When treating exterior foundations, siding, around windows, doors, etc using Bifen IT at the advised labeled rate of 0.5 to 1 fl oz per gallon of water, there should be no staining, discoloration or visible residue. Make sure you are shaking the contents of the sprayer when mixing and during the application to ensure the insecticide is completely suspended throughout the water, especially as the mixed solution gets low.
Per the Bifen IT product label: Bifen I/T will not discolor or otherwise harm surfaces that water alone will not discolor or otherwise harm
Bifen IT is labeled for grasshoppers. Please be sure to carefully read the product label for specific application instructions.
Avid 0.15 EC Miticide Insecticide (Group 6 Insecticide) can be used in rotation with Bifen IT (Group 3 insecticide) for Spider Mite control.
Avid 0.15 EC Miticide is should be applied for 2- 3 applications at 7 day intervals at the product label rate of 4 fl oz per 100 gallons of water (0.24 tsps per gallon of water) before rotating to Bifen IT for 2 to 3 applications at 7 day intervals at the rate of 0.25 fl oz to 0.5 fl oz per gallon of water per the product label.
Bifen IT cannot be used in ULV, Thermal or Propane fogging equipment and only labeled to be used in a pressurized hand pump sprayer, backpack sprayer or gas powered mist blower that provides larger droplets.
Please view our ULV Fogging Solutions and Thermal Fogging Solutions for products labeled to be used in fogging applications.
Please view our Mosquito Treatment Guide for more detailed information.
Bifen IT could possibly kill hoverflies if they contact a treated area long enough to receive a lethal dose. Hoverflies are actually beneficial insects that feed on other insects that might attack plants. They also are pollinators that help your flowering plants. We apologize that we do not offer advice/products for killing beneficial insects.
For Armyworm control, Bifen IT is applied at 1 fl oz per gallon of water per 1,000 sq ft with repeat applications done every 30 days.
Please view our Armyworm Treatment Guide for more information.
Bifen IT should only be applied to interior cracks and crevices quarterly (where floor meets the wall) and monthly to listed exterior areas as directed.
The Cypress trees will not be affected by Bifen IT when used as directed, it is known for being super gentle on plants. It is safe to spray onto those areas, and may return once product has dried. If your friend is applying the product, we encourage them to wear long sleeves, long pants, and a face mask to protect them while spraying.
We recommend performing a jar test to ensure they are compatible and test a small inconspicuous area prior to treating a larger area.
Bifen IT should be applied once monthly to the lawn or the Bifen L/P Granules once every 2-4 months as directed. Either formulation can be used as long as appropriate rates are used.
Bifen IT can be used to treat around potted or containerized plants outdoors.
Bifen IT cannot be applied to pet bedding and not recommended for active infestations of fleas/ticks indoors. Bifen IT can be used outdoors for fleas and ticks in lawns, bushes, trees, shrubs and landscape beds.
The Indoor Flea & Tick Kit would be the best treatment for fleas and ticks indoors. The PT Alpine Flea Aerosol can be applied to pet bedding, carpets, rugs and other resting areas. Once dry, it is safe for pets to lay on the bedding.
Bifen IT is applied at 0.25 fl oz- 0.5 fl oz per gallon of water per 1,000 sq ft. NyGuard IGR is mixed at 4ml to 8ml per gallon of water per 1,000 sq ft . These two products can be tank mixed in a handpump sprayer, backpack sprayer or mist blower. Fill the tank 1/2 way with water, add the recommended rate for the insecticide/IGR you are using (Bifen IT / NyGuard IGR), shake the solution and then fill the tank the remaining way with water. Tighten pump handle and shake sprayer solution again.
Yes, once the application of Bifen IT dries, water will not reactivate the product.
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.
A better option than mixing Dominion 2L or another product with Bifen IT would be switching to a different product. Alpine WSG would be a great product to rotate with Bifen IT since it is a different class of active ingredient. Another great option is Temprid FX, which has imidacloprid (which is in Dominion 2L) plus beta-cyfluthrin.
People and pets should be kept out of the area until the application of Bifen IT (or any insecticide) has completely dried. This can usually take 1-2 hours. Once dry, it is safe to reenter the area.
Bifen I/T is a concentrate that can be used in tank sprayers or hose end sprayers, as long as the hose end unit has a dial to select the correct mix rate. The Bifen Product Label states to use anywhere between 0.5 and 1 oz per gallon of water dependent on the pest you are treating for and severity of the existing population. This means you can choose either of these settings on your dial of your hose end sprayer, and that is the amount of concentrate it will pull and disperse per gallon of water.
Only the applicator should be present during the application of Bifen IT until everything has dried completely and then others can return. You can treat the exterior once monthly and quarterly to interior cracks and crevices.
Bifen IT can be used as a trench method of termites directly around the foundation for Subterranean Termites and will provide a 1 year barrier protection. Application rates for Bifen IT are 1 fl oz per gallon of water using 4 gallons of mixed solution every 10 linear feet in a 6 in x 6 in trench.
For Termite Trench Treatments, a better product would be Taurus SC as this product lasts in the soil for 10 year barrier protection against termites. Taurus SC is applied at 0.8 fl oz per gallon of water with using 4 gallons of mixed solution every 10 linear feet in a 6 in x 6 in trench.
