![]() ![]() This allows the two active ingredients to be effectively absorbed by the oils of the skin continuously. Seresto achieves this through the drugs being secreted in low doses by way of a special polymer matrix design of the collar. The second is that unlike some (much cheaper) flea and tick collars, the Seresto collar more effectively treats the whole cat’s body versus just the areas closest to the collar, providing better flea and tick control. The first is that it claims an efficacy that lasts for eight months, which is longer than any other flea/tick product on the market. The Seresto collar has a couple of other advantages over other common flea and tick collars. Many other common topical and oral flea and tick products do not provide repellency and require the insect to bite the skin in order to die.Ĭats with a high sensitivity to flea bites or cats with a flea bite allergy may find more relief with a product that prevents flea bites. The Seresto collar’s main advantage over many other flea and tick prevention products is that it provides repellency against fleas and ticks while also killing any that come in contact with a cat wearing the collar. In regard to kill time, there are certainly other topical products that work faster to kill fleas and ticks. According to the manufacturer, Seresto can also impact flea infestations by affecting flea larvae that have come in contact with the collar. ![]() It can kill adult fleas within 24 hours after initial application and ticks within 48 hours. The Seresto collar repels adult fleas and ticks. What Does the Seresto Collar Do for Cats? It is able to kill all stages of the tick, including the adult, larva, and nymph forms. It also has a very high affinity for invertebrate (insect) nerve tissue, lending to its safety for use in dogs and cats.Īs an acaricide, flumethrin is principally effective against ticks. Its action leads to repeated nerve impulses that lead to death of the insect. It does not have additional efficacy against fleas eggs and only an indirect effect against larvae, though it can kill adult fleas quickly before they can lay eggs.įlumethrin is a pyrethroid insecticide that conveys its action through voltage gated sodium channels in nerve tissue. Imidacloprid is largely effective against adult fleas only. These receptors in insects have a much higher affinity, or desire to bind, to imidacloprid than to similar receptors of vertebrates like cats and dogs. Imidacloprid is an insecticide that acts on the nicotinic acetylcholine receptors of the central nervous system of a flea, leading to central nervous system (CNS) impairment and death. ![]() The Seresto collar contains two active ingredients: imidacloprid and flumethrin. Products should be used before the expiration on the package. ![]()
