Spiders are common household invaders that often enter homes while hunting insects. While most spiders are harmless, their webs, egg sacs, and sudden appearances create concern for many homeowners.
How to Identify Spiders
Spiders have eight legs, two body segments, and no wings. Common indoor spiders include house spiders, cellar spiders, wolf spiders, and jumping spiders.
Why Spiders Invade Homes
Spiders follow their food source. Homes with flies, ants, and mosquitoes naturally attract spiders. Entry points include gaps around doors, windows, vents, and foundations.
DIY Prevention Methods
- Seal exterior cracks and install door sweeps
- Reduce indoor insect populations
- Remove webs and egg sacs regularly
- Declutter basements, garages, and attics
- Use yellow outdoor bulbs to reduce insect attraction
Natural & Non-Chemical Controls
- Essential oil sprays (peppermint, eucalyptus, tea tree)
- Sticky traps in corners and closets
- Vacuum webs, spiders, and egg sacs
- Outdoor habitat reduction
Store-Bought Control Options
- Residual perimeter sprays
- Spider glue boards
- Crack-and-crevice insecticides
When to Call a Professional
If venomous species are suspected (such as black widows or brown recluses), or spiders are persistent throughout the home, professional inspection is recommended.
