Locations for Red House Spiders

Dark and secluded areas of homes, garages, and barns are often where you’ll find the common locations for red house spiders. These spiders prefer areas with low human activity, allowing them to build their webs undisturbed and catch prey. Here are some common locations where you may come across red house spiders:

  • Underneath furniture: Red house spiders like to hide beneath sofas, chairs, and tables, where it’s dark and cozy.
  • In dark corners: They often build their webs in corners of rooms, especially in areas that aren’t frequently visited or cleaned.

Preventing Red House Spider Infestations

To prevent red house spider infestations, take proactive measures to seal cracks, gaps, and holes in the exterior of your building. Red house spiders can easily enter your home through these openings, so it’s important to make sure they’re properly sealed.

Here are four steps you can take to prevent red house spider infestations:

  • Inspect and seal: Regularly inspect the exterior of your building for any cracks, gaps, or holes. Use caulk or weatherstripping to seal them off, making it difficult for spiders to enter your home.
  • Repair window screens: Check your window screens for any holes or tears and repair them as needed. This will help keep red house spiders out of your home while still allowing fresh air to come in.
  • Maintain cleanliness: Keep a tidy environment inside your home to avoid attracting spiders’ food sources. Practice good housekeeping by regularly dusting and vacuuming your home, and promptly clean up any food spills.
  • Keep outdoor areas clear: Trim back grass, plants, and branches away from the main entrance of your home. This will discourage red house spiders from entering your home and creating webs near the entrance.
