While parasites like ticks, worms and fleas are bad for our pets, their treatment can be bad for the environment!
Some contain neonicotinoids which are banned for farming but still used in pet treatment. If these ingredients get in waterways or grasslands they can be bad for natural insects.
You should use these medications but be careful where your pet goes afterwards. Don’t let them swim in rivers or run through long grass for 48 hours after you’ve treated them!
