If you’re still seeing fleas after three days, upgrade to food-grade diatomaceous earth. Sprinkle it lightly on the couch, rub it in, and leave it for 24-48 hours. It’s made of microscopic fossilized algae that shred fleas’ exoskeletons, causing them to dry out and die.
Use a mask when applying—this fine powder can irritate lungs if you breathe it in. Also, keep pets away while it’s sitting (they might lick it, though it’s nontoxic in small amounts). Think of it as a breadcrumb trail of doom for fleas.
