You don’t need chemicals. Spiders have a superpowered sense of smell. They hate certain things. Use it against them.
Peppermint oil is kryptonite. Mix a few drops with water in a spray bottle. Spritz it around windowsills, baseboards, and door frames. They hate the smell.
Another trick? Chestnuts. Yes, chestnuts. Place a few in corners. Myths say spiders avoid them. Science isn’t 100% sure, but it’s a fun, cheap experiment.
Vinegar works too. Mix equal parts water and white vinegar. Spray it. The smell goes away quickly for you, but spiders detest the residue. You’ll smell like a salad, but no webs.
Bonus: The Lights-Out Trick
Outdoor lights attract insects. Insects attract spiders. Simple math. Turn off your porch light at night, or swap it for a yellow bug light.
Yellow lights attract fewer bugs. Fewer bugs mean hungry spiders go somewhere else. It’s like cancelling their dinner reservation.
And here’s a wild fact: Some spiders can “balloon” through the air on silk threads. They travel miles on wind. Grounding your outdoor lights won’t stop that, but it helps keep the webs off your front door.
