Bifen IT - Questions & Answers

Bifen IT and Suspend SC are similar in the insects they target and areas where applied. Bifen IT uses the active ingredient bifenthrin and Suspend SC uses deltamethrin. Both actives will treat the most common insects such as Ants, Spiders, Pantry Insects, Silverfish, Fleas, Roaches, Mosquitoes, Stink Bugs, Scorpions, Ticks, Fleas, Pillbugs, Chinch Bugs, Earwigs, Millipedes, etc. 

No, Bifen I/T is not labeled to be used in a fogger. You can use it in a handheld or backpack sprayer or a mist blower such as the Solo 451 or an Stihl engine powered device.

Yes, Bifen IT is labeled for spiders. The mixing ratio is 1 fl oz per gallon of water. Be sure to spray the areas where spiders are present so that they will come in contact with the treated area, such as around windows, doors, etc. This can be done every 30 days as needed indoors and outdoors. 

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.

No, Bifen IT cannot be used in a ULV or thermal fogger, however it can be applied in a hand held or backpack sprayer or a mist blower such as the Tomahawk Power Mist Blower.




 

Per the product label, Bifen IT  should be applied a coarse, low pressure, crack and crevice or spot spray to areas where pests hide, such as baseboards, corners, storage areas, closets, around water pipes, doors and windows, attics and eaves, behind and under refrigerators, cabinets, sinks, furnaces, stoves, the underside of shelves, drawers and similar areas.

Bifen IT can be mixed with an insect growth regulator such as Nyguard IGR to break the flea cycle.  Nyguard IGR will prevent the young from maturing into reproducing adults, thereby keeping the colony from getting larger while the Bifen works to eliminate.  Bifen should be applied every 2 weeks outside for flea treatment and Nyguard once a month.

Bifen IT can be sprayed onto and into the shakes to provide some relief from the silverfish. Be sure to use the highest usage rate of 1 oz of Bifen IT per gallon of water for the fastest knockdown and the longest lasting residual. You will need to reapply once a month to keep up the barrier.

Bifen IT would be a good choice for tick control. We would recommend the liquid formulation for tick control because you can spray it on tall grasses and bushes where ticks are known to harbor (it is recommended that you spray the entire areas where ticks are known to harbor including the grass). Once Bifen IT is dry it is safe for the dogs to return to the treated area. Once dried, Bifen IT will not reconstitute so there is no need to worry about rain making it unsafe. The very small amount of diluted product a dog might eat if they ate some of the treated grass would be so minimal that it would simply pass through their system without causing any issues.

Bifen IT insecticide is comparable to the very popular Talstar, but is much less expensive. Bifen IT provides excellent control of over 75 insect pests, leaves a long-lasting residual for up to 3 months indoors and one moth outdoors, is odorless, non-staining, dries clear and is safe around children and pets when used as directed.  Bifen IT and the other bifenthrin products can be used both indoors and outdoors, on lawns and ornamentals, and even in the kitchen. Be sure to keep pets out of the treated area until it has a chance to fully dry. Once completely dry, Bifen IT is completely safe for your pets.
