Do fleas have to bite for Seresto to work

No, fleas do not have to bite for Seresto to work. Seresto is a long-lasting flea and tick treatment that offers continuous protection for up to 8 months without a single bite. This is because Seresto releases the active ingredients in low concentrations from the collar’s plastic matrix, killing fleas and ticks before they actually reach your pet, meaning they’ll never even have the chance to bother them with a bite. The active ingredients are also released in larger amounts when your pet experiences contact with fleas and ticks, leaving them unable to survive. Due to its efficacy and longevity, Seresto is considered by many as one of the most effective flea prevention products on the market.

What is Seresto?

Seresto is a flea and tick collar from Bayer Animal Health that is designed to protect pets from these pests. The collar offers up to 8 months of protection against fleas and ticks for cats and dogs. It works by releasing an active ingredient, imidacloprid, into your pet’s coat. Imidacloprid then stays in the oily layer of the skin and slowly releases provides month-long protection against fleas and ticks.

Seresto also has a unique mechanism which keeps active on your pet from rain or baths that can wash off other forms of treatments such as shampoos, dips or sprays. Seresto prevents parasites from attaching itself to your pet without biting so it doesn’t require flea biting before it starts working against all stages of fleas and ticks!

How Does it Work Without Biting?

The Seresto Flea and Tick Collar works differently than most treatments. Instead of merely killing fleas that bite, the active ingredients in the collar diffuse on your pet’s skin and coat forming a protective layer that prevents fleas from biting.

The collar also prevents existing eggs seresto collars and larvae from developing into adult boxwood fleas. This is known as a “stop-gap” solution because it doesn’t necessarily kill all of the fleas or their eggs present— but rather, it stops them from maturing and reproducing.

Seresto collars are made with two different active ingredients; an insecticide called Imidachloroprid, which paralyzes adult fleas and ticks upon contact, along with another insect growth regulator called flumethrin which kills larvae after contact. So without even having to bite your pet, these two ingredients prevent new generations of fleas from being born and protect your family from pesky nuisance pests.

How Often Should You apply Seresto?

The Seresto collar provides long-term protection against fleas and ticks, but how often you need to apply it depends on your pet’s lifestyle. Generally speaking, most pets should receive a new Seresto collar every eight months, however there are some factors that can influence this timeline.

If your pet lives mostly indoors or spends most of their time playing in the backyard, then an eight month window is reasonable. However if your pet frequents places like heavily wooded areas or areas known for high levels of flea activity, you might want to consider applying a new Seresto every five months. This will help ensure that your pet remains well-protected from any potential flea infestations.

In addition to environmental conditions, breeds and sizes of pets can effect the frequency of application as well. Pets with denser fur may need their collars replaced more frequently than those with short fur. Similarly, large dogs can benefit from a new Seresto application every six months while smaller dogs should stick with seven or eight months in between applications.

Final note

Even if fleas don’t have to bite for Seresto to work, it’s important to follow the instructions for use, such as making sure you cover all areas on your pet, and avoiding contact with humans. Regular monitoring will ensure optimal results too.
