Bifen IT - Questions & Answers

We would recommend applying a product like Bifen IT in our Chapin Slide Pump Sprayer. This sprayer will reach well over 30ft. We do not carry any products that can be applied in a pressure washer for this type of insect control. You will mix the product at 1 oz per gallon of water per 1,000 sq ft monthly on the exterior. Please let us know if you need anything else.

You could use phantom in that area and around the perimeter of your home 2-3 feet up and out. Phantom works well to eradicate carpenter ant colonies, because the active is transferred by the worker ants into the colony.

You should be sure to apply Bifen IT where it would make the most contact with the pest you are trying to treat for so if scales on the bottom of leaves, treatment should be directed there.

We only recommend applying Bifen IT as labeled, which would be once every 30-60days. Over application could cause the insects to become irritated and rapidly reproduce. Bifen IT will kill with in a matter of minutes.

You should not spray Bifen IT into standing water. You should use BTI Mosquito Briquette Dunks to treat standing water. BTI Mosquito Briquettes are a sustained-release larvicide that conveniently floats right on the water surface. These briquettes can be used in virtually any standing water site where mosquito larvae grow. As the briquettes float, BTI (or bacillus thuringiensis israelensis, a natural mosquito-killing biocontrol agent) is slowly released at the water’s surface and gradually settles in the water where it is consumed by mosquito larvae. Bti kills mosquito larvae before they are able to grow into mature, biting adults, eventually controlling the mosquito population. Additionally, the toxin will continue to be released into the water for a period of 30 days or more, providing continuous kill. Each briquette will effectively treat up to 100 square feet of surface water regardless of depth. Bifen can be used to help control adult mosquitoes on your property. Be sure to spray the undersides of leaves on trees as bushes as this is where mosquitoes like to hang out during the heat of the day.

You can use between .5 and 1 ounce per gallon of water. Depending on how your hose end sprayer is set up, you would need to select one of those two rates on the dial to properly dilute it. Either rate is acceptable for the treatment of springtails.

We are not aware of any issues with using a bifenthrin product on St Augustine.  This active is known for being super gentle on plants, so it should not harm it when used as directed on the product label.

You can definitely mix Bifen IT in smaller quantities to fit your needs as long as you are following the general guidelines described on the product label. Be sure to thoroughly saturate the carpenter ant gallery for best results.

The Material Safety Data Sheet for registered pesticides generally includes avian toxicology reporting. The MSDS for Bifen IT contains Effects on Birds information in sections 12 on page 4.

Bifen IT will kill termites that come in contact with the chemical. To eradicate termites you want to use a product that has a transfer effect. Termidor SC is a great product to use to treat termites. Please see our Termite Control Page. Scroll to the bottom of the page and find information on identification and treatment for termites.

Yes, Bifen IT and Archer can be mixed together to treat for ants and other listed pests. 

Bifen IT will not kill trees only listed insects. If you have any severely damaged or dead trees, they should be removed to help prevent the beetles from infesting healthy trees in the surrounding area.

The label does not authorize to apply Bifen IT to any type of carpeting. You will want to focus treat the cracks and crevices of the room along baseboards, corners, door and window frames with a hand pump sprayer for a residual control. We advise to vacuuming consistently and sanitizing the treated area will help eliminate the fleas quicker. We also suggest using an IGR (insect growth regulator) such as Archer IGR to prevent the future infestation from developing for a better control.

Bifen IT is NOT labeled to be used around any type of edibles. Anything that came in contact with the drip line should not be consumed.

Bifen IT has a residual of up to 2 months indoors and out. As long as the product was dried, before the rain, it should not have washed away. 

While you could tank mix the two, the Mosquito Barrier is going to work against the effectiveness of the Bifen I/T for probably at least the first week or two. You are spraying Bifen on surfaces moquitoes would land on and harbor in so that when they touch the treated surface they pick it up on their bodies and die from it. If you are spraying Mosquito Barrier you are using it to repel the mosquitoes away from areas you dont want them or are trying to keep them from harboring. So essentially by mixing the two together, you are repelling the mosquitoes away from the Bifen I/T so it would not affect them. Outside of an initial contact kill the mosquito barrier isn't going to provide killing action for you long term, only repellency. Bifen is actually the better product to use on a consistent basis in main target areas on the property where mosquitoes would be found, and use the Mosquito Barrier around patios and other "hangout" areas to keep them at bay until they have died from landing on the Bifen-treated surfaces.
