Found only one flea on my dog after treatment. Is that normal?

Typically, a topical treatment works by killing the flea when it bites the dog and sucks it's blood. Because it was live on your dog, it hadn't had a chance yet to bite him and diet. Even if there are more, they will die as soon as they bite your dog thanks to your stringent flea treatments. It's not something I would worry about since he's treated and you found no more on him, but if you wanted to be safe, you can give him Capstar. It's a one time pill that starts killing fleas in 30 minutes, and it's safe to give him now. I really think it was one he picked up outside. I hope this helps!

I would say it's safe with one flea killed and no more signs seen. Theoretically, they could live in house plants, but again since you haven't seen anymore, I wouldn't be worried about it. You are on top of it if you have an exterminator spray, and to give you peace of mind, you can have them come again now :-)

One flea is possible but not likely. The majority of a flea population lives off of the pet and in the surrounding environment. To be safe and to prevent an infestation, use a topical or oral flea preventative for at least the next three consecutive months, preferably year round. Your veterinarian can dispense CapStar, which will kill any adult fleas on Jake within 30 minutes of administration, if necessary. Vacuum everywhere and dispose of the bag or empty the canister outdoors immediately after. Wash all bedding in hot water. Use an area treatment, such as Knockout ES, to prevent infestation.

Hello there. Unfortunately, the adult fleas you found on Bella only make up about 5% of the fleas in her environment. The rest of the fleas are eggs, larvae, and pupae, which can remain in your carpet, floorboards, and furniture for months. The only way to truly insure Bella is flea free is to use a high quality flea preventative. I recommend consulting with your veterinarian to determine what type of flea treatment is best for Bella (prevention comes in topical, oral, and collar varieties). Hope this helps!

If you haven't seen any other signs of fleas, then yes I would say you are in the clear. If your dog does pick up another flea in the year, then yes it will die when the flea bites your dog due to the monthly topical treatment :-)

It might be a flea that jumped on him after the application, this can happen but if you find more than one and they are alive then the product you are using is likely not working and you need to change it to something else such as Bravecto, Advantage or Revolution.

If you found one flea in your yard, I would bet that it is only the tip of the iceberg! Please make sure your pets are on a high quality flea preventative monthly and consider consulting an exterminator regarding flea control in your yard. Examples of flea preventatives for pets include Nexgard, Bravecto, Comfortis or Advantix for dogs and Advantage or Revolution for cats.
