Yes, bleach can kill fleas, but it is not the most effective or safest method for flea control. Bleach contains strong chemicals that can eliminate fleas by breaking down their outer shells and disrupting their respiratory system. However, there are several factors to consider before using bleach to tackle a flea infestation.

How Bleach Affects Fleas

Kills Fleas on Contact – When directly applied, bleach can kill adult fleas and their eggs. However, fleas move quickly, making direct application difficult.

Disinfects Surfaces – Using a bleach solution to clean floors, pet bedding, and hard surfaces can help eliminate fleas hiding in these areas.

Dangers to Pets and Humans – Bleach is toxic if ingested or inhaled by pets and humans. It can also damage fabrics, carpets, and furniture.
