After about 2 years of a constant flea battle... we tried everything on the market (Frontline, Advantage, Comfortis, Trifexis, etc.) in combination with bombing and yard spraying, I finally was recommended the Sseresto flea collar. I figured, why not? For it's price I decided to only get 2 collars at first. (We have 3 dogs and 2 cats). Withing 24 hours, we saw a drastic decline in the number of fleas in the house. Of course we had it at a disadvantage with 3 animals for them to still feed on. I went ahead and got 3 more collars. 24 hours later, NO FLEAS. We came across a couple of fleas in the following days, but they were obviously dying and begging to be put out of their misery. lol. One of my cats had a sensitivity to fleas. Her skin was always inflamed and red and she was missing half her fur. Within a few weeks, her skin healed and was growing back a beautiful fluffy coat again. This is the best product i have bought in a long time. and if it lasts the 8 months it claims, it is a bargain. Try it, you won't be sorry! I run a pet sitting business and I have been boasting about it to my clients and on social networks. Love love love love it!
Everything! Easy to use. Doesn't smell. 100% effective. Even comes with optional safety reflectors. Great for spotting my black dogs at night in the yard. :)
