What’s the Best Way to Kill Fleas?

If you own a cat or a dog that goes outdoors, then you probably must have wonder; can pet transfer fleas to humans?, since it has a good chance of bringing insects inside. One flea soon turns into an infestation that leads you to wonder, “What’s the best way to kill fleas?” It actually involves several steps.

Are you like I once was in thinking that you just need to treat your pet to kill fleas? Do you know that a vacuum is a good insect killer? Do you want to know about pet treatments?

Killing Fleas Involves More Than Just Treating Your Pet

As pointed out by the University of Kentucky Cooperative Extension Service, killing insects not only involves exterminating adult insects, but also handling the 50 eggs laid each day by one female flea, the resulting larvae, and pupae, which are often resistant to insecticides.

So, not only do you need to kill the biting, adult fleas hiding out on you and your pet, but you must treat your home, too, where over 90 percent of the future fleas are hiding out in the form of eggs, larvae, and pupae.

The first step is to remove all stored items, clothing, and toys from closets, under beds, and on the floors in order to treat your home. Remove pet bedding and either destroy it, or wash it with very hot water, which kills all forms of the flea life cycle within the bedding.

Next, diligently clean your entire home with a vacuum. Ohio State University researchers discovered that an average of 96 percent of adult bugs, all larvae, and all pupae were killed after going through an average home vacuum cleaner.

Even though most forms of fleas die, toss the vacuum bag, or the contents of a bagless vacuum, into a sealed bag, and throw it away in the outside garbage receptacle. The whole idea is to completely eliminate all traces of fleas, including adults, eggs, larvae, and pupae. This is definitely one of the better ways to get rid of fleas in your home, only a few more options would work in an insect infestation.

Why It's Best To Use Insecticide in Your Home

After a thorough cleanup, insecticide should be applied to your home once all people and pets, except for the person applying the chemical, are removed from the premises. Reentry into the home shouldn’t begin until the pesticide is dry, which might take hours on carpets.

Selection of a tick insecticide should include a chemical killer for adult fleas, such as permethrin, and insect growth regulators to control tick eggs, larvae, and pupae, such as methoprene and pyriproxyfen, and Siphotrol® Plus II Premise Spray contains these items.

Understand that permethrin is deadly to cats, which is all the more reason why you must remove all pets from your home while spraying. Once the pesticide is dry, there is no longer a chance of harming pets or human occupants of your home.

An aerosol design is easier to dispense, since locations under beds and behind furniture is effectively covered with an aerosol version of the insecticide, plus this type of application is more directed than flea foggers, which spew insecticide unevenly from the room’s middle.

Be thorough when using this spray and carefully cover locations where pets sleep and spend time, such as under the bed where the family cat sleeps, making it an area needing particular attention with your can of spray.

Don’t be surprised to see additional ticks for two weeks after your initial treatment, coming from the earlier life stages of the insect, and if a new bug infestation occurs, simply retreat your house, and possibly your pet, to eliminate the final stages of the flea incursion.

While treating your home, you also need to kill fleas on you and your pet.

Kill the Fleas on Your Pet

Fleas hate water, so an effective way to eliminate insects on your body is to take a twice daily shower, complete with vast quantities of soap that you usually use, since special soap is unnecessary.

Bathing your dog or cat is also effective as an initial step in treating fleas on your pet. You don’t need to buy an expensive tick shampoo or soap, since Dawn® Dishwashing Liquid works good, and it doesn’t harm your pet, but kills insects by dissolving their exoskeletons.

Watch this YouTube video to see what to expect in the form of the red color of the resulting wash water while bathing a kitten with the dishwashing liquid.

Next, administer a good flea insecticide on your pet, such as Advantage® II Flea Treatment for Cats, or Frontline® Plus Flea and Tick Control for Dogs, which both come in dog and cat formulas.


The best way to kill fleas in your home is to vacuum your home, wash pet bedding, and then do the following:
