It works! The first product we've ever used that actually kills fleas!
Reviewed in the United States on May 25, 2017
We have an outdoor dog that is absolutely covered in fleas nearly year round, since we don't get hard freezes here in North Carolina. We've tried Frontline, Capstar, Program, Advantage, flea collars, flea shampoos, spraying fipronil in the area around the barn where he lives, diatomaceous earth, brewers yeast and garlic, cedar oil and cedar chip bedding, and nothing worked. We even used corn oil to coat and suffocate the fleas, which worked but only for a day or two. I was convinced that these are zombie fleas and immortal. And the poor dog was miserable and scratching.
I hesitated to pay $50 for a flea collar that might not work, but took the chance and ordered this Seresto collar. We put it on the dog two days ago, and I'm amazed! The first day, we noticed that the fleas on the front half of his body were gone. Today we didn't find one single live flea on him, nostrils to tail tip. We did notice some dead ones on him. This is the first thing we've ever found that got rid of/killed the fleas! He was lying happily in the sun this morning, not scratching or twitching, for the first time in months.
Since the collar worked, I've also ordered one for our little indoor dog and the indoor cat, who also have fleas (but not as many). If these collars really kill the fleas for 6-8 months, they are worth every penny of the cost. I will update my review after a few months, to report whether or not the flea killing effect lasted. I'll also keep an eye out for irritation, baldness or oozing sores where the collar lies (since some pets have had an adverse reaction to collar) and report that here if it happens.
For now, I'm very, very happy to have something to help combat the fleas!
Edited 6 June 2017: It's only been a few weeks but I wanted to update. No fleas on the pets - if they pick one up in the grass it hops off without biting. The small dog was a little lethargic for a day or so (just acted tired and didn't want to play - he was still eating) after we put on his collar, but we kept a close eye on him and he was back to himself on the third day. No rawness, sores or extreme symptoms from any of the pets. I also set off some Hot Shot flea fogger/bombs in our carpeted bedrooms, where we had fleas (the pets sleep with us). Between the collars and the bombs, we are finally, at long last, flea free! I'll update again at the end of the collars' lives to report how long they lasted. Buy this collar - you won't regret it!
