If your furniture has removable covers (bless your smart-buying soul), rip them off and wash them in hot water. I’m talking “scorching hot, the kind you imagine a lobster would complain about” hot. Fleas and their eggs detest temperatures above 130°F, so crank that dial like you’re auditioning for a laundry-themed superhero movie.
Then, dry those covers on the highest heat setting. The dryer is your silent, spinning assassin—it cooks any survivors with the gentle warmth of a slow-roasted apology. For non-removable furniture, skip this step and rely on your vacuum and the other weapons we’re about to unleash.
