Bio Spot Spot On Flea Treatment for Dogs Review


Keeping your pet flea and tick free is a dream for all pet parents, though it’s one that is rarely achieved. Pets like running around in the yard, in the park, and all the other places where they become easy targets for flea and ticks.

The good news is that you have tons of options to choose from to treat fleas and ticks and keep them at bay. The difficult news is the choice you have to make when it comes to decide the best for your pet.

We’ll help you along the process by telling you all about the Bio Spot Spot On.

Company claims

The Bio Spot Spot On is available for dogs. It’s a topical treatment that should be applied once a month and comes in a three month supply package.

The treatment claims to have an insect growth regulator that stops larvae from turning into adults and also prevents eggs from hatching.

This product is useful for treating fleas, ticks, and mosquitoes. It also kills larvae and eggs.

It prevents re-infestation for up to 30 days, though there’s no information available on how soon it starts killing insects.

How it works

The Bio Spot Spot On treatment kills deer ticks, adult fleas, and protects pets against mosquitoes. It also has a growth regulator that inhibits larvae from growing.

The treatment includes the following ingredients:

  • 45% Permethrin
  • 3.0% (S)-methoprene
  • 52% other ingredients

Permethrin is a synthetic chemical that is commonly used as an insecticide. It is a neurotoxin that kills insects by blocking neuron membranes. Though designated as safe for adult dogs, it’s toxic to cats. If you have both cats and dogs and opt to use a permethrin product, you need to keep your dog and cat separated for several hours.

(S)-methoprene acts as a growth inhibitor to prevent larvae and eggs from becoming adults. It is found in many spot on treatments.

Usage information

There is no available information on whether the treatment is waterproof. Some sources recommend that you shouldn’t bathe your dog for up to 24 hours after application.

Bio Spot Spot On is available online through licensed retailers and also in pet stores or larger supermarkets.

It can be used for puppies that are 6 weeks or older. There are specific formulations available depending on the age and weight of your dog.

Consult your vet before using on a pregnant, breeding, medicated, or aged animal.

Product warnings and side effects

Do not use Bio Spot Spot On near cats or fish as it is dangerously toxic to them.

Bio Spot Spot On has low toxicity for humans and is usually not absorbed by skin. While it’s safe to use, it should be kept out of reach from children.


Pet owners are divided on this; some people love it, others not so much.

Our take – try it and see if it works for your pet but if you have cats, you may want to try something else first.
