The article explains that UCR entomologists discovered bed bugs have a surprising weakness: they strongly avoid water and wet surfaces. Researchers found that moisture can trap bed bugs and block their breathing openings, causing them to quickly turn away from wet areas. The study showed that bed bugs of all ages and both sexes avoid moisture, with younger bugs reacting even more quickly. This discovery could improve bed bug control because water-based insecticides might cause the insects to flee to untreated areas, so researchers may need to consider their behavior when developing new treatments.
