You might think opening your window for fresh air is a good idea. It’s not. Screens get holes. Spiders are tiny acrobats. If you leave the window open at night, you are sending out a party invitation. Close your window before dusk. Or invest in a window screen repair kit. It’s boring, but it works.
And for the love of all that is holy, check your ceiling corners. That’s where they build their webs to lower themselves down like little bungee jumpers. If you see a web, destroy it. Be ruthless. No mercy for the architects of nightmares.
