Toxic chemicals in pet flea treatments harming wildlife, UK study warns

A UK study warns that chemicals fipronil and imidacloprid used in pet flea treatments are harming wildlife in rivers, parks, and conservation areas, despite being banned as pesticides. These toxic chemicals are causing irreversible damage to aquatic life, birds, and pollinators, and have also been linked to lower cognitive scores in children with autism. The study calls for urgent government action to restrict their use.
