Spiders are tiny, but they’re not Houdini. They get in through gaps you didn’t even know existed. Check your window screens, the bottom of your doors, and those weird cracks around your baseboards. If you can slide a credit card through a gap, a spider can waltz right in. Grab some caulk or weatherstripping—it’s cheap, and it works better than any essential oil blend.
Oh, and check your vents, too. I once found a funnel web spider in my air conditioner. I’m not kidding—he was living his best life, cooling off and eating flies. That’s my fault for not replacing the mesh. Your fault? Probably not, but now you know.
