Bio Spot Defense Flea & Tick Spray for Cats & KittensOur Bio Spot Defense Flea & Tick Spray for Cats & Kittens is easy to use and controls fleas, ticks and flea larvae. This flea & tick spray combines the adult flea killing power of etofenprox with the long-lasting flea egg-killing power of Precor Insect Growth Regulator. This highly effective combination of ingredients provides quick relief from biting fleas and continuous killing of flea eggs laid on the animal, breaking the flea life cycle. The elimination of both adult fleas and flea eggs is important because adult fleas live on your pet, causing discomfort and skin irritation, while the vast number of eggs that they lay fall off and develop in your house. This fast-acting formula also repels mosquitoes!
