When fleas and ticks have your yard under assault, Vet’s Best Flea + Tick Yard & Kennel Spray for Dogs & Cats fights back with its unique blend of certified natural essential oils and plant-based ingredients. Peppermint oil and clove extract (eugenol) help control and kill fleas, flea eggs, and ticks on contact, and also repels mosquitoes too! It’s DEET-free and uses absolutely no chemical pyrethrins, permethrins or cedar oil, so it’s safe for the whole family. The non-staining formula can be used on turf, lawns, kennels, patios and other outside surfaces.
