You might think outdoor lights repel spiders—nope. Lights attract moths, moths attract spiders. You’re hanging a dinner bell over your porch.
Switch your outdoor bulbs to yellow "bug" lights or sodium vapor lamps. Spiders will look at your house and think, “Ugh, cheap lighting. No thanks.”
Or just turn off the lights at night. Sit in the dark. Let the spiders wonder if you’re a ghost. Mind games.
