There are two types of flea sprays for pets – natural and chemical-based products. An all-natural flea and tick control treatment in most cases repels fleas but doesn't eliminate an infestation.

On the other hand, chemical-based treatments are very effective at killing and preventing flea and tick infestation for up to several weeks or months. However, they should be properly administered to avoid the risk of putting your pet in danger.
