これさえ読めば安心! How to Keep Spiders out of Your Houseの活用法をステップバイステップで解説します。

This sounds like a fancy skincare product, but it’s actually fossilized algae ground into a white powder. To spiders, it’s like walking through a field of razor blades made of microscopic glass. They walk over it, get tiny cuts, dry out, and die. It’s gruesome, but it’s also pet-safe and food-grade—so your dog can lick it and just get weirdly dusty.

Dust a thin line along baseboards, behind appliances, and under sinks. Don’t pile it up like a cocaine mountain; a light dusting is enough. You’ll find crispy spider mummies in a week. Nature is brutal, but your living room doesn’t have to be.

Declutter like You’re Trying to Impress a Robot

Spiders are basically tiny cowboys looking for cover. Piles of clothes, cardboard boxes, and stacks of magazines are spider condos. They love dark, quiet spots where no human has stabbed a finger since 2019. Go through your basement. If you haven’t touched a box since the Obama administration, throw it out.

Vacuum regularly, including under the couch cushions. I once found a whole spider family living inside a forgotten throw pillow. They had a tiny web, an egg sac, and probably a mortgage. Don’t let them nest. Vacuum like your sanity depends on it—because it does.
