Top 5 Best Flea and Tick Treatment for Dogs & Cats – Reviews

I'm sure most pet owners would agree with me that fleas are just the bane of our pets' existence! They're so difficult to get rid of and can potentially cause a lot of health impacts for us and our pets. Fleas tend to be a lot more common during the warmer seasons so I thought I'll write up a little post to share my top recommendations for flea treatments.

Understanding More About Fleas

Here are some quick points to help you understand more about fleas so you can better understand how to tackle them.

  • Fleas have a compressed shape to help them run through the hair/fur of pets really easily.
  • Scratching is not the only sign of an infestation! In fact, some pets might have a major infestation going on but don't scratch (either because it's not allergic to fleas or doesn't have very sensitive skin). Don't take for granted that your pet not scratching means you're not facing any flea infestation!
  • Fleas take a month to grow from an egg into an adult.
  • Can you just use cat flea products on dogs and vice versa? The answer is no. There are different ingredients in the products that are meant for different pets so be sure to stick to the instructions.

No time to read? My Top Recommendation

Bayer Advantage II Flea Control Treatment for Cats

I find this to be the most effective; even after your cat swims or has a good old shampoo. Safe for kittens and cats from 8 weeks old and above.

Bayer Advantage For Dogs

Easy to apply and extremely effective, Bayer Advantage uses imidacloprid as its main ingredient to cause paralysis and death to fleas. Its 2nd main ingredient stops eggs from hatching. This is the best flea treatment for dogs in my opinion.

Finding Fleas on Your Pets

You can look out for a few signs, one of them being flea dirt. Flea dirt is reddish brown in color so you can wet a paper towel and then rub the moist towel on some spots of your pet. If there is the presence of flea dirt, you'll see signs of a reddish brown color on your moist towel.

Another way is to thoroughly examine with good light through your pet's hair. It is difficult but absolutely necessary if you really want to spot the problem and presence of fleas so you can eradicate them quickly.​

Check your carpets for any sign of flea eggs. Using your hands, run through the carpet fibers and if you spot small ovals that are white in color, chances are they are flea eggs. Using a magnifying glass will help you tremendously.

Another way to check for fleas is to attract them with some heat, light and water. Put some warm water into a bowl and add a little liquid detergent to it. Placing the bowl of water on the floor, position a lamp over the bowl so the light shines over it. If there are any fleas in the vicinity, you can be sure they'd be attracted to the light and jumping into the water where the soap will kill them.​

Pets often get infested with fleas as they come in contact with other animals or even in contact with the fleas in the environment. You need a proper flea treatment to help your pets be safe. So, what are the treatment options and how can you save your pets this season? Here’s a look at the different flea treatment control products for dogs and cats.

Flea Treatment For Cats

Protecting your pet is easier than it sounds. If you are interested in knowing how well cat flea collars work, do read my post here. Dealing with your pet’s flea issues early on and save you a whole lot of hassle! Don’t wait for the problem to compound and get out of hand.

When flea medication doesn’t seem to work on your pets

Some pet owners often share their experience in treating their pets’ fleas and ticks consistently, yet get disappointed that after all they’ve done the bugs still won’t go away. It could be frustrating especially if you’ve already spent a lot for the products. But it’s really not just about the effectiveness of anti flea and tick products. There are many reasons why fleas continue to exist. It’s necessary to stop the infestation.

To start with, ensure that you are effectively applying the treatment. It’s all in the application. This is true when it comes to topical products like shampoos. It is vital to totally part the hair and apply the treatment exactly to the skin for proper skin and hair follicle distribution. This is quite challenging for thick haired pets. The treatment won’t work legitimately if only the hair follicles get into contact with the treatment – it must reach your pet’s skin so the skin can absorb it. It’s absolutely essential to follow directions from the product instructions. For example, for big dogs, Advantage II requires the treatment to be spread on various spots down the back of the pet. Proper application is so vital.

While it is enticing to attempt and spare cash by using treatments marked for big pets on smaller ones, this can only prompt ineffectiveness of the product. Again, make sure to follow the product’s direction for use and only use it for the specified type of animal. Never use dog flea treatment on cats.

Another possible reason behind these products not working is by not treating your home and yard, where eighty percent of the flea’s life cycle may happen. It’s very important to get rid of fleas inside and outside your home. This will prevent fleas and ticks from coming back after you have treated your pet.

In instances of overwhelming infestation of fleas and ticks, try using products that can dry out their life stages. Banish all fleas and ticks once and for all by investing on these products. Make sure to use non toxic flea infestation solutions for your pets and for your home. Treating both your pet and your home will prevent reinfestation. There are many other ways to get rid of fleas. Just make sure they are safe for you and your pets.

Lastly, be patient as it will take some time to get rid of those fleas. As long as you do it correctly and persistently, you will get results.
