Sergeant's Evolve 61 Flea and Tick for Dogs Review

Sergeant’s Evolve 61 Flea and Tick for Dogs Review


Are you looking for an effective, inexpensive flea and tick treatment?

The problem is that monthly flea treatments can get expensive and many of them don’t even work. Some can actually harm your dog.

Relax because we’re here to help you out. Today we’re going to take a look at Sergeant’s Evolve 61 in order to decide if the product is safe and effective. We’ll take a look at the ingredients and see what real-life users have to say about it so that you can make an educated choice regarding your flea control program.

Company Claims

The claims for this product are fairly simple. They claim that their product kills the following in as little as an hour:

  • Fleas
  • Ticks
  • Larvae
  • Flea eggs

They also claim that the product is waterproof and controls re-infestations. It supposedly works for 20 days and is effective in as little as 3 hours.

The treatments comes in a 3-month supply packaged in individual doses for small and medium dogs.

Active Ingredients

  • Cyphenothrin 30%
  • Pyriproxyfen

How it Works

Both of these are the same ingredients that are found individually in many other OTC and prescription flea treatments. Cyphenothrin is a neurotoxin that causes seizures, paralysis and then death in parasites.

Pyriproxyfen is a growth inhibitor that keeps the larvae and eggs from maturing so that they can’t bite and breed.

Both ingredients are used with relatively safety in other flea and tick products, which makes the user comments a bit confusing but crucial.

What Are Users Saying?

It should be noted that other Sergeant’s products aren’t causing this reaction. For that matter, there are other Evolve products with different ingredients that seem to be just fine. There aren’t any mass warnings out about either of the active ingredients, either.

Regardless, the complaints can’t be ignored.

The price is extremely competitive at $8 or less per dose.

Usage Information

Apply between the shoulder blades of your dog and allow to dry for 24 hours before bathing. Reapply every 3 weeks if you choose to use it.

Product Warnings and Side Effects

We’ve already discussed the user complaints but strangely enough, the box doesn’t say anything about any of those reactions.


We don’t recommend using this product under any circumstances. There are many other safe products out there to use something that obviously has a glitch that is affecting the health of an unusually high percentage of users. Click here to find flea drops that are both safe and effective.

    I did not research this product before using it and wish I had! I put it on two of my Shih-Tzu’s and it caused chemical burns on their skin. They have been twitching, scratching and crying. It is awful. I have been up bathing them with hydrocortisone shampoo and giving them Benadryl for past two days. DO NOT USE EVOLVE FLEA DROPS ON YOUR DOGS! I am at a loss to understand why this product is still on the market, it is extremely dangerous and should be banned!

    THis product is horrible, I have tortured my Chihuahua. I would NEVER buy this or any other Sargeant product again. Cant believe all the negative reviews I have read and still this product is on the market. Company should be sued and/or their name should be dragged all over the press ie. Ellen…..

    I put this on my 11 year old boxer…Oh, I have made a horrible mistake, 24 hours after I applied it, he began quivering, acting very confused, erratic behaviors. He cannot get comfortable. He is very anxious. I am taking him to the vet today with the remainder of the EVOLVE, hopefully the vet will guide me on the proper way to get my dog comfortable again and proper channels to report this med and side effects.
