Dogs With Parasiticides Poison Water Bodies

Most dog owners are unaware that flea and tick repellents are dangerous to aquatic life. A study on Hampstead Heath shows that ponds where dogs are allowed to swim contain levels of two pesticides harmful to invertebrates. The pesticides imidacloprid and fipronil are used as parasiticides for flea and tick infestations in cats and dogs using spot-on formulas and flea collars, despite the fact that the chemicals were banned for agricultural use in 2018 due to their toxicity to bees and other insects.
