Keith's Pro Tips

"Worried about spraying Bifenthrin insecticides on your plants? Don't be. Because plants can't absorb Bifenthrin, it's safe to use it on ornamentals and turf."

Bifenthrin

For an insecticide to be effective, a powerful active ingredient is needed to both quickly kill the problem pest and provide a residual effect so you don't have to apply it so often to maintain control. One such active ingredient that achieves these qualities is Bifenthrin and it does so against over 70 different common household pests.

Bifenthrin is an important active ingredient in a number of the professional-grade insecticides we have at Solutions Pest & Lawn, including our popular Supreme IT formula which we exclusively produce at our manufacturing facility.

Here you can learn more about this potent pyrethroid and effective active ingredient and shop the various bifenthrin based products we have in our stores.

What is Bifenthrin?

Bifenthrin is a pyrethroid insecticide used to control over 75 different pests by influencing the target pests nervous system. It is a synthetic pyrethroid meaning that it mimics the qualities of pyrethrum, which is naturally derived from the chrysanthemum plant.

Although it is listed as a restricted-use chemical in the United States, it is allowed to be sold for daily use, provided the product sold has a low concentration of Bifenthrin. The chemical was originally discovered and developed by the FMC corporation.

First introduced in 1983, Bifenthrin is a broad-spectrum insecticide, miticide, and termiticide. These insecticides are used indoors and outdoors to control many pests, like ants, termites, cockroaches, ticks, mole crickets, stink bugs, armyworms, and many other invasive, turf, or ornamental pests as well. Bifenthrin is available in flowable formulations for general pest control and termite control and granular formulations for general outdoor pest control.

How Does Bifenthrin Work?

Mode of Action

The mode of action of Bifenthrin is similar to other insecticides on the market in that the chemical targets insects by paralyzing the central nervous system upon touching the chemical or ingesting it. This paralysis creates an inability to function or eat which eventually leads to the pests death. It can take minutes to several hours for a pest to die.

When allowed to dry on a surface, Bifenthrin will leave a long-lasting residual that will continue to control pests for a duration, typically several months. It is a white waxy solid with a faint sweet smell. It is chemically synthesized in various forms including but not limited to: powder, granules, and liquids. However, it is not naturally occurring.

Benefits of Bifenthrin

The best thing about Bifenthrin-based products like Supreme IT and Valar Plus Bifenthrin Granules is their residual effect. The product remains effective for a long time, for up to 90 days. This means that you don't have to re-apply the product as often. A quarterly application of either product can keep pests off of your property all year long.

Bifenthrin is best used for both indoor and outdoor applications for a variety of different pests. You can safely apply the product where food is handled and in cracks and crevices where pests can hide and breed.

Drawbacks of Bifenthrin

While Bifenthrin is an effective active ingredient, it does not provide an instant kill. Exposed insects may take 10 minutes or so to die from the effects of Bifenthrin.

Avoid using Bifenthrin-based products when you want to treat insects that are damaging fruit-bearing plants, vegetables or flowers.

How To Use

Bifenthrin products usually come in a liquid concentrate which will need to be mixed with water in a pump sprayer. It could also come in granule form and would have to be applied using a granular spreader or a special container that it is packaged in.

If you are looking for versatile, broad-spectrum pest control, then we recommend you use a product like Supreme IT. Supreme IT is an insecticide concentrate made with 7.9% bifenthrin. Use Supreme IT indoors and outdoors to treat pest infestations or prevent them from breaking out.

Spray Application

First, you should measure your yard's square footage to determine how much of the Bifenthrin-based product you need. Following the label instructions of the product, mix the appropriate amount of the Bifenthrin product into your selected sprayer with water and then apply the product to the areas where you wish to treat for insects.

To treat most pests with Supreme IT, you will mix up to 1 whole fluid ounce of product into 1 gallon of water to apply evenly over 1,000 sq. ft. of treatment area. Once your solution is mixed, you can apply it as a broadcast spray, barrier spray, and into cracks and crevices. Spray around baseboards, around winter pipes, around doors and windows, and behind and underneath appliances.

You can apply this product over lawns, ground cover, shrubs, flowers, non-bearing fruit and nut trees, and exterior structural features such as around doors, windows, eaves, utility penetrations, external lighting, or any other voids leading into the structure. For broadcast spraying, surface spraying, or barrier spraying, use a fan-nozzle spray setting to get uniform coverage. For crack and crevice spraying, use a pin-stream nozzle setting for precise application.

Pests that make contact with the spray or its residual will have their nervous systems impacted and will die within hours. Supreme IT will leave behind a residual that will last for up to 90 days.

Granular Application

Applying Bifen LP

If the Bifenthrin bait comes in granular form, you may need a spreader to apply the product or can shake it out of the container it comes in. Load the appropriate amount of granules into your spreader and then broadcast the granules evenly over the treatment area. Afterward, you can water the treated area to help the granules penetrate the soil.

If you are looking to just treat pests in your lawn, then we recommend you use Valar Plus Bifenthrin Granules. Valar Plus Bifenthrin Granules is a granular insecticide made with 0.2% bifenthrin, so we recommend you apply this product with a broadcast push spreader. Depending on what pests you are targeting, you can apply 1.15 to 4.6 lbs. of product per 1,000 sq. ft. of treatment area. Once you have completed the application, water the product into the soil with at least 2 gallons of water per 1,000 sq. ft. of treatment area.

Turf pests like armyworms, mole crickets, or other pests on the product label that travel through the grass or soil will come into contact with the active ingredient and die. Valar Plus Bifenthrin Granules will control turf pests on your lawn for up to 3 months.

Is Bifenthrin Safe?

Yes, Bifenthrin is a safe chemical to use around your home and yard. Bifenthrin is a synthetic pyrethroid, which is the man-made version of the natural pesticide pyrethrum which is made out of extractions from the chrysanthemum flowers. People in the pest control industry often refer to pyrethroids as the insecticide that is safe as chrysanthemums.

However, Bifenthrin has demonstrated that is can be somewhat toxic to birds and highly toxic to fish. Bifenthrin is not harmful to your pets when the product application has dried. Bifenthrin is also safe to use in your yard because it cannot be absorbed by plant foliage.

When applying Bifenthrin, as you should with any other type of pesticide, always exercise caution and put on protective gear before handling chemicals. This can include gloves, a protective mask, and long sleeve clothing.

What To Expect

When using a Bifenthrin-based product, you should expect a significant reduction or total elimination of your insect problem in little time. Bifenthrin, though not an instant killer, does kill insects quickly and leaves a long-time residual which can last up to 90 days, meaning you don't have to reapply as often unless you have a very heavy infestation.

Quarterly applications of Bifenthrin-based products will provide continued control of target pests all year long.
