We have prepared this detailed buying guide to help you navigate through all you need to know about buying the best flea meds.

What Are The Types Of Flea Medication?

Oral flea treatment

This type of flea medication comes in form of chewable or pills and can be ingested by your pet. When an adult tick bites your dog, the medicine is transmitted to the tick, killing it. There are some important active chemicals used in producing flea and tick medications.

Some of these active chemicals may last a month while others may only last for a few days. Some of the active chemicals you should look out for when buying oral flea meds are:

Nitenpyram

This chemical is a fast-acting insecticide that kills adult fleas in thirty minutes. This active ingredient is mostly used by vets to kill fleas quickly. It does not have a long-term effect, so it should not be used for continuous flea control. Any pill or chewable that contains nitenpyram kills fleas and ticks swiftly are approved to be used on cats and dogs by the FDA.

Lufenuron

This chemical unlike nitenpyram does not kill adult fleas. It is more effective at killing any larvae produced by adult fleas. It does not kill ticks as well. The Food and Drug Administration (FDA) approved this compound as safe to be used for both dogs and cats. You may want to buy medications that contain both lufenuron and nitenpyram.

Spinosad

This compound only kills adult fleas, it does not kill ticks. When fleas bite the skin of your dog, the chemical overstimulates the flea’s nervous system, killing it in the process. Any medicine that contains the spinosad compound is not recommended for dogs with epilepsy. Spinosad is approved by the FDA to be safe for flea treatment.

Topical flea treatment

Topical flea medication is also known as “spot-on” medications. This type of treatment is generally applied between the pet’s shoulder blades, and back so the pet cannot lick it off. Some topical medications may last for months, while others may last only for a few weeks or even days. Some topical medications not only kill fleas and ticks but also repel them and prevent re-infestation.

The best topical flea treatment is one that is waterproof. Topical treatment is more effective than oral pills; fleas don’t have to bite your dog before they die. Upon contact with the treatment, it kills them in minutes. There are some important active ingredients to look out for when buying the best topical flea treatment.

Fipronil:

This compound works by overstimulating the nervous system of fleas and ticks, killing them in the process. This chemical spreads over your dog through body oils in about a day, killing everything in its path. It usually lasts for about and month is approved to be used on cats and dogs by the Environmental Protection Agency (EPA).

Imidacloprid

This chemical kills fleas by attacking the nervous system. Upon contact with your pet, it kills fleas at all life stages; both adult and larvae. It is approved safe to be used on both cats and dogs by the Environmental Protection Agency.

Pyrethroids:

These compounds are also called pyrethrin. It is an organic compound derived from a flower. This makes it really popular among dog owners who are more environmentally conscious. Pyrethroids can also be manufactured. These synthetic types are more effective and last longer.

This compound should not be used on cats and should be used carefully on small dog breeds. It is extremely toxic for felines, so be extra careful if you have a house full of cats and dogs. Pyrethroids are effective in killing fleas, ticks, mites, and other parasitic critters.
