“Where I live there is a real flea problem. We could treat our yard but because of all the cats and animals that run through our yard on daily basis, fleas will just come back. Topicals did not work. Nor did the use of Topicals with other flea products that you spray on your pets and flea baths. We also tried flea products to use in the home on upholstery and flea bombs. When we tried Simparica, the problem went away immediately. No fleas on the dogs or in the home. Wish I had tried this first! Worked for both my 35lb and 8lb dogs.”
