We stock a range of flea sprays for use in the home and on your pet. All of our flea spray products are designed to kill fleas fast. However re-infestation can occur where larvae are present and hatch at a later stage. Our Johnsons 4 fleas spray kills fleas and their larvae greatly reducing the risk of re-infestation. At Petcara, you can buy flea spray for carpet, furniture and dog bedding.
