How to get rid of spiders in the house
Spiders show up because other bugs do. The fastest fix is mechanical (vacuum webs, declutter) plus a perimeter treatment outside. Most house spiders are harmless and actually eat other pests — the goal is keeping numbers down, not eradication.
Tools
- ✓Best tool for webs and egg sacs.
- ✓For ceilings and high corners.
- ✓Outside, for sweeping eaves and exterior walls.
Materials
- +Cedar oil based, safe around pets. Treats baseboards, corners, window frames.
- +Stronger residual outdoor perimeter spray.
- +Add 15 drops to water in a spray bottle for natural repellent in closets and basements.
- +Place in corners, behind furniture, in garage — catches what you don't see.
Steps
-
1
Vacuum every visible web
Go room by room. Get ceiling corners, behind furniture, under sinks, the corners of every window frame. Webs hold eggs — vacuuming them up beats spraying.

2
Reduce clutter and food sources
Pull boxes off basement and garage floors. Fix outdoor lighting that's drawing other insects (swap white bulbs for yellow). Less insect activity = fewer spiders.

3
Treat the interior perimeter
Spray Wondercide along baseboards, around window/door frames, in basement corners. Let dry. Reapply every 30 days indoors.

4
Treat the exterior perimeter
Spray a 3-foot band around the foundation with Ortho Home Defense. Hit eaves, window frames, garage door tracks. This is where spiders enter.

5
Set sticky monitors
Place glue boards in closets, basement corners, behind the toilet, in the garage. They tell you whether spider pressure is still high week-to-week.
