How Long Does Bifen It Last?

Bifen It has an active ingredient Bifenthrin which kills insects and pests by attacking their central nervous system. The recommended application of Bifen It is from one-fifth to ½ ounce of concentrate per gallon of water. The diluted mixture can be filled in a sprayer for even application. You can spray the insecticide in laws and gardens to control fleas, mosquitoes, ants and other insects. It can also be used inside residential and commercial properties to control a wide range of bugs, termites and pests.

Once applied, the formula lasts on the surface for up to six months if not washed away. It is a water-based insecticide that gets washed away with rain. If used properly, the residual effect can kill and manage pests and insects for several months without having to apply again.

Application can be repeated every 7-14 days if the infestation is severe. The low concentration of Bifenthrin means it is safe to use around pests and kids. However, ingesting the formula can cause severe adverse health effects.

How Long Does It Take For Bifen To Work?

Bifen is a broad-spectrum insecticide that homeowners can mix and use themselves to control a variety of pests, inside and out. You can mix ½ ounce of concentrate in a gallon of water for most insect-control spraying applications. If using indoors, you can get a sprayer and apply it along baseboards, around the cracks and crevices of doors and windows, behind appliances, in the corners and behind furniture.

Bifen does not kill on contact. It leaves a strong residual effect that works on insects and pests when they touch or eat it. Crawling across the insecticide exposes the pests to a fatal dose. It is also a repellent pesticide so it tends to repel insects. However, insects that continue coming across it get killed.

As it works with residual effect, it may take a few days to start killing insects you are targeting. Results can be seen after 24-48 hours of application. Bifen lasts for several months after application, controlling the infestation effectively.

Bifen It Vs XTS – How They Differ?

Bifen It and XTS are basically the same product with different concentrations of Bifenthrin. XTS has a concentration of over 25 percent which makes it three times stronger than IT. Both the insecticides can kill over 75 types of insects both indoors and outdoors. Though their active ingredient is the same, they differ in terms of application and features. For example, Bifen XTS is an oil-based insecticide which can stain on certain surfaces. It has a chemical odor but it is mild. It can be used mostly to treat outside areas.

Bifen It, on the other hand, is one of the most popular pest control products. It is highly preferred as a mosquito control formula. It is a less concentrated, water-based, odor-free solution unlike XTS which is sticky and high concentrate. It contains medium concentration of Bifenthrin to control and prevent a variety of infestations including termites. It also leaves a residual effect that works for months. It is also an excellent choice for perimeter treatment.

Bifen XTS can also be used to treat wood-boring pests and termites. It is a water-resistant formula that does not get washed away. It also works on ants, ticks, mites and more and can effectively manage infestations in commercial and residential areas. It also works as pre and post construction treatment. Overall, both these Bifen products are powerful and effective and you can choose the one that suits your type of infestation.
