Bifen IT - Questions & Answers

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 should only be applied to interior cracks and crevices quarterly (where floor meets the wall) and monthly to listed exterior areas as directed. 

When using Bifen IT for armyworms irrigation is not necessary. You actually need to try to have no irrigation or rainfall for at least 24 hours after the application. Under chinch bug treatment it does advice that in order to optimize the penetration of the insecticide you can water the area prior to the treatment. If grass is being kept at a long mowing height or if the thatch layer is excessive, use higher volume treatments. It may be necessary to use higher application rates (up to 1 fluid oz. per 1000 square feet) to control populations made up of both adults and nymphs in mid-summer. Complete instructions are on the product label for each pest as well.

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.

Bifen IT  is labeled for Indian Meal Moths, however, we do not have a product that is labeled to be sprayed in the actual fireplace. You may spray outside edges and surfaces of the fireplace but not inside or in the chimney/flute areas. 

Moths are attracted to light sources, including fireplaces therefore it’s a common access point for them to enter the home. An easy way to eliminate Indian Meal Moths in a fireplace would be to simply light a standard to good size fire and let it the fire burn for atleast 20-30 minutes. Heat temps between 120-140 °F is hot enough to kill Indian meal moths. 

We would recommend reviewing the Indian Meal Moth Treatment Guide for alternative product recommendations and more helpful tips.

Bifen I/T can be used for mound drench application on fire ant colonies in the yard as well as broadcast spraying over the surfaces of the lawn.

Per the ant control and mound drench instructions from the Bifen I/T Product Label:
The best control will be achieved by using broadcast treatments in combination with mound drenches. This will control present colonies along with foraging workers and newly mated flyin queens. It is critical either to use high volume treatments or to irrigate prior to application if the soil is dry. Apply 1 fl. oz. per 1,000 square feet when using broadcast treatments. For mound drenches, dilute 1 teaspoon of Bifen I/T per gallon of water and use 1 to 2 gallons of finished dilution using sufficient force to penetrate the top and allow dilution to flood ant 39 channels. Treat a four-foot diameter around each ant mound. 

Application should be made in late evening or early morning when it is cooler (65

Bifen IT is labeled to be used in poultry houses and chicken pens so it should not harm your chickens even if they eat the grass or bugs.  The small amount of active ingredient is only enough to kill a small insect.  You must make sure your chickens are out of the area while you apply Bifen and then they can return to the area as soon as it is dry. Keep in mind that this product cannot be broadcasted where chickens wil graze. 

Per the product label, the soil around a well can be treated with Bifen IT as long as you are following the instructions. It is recommended to keep applications at least 10 ft away from the well. Please be sure to review the product label for more information before use. Pages 11-12 give specific instructions for treating around wells.

Bifen IT cannot be used in a fogger, can only be used in a mister/sprayer. We do not recommend fogging as there is no residual behind fogging.

No, Bifen IT is a water-based product and is not labeled for use in foggers of any kind.

Bifen IT is not permitted to be used in a ULV or a thermal fogger.  Bifen IT is only permitted to be used in hand pump sprayers/mist blowers or gas-powdered sprayers with larger droplets.  Bifen IT can clog foggers

Bifen IT cannot be used in pastures where animals graze. If there are no grazing animals, let us know what you are treating for, for specific rates. 

Bifen IT is labeled for "weevils" in general and the active ingredient Bifenthrin is known to be effective for white pine weevils. It is important when using a foliar application that treatments start when adult weevils first start to appear in spring, usually around mid-April. At this time, Bifenthrin seems to be the only active ingredient available to homeowners for white pine weevil control. We also suggest you contact your local cooperative extension office for more tips on the best treatment time in your specific area.

Unless the plants were actually sprayed you do not have to worry. Bifen IT does not move through the soil or turn into a vapor of any sort.

Bifen IT would be a sound choice for exterior insect control. Bifen IT lasts for up to a month outdoors and is labeled for over 75 different crawling and flying insect pests.

That's awesome Bifen IT has been doing such a great job for you. To treat the Earwigs, please refer to our article Getting Rid of Earwigs. There are many steps you can take to treat and prevent earwigs and Silverfish. By following the steps in our article you will also help to eliminate the Silverfish as well. You also may want to try a residual spray like Demon WP that is labeled for earwigs and silver fish. You want to spray the entire perimeter indoors and out.

The Cy Kick CS you have been using is a great product for Scorpions but we do understand the need for more cost effective options. You want to go with a product that will sit on top of the surface better than the Bifen IT. If you dont have any dark surfaces to treat, you could use a product like Cyper WP. It is a wettable powder you would mix with water and spray in the same manor you would the Cy Kick CS. A 1lb jar will yield 24-48 gallons of mixed solution depending on the mix ratio you use. If you do have dark surfaces to treat and you are worried about a visible residue, you could swap to something like Equil Lambda 9.7. The problem with treating for scorpions is they are so difficult to kill that it requires a higher dose of chemical per gallon with most products, and a wider area you have to cover. There is not going to be an huge difference in price between many of the products as they all use roughly the same amounts. The Onslaught FastCap Spider and Scorpion Insecticide is a newer product that is supposed to give a better/faster knock down and a longer residual. It may be worth it to try this product as it will give you a few more gallons of solution than the Cy Kick and you may have to spray less often.

Bifen IT has a residual of 90 days indoors and 30 days outdoors. Repeat application should only take place if there are signs of renewed insect activity and must not exceed one application per 7 days.

Please view the product label for listed insects and more information. 

Bifen IT should not harm carpets, but it also is not labeled for broadcast application to carpets.
