Is apple cider vinegar safe and effective for flea control on pets?
Thanks for using Petco Pet Education Center, formerly Petcoach! There isn't any concern for over-exposure to the vinegar or water, but I would recommend a different approach for flea control. That mixture will not control fleas. The best treatment is monthly flea prevention from your veterinarian, given every 30 days for at least 3 months. Products purchased over the counter and flea collars don't work. You must treat all the pets inside and outside your home. I would also recommend a product called Knockout Spray for inside the home. You need to focus on dark areas, like under furniture, and treat any hard floor surfaces as well. After the product dries, vacuum thoroughly and throw out the bag or clean out the canister if bag-less. Apple cider vinegar will not fix your flea problem, and will only prolong the discomfort to your pet. I know the products seem expensive, but they truly work and in the long run is cheaper if you follow the flea treatment steps. Good luck and kisses to Gracie!
