Bothered by spiders setting up shop inside your house? Spiders often come indoors seeking warmth and food: You can get rid of spiders with a little patience and the right tactics – but act quickly before they have a chance to lay their eggs!
Kill on Sight
Spiders don’t infest a house en masse unless their eggs just hatched. That means that killing every spider you see is actually an effective way to keep spiders under control, especially when combined with our other steps. Also, jumping spiders and similar species are experts at slipping under baseboards or into corners, so kill them fast on sight before they can get away.
Clean Up the House
While you are nabbing every spider you find, it’s also time to clean up the house. First, take a broom or cobweb cleaner and clean out all corners, ceiling spaces, fans and other areas where webs build up. Even if the spider is dead, those webs could still be harboring eggs or hiding rival spiders waiting to take over.
With that done, do a thorough vacuuming of all your carpets and baseboards. Make sure you get in the corners, too. This helps get rid of spiders, spider eggs, and spider food (other bugs) that may be hiding in the cracks around your floors.
Seal Your House Well
Spiders will eventually dry up and die out if they can’t catch anything. That’s why it’s important to seal your house well: Even if a spider makes it in accidentally, they won’t have a food source. Keep your windows fully screened when open, and make sure your weatherstripping around doors and windows isn’t leaving any gaps. Take care of other flying pests quickly before spiders start to feast!
Use Residual Sprays
For a bad infestation, such as a recent outbreak from a spider egg, you may want more powerful measures. Look for a residual spider spray you can use. These pesticides are toxic, but they create a lingering patch of poison that will continue to kill spiders for weeks if any new invaders try to set up. Try to use them in out-of-the-way corners where spiders like to hide, away from pets and kids.
