The Best Flea and Tick Collar Reviews

1. Adams Flea and Tick Collar Review

The Adams Plus Flea and Tick Collar is one of the cheapest and the most popular dog flea collars. According to the product description, this collar provides protection against both fleas and ticks for up to 7 months.

However, depending on the rate of flea/tick infestation, you may need to replace the collar more often. If you have heavy flea/tick infestation, this collar might only work for one or two months.

To repel fleas and ticks, Adams Flea Collar uses active ingredients that include Tetrachlorvinphos (14.55%) and (S) -Methoprene (1.22%). The problem is that Tetrachlorvinphos can cause allergic reactions in some dogs and children.

So be sure to observe your dog for any signs of an allergic reaction like lethargy, vomiting, diarrhea, and trouble breathing. If any of those signs occur, stop using the collar immediately. And keep your children away from playing with the collar.

Customer Reviews:

Some dog owners reported that they need to use the collar along with Adams Flea and Tick Home Spray to get the best result.

But still, the combined price is lower compared to the other dog flea collars out there.

Customers also said that the collar emits a very unpleasant odor. This strong odor likely comes from the synthetic chemical ingredients that it uses.

Moreover, some customers found that the collar is too flimsy and is broken easily.


  • Low price
  • Seven-month protection
  • Water-resistant
  • Adjustable size


  • Mixed results
  • Strong artificial chemicals
  • Strong unpleasant odor

My Thought On Adams Flea and Tick Collar

I would not recommend this collar because of all the negative points that I had been listed. Plus, the use of Tetrachlorvinphos in the collar does concern me.

Bayer Animal Health Seresto FAQ

What are the side effects of the Seresto flea collar?

Seresto flea collar is composed of Imidacloprid and Flumethrin, two neurotoxins that target fleas and ticks. Referring to the laboratory studies being, Flumethrin is non-toxic to mammals and does not show any adverse side effects.

One the other hand, Imidacloprid can be slightly toxic and should only be used on the outside of your dog’s skin.

The Bayer Company itself has admitted that its collar may cause some side effects, including itchy skin, irritation, redness, fur loss, swelling, and intense scratching. Some dogs even experienced red eyes within the first few days after wearing the collar.

However, those side effects seem to be the case with almost all flea and tick collars made of chemical ingredients.

If you’re worried about your dog’s health being, it’s better and safer to choose natural flea collars.

In the first few days, you may want to start putting the collar on your dogs for a short period each day and see your dog’s reaction. If your dog shows any signs of an allergic reaction, discontinue the collar immediately.

How to Put on Seresto Flea Collar?

Putting on Seresto Flea Collar is quite simple, just put the collar around your dog’s neck and insert the loose end into the two loops. Read the instruction manual thoroughly before putting the collar on your dog.

How to Adjust a Seresto Flea Collar?

If the collar is too loose, you can trim off the excess length, leaving about 2 cm of the loose end beyond the second loop. The collar should not be too tight or too loose.

How Tight Does the Seresto Flea Collar Have To Be?

To know how tight the Seresto collar should be, you can use a rule called “the two-finger rule.” In this rule, you slide your pointer and middle fingers in between the Seresto collar and your dog’s neck.

The collar fits perfectly if you are able to sleep your fingers easily. If you can’t get your fingers in the collar is too tight, and if you can fit more than three fingers under the collar, then the collar is too loose.

3. Rolf Club 3D Flea Collar for Dogs

The Rolf Club 3D Flea Collar is a fast-acting flea collar that kills flea 24-48 hours after application. It provides six months of protection against fleas, ticks, larvae, and mosquitoes.

Who Should Use a Dog Flea Collar?

Dog flea and tick collars are an ideal choice for dog owners who prefer low-maintenance flea treatment methods as opposed to using tablets or spot-on style treatment, or for dogs who spend most of their time outdoors.

How Do Dog Flea Collars Work?

A dog flea collar is a regular collar with flea and tick repellents, which can be chemical or natural ingredients, added to it.

The collar releases and spreads the repellent into the dog’s system continuously over some time (5-8 months). The repellents then kill or prevent fleas from getting on your dog.

Since the chemical flea collar uses an insecticide, it is much more effective in killing fleas than the natural collar. But at the same time, the chemical flea collar is also more harmful to your pooch.

If your dog has an allergic reaction or is sensitive to insecticide, a natural flea collar is a better choice. The natural flea collar uses ingredients, such as Citronella oil, that smell bad to fleas. The collar does not kill fleas but only repel them, so you need to make sure that your dog is flea-free before putting on the collar.

How Effective Are Dog Flea Collars?

There are various reasons that can contribute to the effectiveness of the flea collar, like whether the collar uses natural or chemical ingredients and the stages of flea’s lifecycle.

During heavy flea infestation, flea collar alone won’t work. You need to combine the flea collar with other forms of flea control.

Use a household flea treatment products, wash or replace your dog bedding, and vacuum floors, furniture, and carpets often to get rid of flea eggs in your home. If the flea eggs are not removed, the flea infestation will not cease.

As for ticks, you should remove a visible tick manually or let your vet do it then use the flea and tick collar to help streamline the process.

Benefits of Using Flea and Tick Collars

Flea and tick collars offer three benefits compared with other flea and tick treatment methods.

The first benefit is that flea collars are incredibly low-maintenance and simple to use. It’s the set and forgets method; just put the collar on your dog and forget about it for three to eight months.

And the second, flea collars method is less expensive than spot-on treatment.

What To Look For When Picking a Flea and Tick Collar?

Here’s what to consider before buying a dog flea and tick collar:

1. Ingredients

The most important thing to look for is the ingredients that make up the collar. Are they chemical or natural?

Basically, chemical dog flea collar is more effective in killing fleas and ticks than their natural counterparts. However, the chemical collar also comes with some side effects that could potentially be harmful to your dog and children.

Here’re some chemical ingredients that are used in flea and tick collar:

  • Deltamethrin is categorized as one of the safest insecticides for humans. It’s considered safe to humans, but it’s highly toxic to fish.
  • Pyriproxyfen sterilizes females fleas and stops larvae from developing.
  • Amitraz is an effective anti-parasitic drug and is often used to treat mange too.
  • Propoxur kills fleas and ticks within 24 hours of application. But it’s highly poisonous to humans and might cause cancer in animals, though there is only limited evidence to support this.
  • Tetrachlorvinphos is an effective pest killer, but it also can be harmful both for humans and their pets.

2. Tick Protection

Make sure the flea collar that you are going to buy offers ticks protection as well.

3. Size and Adjustability.

Some flea collars offer adjustable one size fits all collar, and other collars have three different sizes for different sizes of dogs. Regardless of which collar you choose, make sure to measure the circumference of your dog’s neck first before buying.

If the collar offers three different sizes, and you don’t know which one to buy, you can buy the largest size and trim the excess length to fit your dog.

4. Protection Period.

Chemical collars usually offer a longer protection period than natural collars. If your dog doesn’t have any allergic issues, I would recommend getting the chemical collars.

5. Water Resistance.

All the collars in this review are water-resistant. This means you don’t need to worry if your dog is swimming, playing in the water, or out in the rain as the collar can stand up to soaking.
