Here’s a little spider psychology: They see a web, they think, "Ah, home." If you knock down every web you see for two weeks straight, they’ll get the hint. They’ll realize this is a hostile environment. They’ll move to a house that leaves its webs up. You know, the slobs down the street.
Use a long broom or a duster. Don’t use your hand. That’s a panic attack waiting to happen. Just sweep the web into a dustpan and flush it. Yes, flush it. Down the toilet. Show no mercy.
