This stuff worked just as it said it would. My dog stopped scratching within the hour. Gave him a pill Sunday, Monday, Tuesday in the morning and gave him a good bath, he hasnt sctrached very much at all. i will save the remaining 3 for another time. My order was ready for pickup the dame morning i placed order and the guy who brought my order to my car was fast, i had 1-2 minute wait and that all. Awesomeness

Capstar Works very well! along with a daily cleaning and laundry routine, it really helped to knock out the fleas on my dog as well as in my house quickly. it takes some time to fully get rid of the eggs that have fallen off of my dog, but there has not been a flea on him in over 8 days. I still see some fleas here and there, maybe one a day, But continuing my cleaning and laundry and vacuuming, as well as using a flea comb on my dog daily, everything has drastically improved. do not use this alone. you're going to need to get household sprays, yard sprays, if we come for your animal and be consistent in vacuuming sweeping and laundry every single day for weeks. it sucks, but it's worth it in the end.

Capstar Flea treatment

It's a fair price and gets the job done. It isn't instantly, but by washing the dog and adding other flea sprays it definitely all works with it. I would recommend for people that can't afford the better products and need results. I definitely will be buying again. In a week I've already seen a difference.
