Virbac Knockout E.S. Area Treatment Spray 5 5 2 2
Great product! We used this home spray last year, when we had a ridiculously heavy flea infestation. We got it from our vet, and after flea baths, Comfortis, spraying the yard, and then vacuuming and spraying with this product, we had no more fleas, for a year! Saw the first fleas today, so it is time to spray! It really does last 7 months! May 31, 2014
Great product I have used this for years, and it really works, but everyone needs to understand that if you have a mild or heavy flea problem, you must treat the yard, house and your pets all at the same time. If all 3 are not treated at the same time people think that this and other products do not work. May 31, 2014
