Summer Travel Tip: Pour Dawn Down Your Drains Before Leaving.
TikTok creator Lexi Stout advises pouring Dawn dish soap down all the drains in your home before leaving for summer travel to prevent pests like cockroaches from crawling up. The surfactants in the soap reduce the surface tension of water, suffocating and immobilizing insects that come into contact with it. Bleach can also be poured down the drain to keep rats and mice away, while steel wool can be used to seal holes in the apartment. A spray bottle with equal parts dish soap and water can be used to spray cockroaches instead of using toxic roach repellents.
