Yes, Bifen IT can be applied to lawns for control of armyworms. You will apply 0.18-0.25 fl oz per 1,000 sq ft. Please refer to the product label for full mixing and application instructions for treating armyworms (Pages 14-15).
Yes, Bifen IT is labeled for roaches and will kill them. This product is not recommended if you have an active infestation of roaches. If you see an occasional roach, this can be used indoors and outdoors for control. The mixing ratio is 1 fl oz per gallon of water.
Also, please check out our Roach Guide for tips on how to treat and prevent roaches.
Bifen IT is labeled for cracks, crevices and wall voids only indoors, meaning that you could not spray it over carpeted areas or on furniture, the places that fleas are most likely to develop. Ultracide would be a great choice for indoor flea control. Ultracide contains both an insecticide to kill the active biting adult fleas and an IGR to help control developing flea eggs, larva and pupa. For most effective control, vacuum before treating and everyday for the next two weeks, be sure to change the bag or empty the reservoir immediately after vacuuming. A second treatment should be applied after 14 days.
Bifen IT should be mixed at 1 oz per gallon of water and sprayed 3 ft around a fire mound. You should also drench the mound by using sufficient force to break their apex and allow the insecticide solution to flow into the ant tunnels. For best results, apply in cool weather (65 - 80?F) or in early morning or late evening hours. The finished solution should also be broadcast over the lawn surface.
Bifen IT typically only take 1 hour to completely dry on a surface and will hold up very well in the rain, but the longer time you can have between application and a rain event the better. However, if a few hours is the best scenario then that is fine. Hopefully, you are in a situation where at least up against the house you may have a slight overhang from the roof or gutters so the application on and directly next to the house will be somewhat protected. Thank you for your kind comments about our products. We appreciate your business!
Yes, Bifen IT will kill chiggers and will work great when applied to areas where chiggers harbor. You will need to apply at a rate of 1 oz. to 1 gallon of water and focus your application on the unkept areas of the lawn and lawn edge.
We would not recommend mixing Bifenthrin and Permethrin together. The Bifenthrin mixed with an IGR is effective as well as mixing Permethrin with an IGR, such as NyGuard. Nyguard does have a residual for 4-5 months. With fleas, keep in mind that multiple applications are needed for them to be eradicated. After the first application, a follow up treatment should be done every 14 days until the fleas are gone.
Bifen IT will kill honey bees if they come in contact with the treated area and/or are sprayed directly. It is recommended that you spray in the areas you are wanting to treat when the bees are not actively foraging. A better option would be to use Mavrik Perimeter. There is no lingering odor or visible residue, and when dry, it is non toxic and non repellent to honey bees.
Bifen IT is labeled for fire ant control and will help help eliminate fire ants when used as directed on the Bifen It product label: Fire Ant control is optimized by combining broadcast applications that will control foraging workers and newly mated fly-in queens with mound drenches that will control existing colonies. If the soil is not moist, then it is important to irrigate before application or use a high volume application. Apply broadcast treatments at 0.5 to 1 fluid oz. per 1,000 square feet. Use enough finished volume to penetrate thatch or sod. Treat mounds by applying 1 oz Bifen IT per mound in 1 to 2 gallons water by sprinkling the mound until it is wet and treat 3 feet out around the mound. Use the higher volume for mounds larger than 12”. Treat mounds with sufficient force to break their apex and allow the insecticide solution to flow into the ant tunnels. For best results, apply in cool weather (65 - 80˚F) or in early morning or late evening hours.
