Now, let’s get weird. Buy some food-grade diatomaceous earth. It sounds like a fancy French condiment, but it’s actually the fossilized skeletons of tiny sea creatures. To a flea, this dust is like walking through a field of razor blades.
Sprinkle a light, even dusting over your furniture, especially in the seams and crevices. Let it sit for 24 to 48 hours. The fleas walk through it, get cut up, and dehydrate into tiny, crispy remains. It’s nature’s slow-motion horror movie. Just wear a mask while applying it—you don’t want to breathe that stuff in.
