Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Questions & Answers

3 Customer Questions


Is this effective on lice?
Answer by ChewySep 13, 2019
This treatment works to kill and repel fleas–including eggs, larvae and pupae, ticks, mosquitoes, chewing lice and biting flies.

Do you carry effetix for dogs in the 15# range?
Answer by ChewySep 27, 2018
This also comes in a small dog formulation for dogs weighing 5-22.9 lbs.

Can I use one of these if my dogs have been on Vectra?
Answer by ChewyMay 21, 2018
This treatment is strong enough to be used alone. We recommend consulting a veterinarian before mixing flea and tick treatments.

Does the job

With a good flea bath before hand, I have had no problems with this on my 3 pomeranian.

Good stuff

I've used this product for almost 6 years now. We have a variety of sizes of dogs from 5lbs to 40lbs. If administered properly it is FANTASTIC! We got a real bad tick infestation one year and within a month of using this there were no more! Remember always wait 72 hours before or after any baths before using. Also make sure you part the hair ALL the way and get it right on the skin. If not then it won't work.

Effitix Plus

I just got my Effitix Plus last week, and I was shocked. It worked so fast getting fleas off.I had ordered regular Effitix last year and was pleased with it, so I ordered again, but this time from Chewy.com. For the weight of my dog, they only had Effitix Plus, so I ordered it, and it is amazing how good it worked. I am very happy, and the price was cheaper than where I ordered before. Good product and great prices. How can anyone go wrong? Thank You Chewy.com

This didn't work at all on my dog. I'll try again next month after his flea bath.

Actually works

Dries fast and doesn’t stink and actually work they use this at the animal shelters. Just make sure to put it on and wait 2 days before you bath your dog if not it won’t work. Gentle and doesn’t cause irritation to my dogs and they have sensitive skin.

Has short lifespan

This product will those work has a short lifespan I gave this product to my free small dogs then I wash them with medicated shampoo I bought from this website and they were flea free. 2 Days Later... they had fleas on them again I do not have carpet anywhere in my house nor do I rarely let my dogs outside. I wash my beds and couches regularly as well. I guess I just need a stronger medication that actually works.
