Springtails
Springtails are minuscule insects that get their name from the spring-like mechanism on their bodies, which allows them to jump when disturbed. They’re attracted to bathrooms with high humidity, where they feed on mold, algae, and organic debris. If your tub or sink drain has residue, you might see springtails hopping around in the water. Keeping surfaces clean and dry is the best defense, along with running an exhaust fan after showers to lower moisture levels. It also helps to periodically scrub the shower curtain or bath mat if they stay damp, since that’s where springtails love to hang out.
