These chemicals, often found in spot-on treatments, sprays, and collars, are extremely harmful to insects and other freshwater organisms. Reducing their release into water protects river ecosystems.

Many flea and tick treatments remain active on a pet’s fur for up to 28 days, meaning chemicals can wash off into rivers and ponds during that time. Keeping pets out of natural water bodies during this period helps protect aquatic life from toxic exposure.

Fur from treated pets can carry insecticides. Birds collecting it for nests may expose chicks to these harmful chemicals, affecting survival and growth.

Research shows fipronil was detected in 98% of samples, and imidacloprid in 66%. This highlights the pervasive impact of common pet treatments on freshwater ecosystems.

Protecting rivers from chemical pollution involves multiple actions. Pet owners can reduce harm by using flea treatments only when necessary, consulting their vet for safer alternatives, keeping treated pets away from natural water bodies, cleaning pet items properly, and disposing of fur safely. Together, these steps help safeguard aquatic life and maintain healthy river ecosystems.
