The flea and tick preventative Frontline comes in three different formulations. There are two spot-on products: Frontline Top Spot and Frontline Plus. Each individually packaged vial contains a small amount of liquid that you place on one or two locations under your dog or cat’s fur. Both include fipronil, the active ingredient that kills adult fleas, ticks and some other types of external parasites. Frontline Plus also includes an insect growth regulator to kill juvenile fleas.
However, a good option that is often overlooked is Frontline Spray. The active ingredient in Frontline Flea Spray is also fipronil. Why would a pet owner pick a spray over the top spots? Three scenarios come to mind. First of all, Frontline Spray can be used on cats and dogs of all sizes. So, if you have a herd in your house, having just one bottle of spray to use on everyone could be more convenient in the long run than wading through all those different doses of top spots. Also, using Frontline Spray for flea control is cheaper than either Frontline Top Spot or Frontline Plus.
Finally, Frontline Spray for dogs and cats kills fleas and ticks more quickly than the top spots do. This is why the spray is popular with many veterinary hospitals, animal shelters, and anyone who is potentially faced with dogs and cats with terrible flea and tick infestations.
Frontline spray flea control is easy to use. Just one or two pumps per pound of body weight kills ticks for a month and fleas for up to three months. People applying the spray should protect themselves from overexposure by not breathing it in, wearing latex gloves, and washing up afterwards with soap and water.
