Bifen IT - Questions & Answers

Bifen I/T is used in poultry housing and facilities as long as the chickens are removed from the area while you treat them. You should still be able to use it in their grazing areas with no issue since they are not actually feeding on the grass/potential seeds placed out but on the insects in that area after everything has dried. If you have any concerns with the Bifen I/T usage, another option that is safe to use in grazing areas is Essentria All Purpose. You still have to remove the chickens during the application but once dry is safe to return just like the Bifen IT. Neither product should have any effect on their eggs at all as long as you are following usage instructions. 

It is recommended that once you mix Bifen IT with water you should use it up within 24 hours.

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.

Bifenthrin products used to be considered a good form of termite treatment, but bifenthrin acts as a repellent and now a days almost all professional termite companies are using non-repellents, such as Termidor SC or Dominion 2L.  Termidor will last 10+ years in the soill and Dominion will last 5-7 years.  We have a great article called How To Do A Termite Treatment that explains how to perform a treatment using a non-repellent termiticide.

We would recommend our Complete Ant Kit because it fills the dietary needs of most species of household ants providing effective ant control indoors and out and Bifen IT as a general insecticide spray that is tough on ants and spiders. Be sure to keep bait and spray completely separate to prevent contaminating the bait. Place the bait stations along ant trails and close to ant activity and spray along baseboards window frames, door frames, corners of the rooms, and around the perimeter of your home spraying 2 feet up the side and spraying 2 feet out on the ground all the way around your home.
