Generally, after an application of Bifen IT it should take a few hours to dry outside, typically 4-6 hours.
Bifen IT will not affect your trenching treatment done with Termidor SC. Bifen I/T is considered a repellent. When treating for ants, you can spray the lawn, trees and shrubs, along with 3 foot up the side of your home, 3 feet out into the soil all the way around the perimeter foundation of your home, around doors and windows and around the eaves and soffits of your home monthly.
Although Bifen IT is considered a repellent insecticide, it is not a true repellent in that it “repels” insects away. Insects will still be able to contact the treated surfaces and eventually die from through contact of the active ingredient. Bifen IT is included in our Silverfish Kit that you can view HERE.
If wanting a non repellent insecticide, Temprid FX is a dual mode of action inseciticide using 2 active ingredients, one providing a fast kill and then a non repellent residual to go undetected as insects cross the treated areas.
Please view our Silverfish Treatment Guide for more information and product recommendations for a complete treatment program.
Bifen IT cannot be used in animal grazing pastures. Essentria All Purpose Insecticide Concentrate can be used in animal grazing pastures for ant and tick control.
Bifen I/T is one of our most popular products for mosquito control. Bifen XTS is basically the same product, just in a higher concentration, and oil-based instead of water-based. Either sprayer or mister application would be effective with either product as long as the application is thorough. Oil-based products such as Bifen XTS can stain some surfaces. This is not usually a concern in most areas outside, but you should use caution when treating around the siding of a home. Most oil-based products such as Bifen XTS do have a "chemical" odor but it is not especially strong.
Do not spray any bifenthrin product in a way that would contact the pond with direct spray, drift, or runoff.
Mosquitoes lay their eggs in standing water, so if there are any areas of standing water where you are treating, those should be treated as well with Altosid Pro-G Mosquito Larvicide if you prefer not to use BTI Mosquito Dunks.
Yes, Bifen IT can be used to treat fire ant mounds directly as well as broadcast over the lawn. Please view our How to Get Rid of Fire Ants Guide for step by step instructions and a helpful video.
We have not heard any feedback on Bifen IT becoming gel-like when mixed as directed on the label. Make sure you are shaking the concentrate well before tank mixing, and agitate thoroughly before and during applications to ensure that the mixture has gone into solution. You can also contact the manufacturer Control Solutions for additional support by visiting their website's contact page here.
We would recommend applying a product like Bifen IT in our Chapin Slide Pump Sprayer. This sprayer will reach well over 30ft. We do not carry any products that can be applied in a pressure washer for this type of insect control. You will mix the product at 1 oz per gallon of water per 1,000 sq ft monthly on the exterior. Please let us know if you need anything else.
