Do you have to wash everything in the house to rid fleas or can you tumble dry items?

While washing items in hot water is effective for killing fleas and their eggs, you can also use a tumble dryer as an alternative. Tumble drying clothes and bedding on high heat for at least 30 minutes can help eliminate fleas, larvae, and eggs. However, for a thorough flea control strategy, it's best to combine both methods along with vacuuming and treating your home.
