Bifen IT

How Bifen IT Works

Bifen IT is a liquid concentrate insecticide that contains bifenthrin, a synthetic pyrethroid. Pyrethroids work by disrupting an insect's nervous system causing a weakened state followed by death. Bifen IT does not provide an instant knockdown of pests, rather, pests pick up the residual active ingredient by contact. Bifen IT is a repellent insecticide since it acts quickly enough that social insects such as ants cannot create a pheromone trail. This means that Bifen IT will be most effective as a barrier for target pests with a thorough application.

Target Insects

Bifen IT is very effective on Japanese Beetles, clover mites, ants, termites, fleas, ticks, spiders, scorpions, roaches, millipedes, earwigs, army worms, mealybugs, mites, grasshoppers, pillbugs, cutworms, sod webworms, weevils, leaf miners, box elder bugs, bees, wasps, sowbugs, crickets, and turf and ornamental pests. Bifen IT even has an expanded label to include control of stink bugs indoors and outdoors.

Target Uses

Talstar One, Bifen I/T and other Bifenthrin generics control over 75 common insect pests, including termites. Bifen can be used as an indoor and outdoor pest control, turf and ornamental application, and for treating pests in food-handling areas. Both Talstar One and Bifen I/T contain microcrystals that do not break down easily with rain once they bond to surfaces. Both Talstar One and Bifen IT are clear substances that leave no stains on painted surfaces. Bifen IT can last up to 6 months outside. See below for list of approved usage sites.

ACTIVE INGREDIENT: Bifenthrin - 7.9% synthetic pyrethroid

Application Instructions

Best applied with a 1 gallon sprayer. Apply to outside foundation and all entry points such as around windows, doors, etc. Always read the label completely before use.

Yield

• 1 bottle (4 oz.) concentrate yields 4-8 gallons of finished solution.
• 1 pint (16 oz.) concentrate yields 16-32 gallons of finished solution.
• 1 quart (32 oz.) concentrate yields 32-96 gallons of finished solution.
• ¾ gallon (96 oz.) concentrate yields 96-192 gallons of finished solution.
• 1 gallon (128 oz.) concentrate yields 128-384 gallons of finished solution.

Standard Application Dilution rates / Mixing Ratios

• 0.33 oz./gallon of water – 0.02% - prevention, low level infestions
• 0.5 oz./gallon of water – 0.031% – general indoor or outdoor use
• 1.0 oz./gallon of water - 0.06% - severe infestations, less frequent treatments, longer residual, quicker knockdown
• 1 gallon of finished solution should cover 1,000 square feet when using a hand pump sprayer

* See the video above for general use mixing and application instruction using a Chapin Premier 1 gallon sprayer.

Use in the Following Areas:

In and around such areas as homes, commercial and industrial buildings, recreational areas, athletic fields, lawns and ornamentals; livestock and poultry houses; gardens, parks, lawns, grounds and other ornamental sites; flowers, foliage pants, non-bearing fruit and nut trees, shrubs, ornamental trees; interior and exterior plantscapes such as those in hotels, office buildings, shopping malls, etc.; both food/feed and nonfood areas of food/feed handling establishments; aircraft (excluding cabins), apartments, bakeries, bottling facilities, breweries, buses, cafeterias, candy plants, canneries, dairy product processing plants, food manufacturing plants, food processing plants, food service establishments, granaries, grain mills, hospitals, hotels, industrial buildings, laboratories, meat/poultry/egg processing plants, mobile/motor homes, nursing homes, offices, railcars, restaurants, schools, ships, trailers, trucks, vessels, warehouses, wineries

Indoors

Use 0.33 to 1 fluid oz. per gallon of water for residual pest control in buildings and structures and on modes of transport. Apply either as a crack and crevice, pinstream, spot, coarse, low pressure spray (25 psi or less) or with a paint brush.

Apply as 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.

• Do not use as a space spray.
• Pay particular attention to cracks and crevices.
• Limit repeat application to no more than once per seven days and only if there are signs of renewed insect activity.

* Bifen IT may be converted to a foam for residual treatment of voids or as a spot spray when visual marking of application is desired.

* Bifen IT is NOT labeled for control of bedbugs in residential or commercial areas except for in livestock and poultry housing structures.

Outdoors

General application for crawling pests - Mix 0.5 to 1 oz. of Bifen IT in one gallon of water and apply to the outside foundation of the home, approx. 3 feet up the side of the house and 2 feet out from the house. Also spray entry points into the home such as around windows, pipes, doorways, etc. For general preventative treatment, apply Bifen IT once every 3 months.

Mosquitoes: To control mosquitoes around buildings, landscapes, and lawns, dilute 0.33 to 1.0 fl. oz. per gallon of water and use one gallon of dilution per 1000 square feet as a general spray. Bifen IT can be mixed at lower concentrations and applied at higher volumes to ensure application of the proper amount of product to a given area.

Bagworms: Use 0.125 to 0.25 oz. per 1,000 square feet (or 5.4 - 10.8 oz. per 100 gal.). Apply as a full coverage foliar spray. Use of a Chapin Slide Pump Sprayer will help reach higher into trees. For optimum control treat when larvae have started to hatch and are young, directing spray to contact as many larvae as possible.

Chinch Bugs: Use 0.25 to 0.5 oz. per 1,000 square feet. In order to optimize the penetration of the insecticide to location of the chinch bugs, irrigation of the grass prior to treatment may be necessary.  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 fl. oz. per 1,000 square feet) to control populations made up of both adults and nymphs in mid-summer.

Lawn applications: A hose end sprayer, such as the Chapin hose end sprayer, may be used to apply Bifen IT for lawn pests. Use up to 1.0 oz. per 1,000 square feet. Higher volume applications may be more effective with some pests, so you may want to calibrate the sprayer to a lower rate (for example, 0.25 oz/gal.) and use more water to cover a 1,000 square foot area.

Termite Applications: Bifen IT may be used for pre-construction or post-construction prevention of subterranean termites. Use 1.0 oz/gal. of water (0.06% solution) for most termite applications. For preconstruction horizontal barriers (such as under a concrete slab), use 1 gallon of solution per 10 square feet. For perimeter barrier treatments, use 4 gallons of solution per 10 linear feet. See our article How to Do a Termite Treatment, for further instructions on perimeter termite treatments. See product label for full instructions on using Bifen IT to control subterranean termites.

Extra Tips

• Allow at least 30 minutes after application before allowing pets or children into treatment area. For best results, allow 24 hours after outdoor application before expected rainfall or watering. Some outdoor applications may require irrigation before or after application. (See product label)
• Use with an IGR such as NyGuard IGR for control of all life stages of insects such as fleas.
• Store out of direct sunlight and extreme temperatures.
• Concentrate should be viable for 3-5 years. If separation occurs, shake well before using.
• Do not apply more than 1 oz. Bifen IT per 1,000 square feet.
• To avoid or delay pest resistance, especially on ornamentals and trees, it is recommended to use an alternate class of pesticide in any application program.
• Not labeled for use on commercially grown plants or edible plants.

    Outstanding results on spiders, mosquitos, ants, fleas/ticks
  By Charles in West, TX on 06/18/2010

  I own a campground in Texas, and I have been using Bifen IT for several years. I mix 1 ounce of Bifen IT per gallon of water and spray a fine mist on the lower branches of the trees in the campground (up to 6 feet off the ground). The mist that does not land on the tree branches falls to the ground, so I don't have to spray the ground. I treat the campground once every 6 months, and I have absolutely no problems with any insect. It kills mosquitos and ants almost immediately upon contact, and it takes about 30 seconds to kill spiders. When spiders are sprayed, they usually remain still for 15 seconds. Then they begin to feel the effects of the insecticide and their legs start moving frantically back and forth. At the end of 30 seconds the spider is dead. I'm not talking about little spiders. The spiders we have around here have bodies the size of a golf ball. By the way, I should mention that I add 1/4 cup of Dawn liquid dishwashing soap to 15 gallons of mixed insecticide. The liquid soap helps the insecticide stick to the foliage. Excellent product!

    It's amazing!
  By Nick on 10/09/2008

  I bought Bifen IT because I saw it so highly recommended on this website. I had seen at least one cockroach each day since moving into our new house, so I knew that it needed spraying. The instructions for the Bifen IT product were clear and easy to understand. I also got a 2-gallon sprayer to use, and it worked really well. I sprayed around the foundation up to 3 feet and about 2 feet away from the house, along with any other cracks and crevices around doors, etc. I haven't seen any cockroaches in the 6 weeks since I sprayed. It's amazing! I did find a dead one outside the house around the perimeter of the porch. This stuff really works. For the price, it's a bargain, and you can save yourself a lot of money by taking the hour or so to completely do your house. I plan on re-spraying every 3 months to keep the bugs out. If you're looking for a good deal on pest control, do it yourself with Bifen IT. I also had some questions about how to use it and the customer support people here on the site were very prompt and helpful.

    "Secret" solution
  By Sharon on 02/21/2008
  Verified Purchase

  I live in South Florida and about 4 years ago I noticed a 'new' variety of ant which came in fast and furious. The first year wasn't terribly bad but the second year they had multiplied 5x in numbers. I saw a pest control truck at a neighbors house and asked the guy what he knew about this new ant. He called it the "Caribbean Crazy Ant" (I looked it up on the Internet and sure enough, that was the 'new' ant). He told me that he could control this ant with a "secret" solution, and by the third year I called him for help. I live on a 1.3 acre landscaped lot with many trees, bushes, plants. He sprayed my yard and all the foliage for $200. I guess he thought that I would not attempt to spray this huge yard myself so he actually divulged his "secret" solution. He told me he used Talstar. So back to the Internet I went and found the generic Bifen IT brand. I ordered it and sprayed my own yard the next year for less than $30. The ants stayed away from my house and I will use this product each and every spring from this point on! BTW: of course, not only did it control the crazy ants, it has kept all other pests away as well!

    Great stuff
  By Butch in South Jersey on 06/22/2009

  I like this better than Malathion and Sevin. I spray our lawn, perennials, annuals, shrubs, trees, rain gutters, under our deck and foundation with Bifen IT. I'm on a wooded acre and spray as much of my property as I can. I give everything a good wet spray with a hose end sprayer which offers more coverage than a tank sprayer. I spray a few days after a rain when everything is dried out. I've always thought that the rain and moisture breeds mosquitoes so that is a good time to spray them. There is no odor. But it's the insect protection that is fantastic. We spend a lot of time outside in the yard and gardens. We also spend a lot of time on our back deck at night. In the past it would be unbearable. This stuff kills bugs dead and keeps killing which seems like weeks at a time. Pesky mosquitoes and gnats are history. If you wanna be able to spend time outside and those flying insects are a problem then this is the stuff you need. I just hope the state doesn't outlaw it.

    Extremely effective
  By Scott on 06/15/2008

  I use Bifen IT to control fleas outside where my cat hangs out (front porch and adjacent yard area). It has proven to be extremely effective when applied every 3 to 4 months during the spring and summer. I highly recommend this product.

  Great product. This product is water base and works well spraying inside the house without a harsh smell. It kills almost everything, especially those brown spiders that seems to come around during the summertime.

•   Good product
  By Wes in New Orleans La on 03/31/2018

  We recently had mosquito Joe and Mosquito Authority quote us $60/month to treat our yard for mosquitos. So I did some YouTube watching and learned about this product, this is the same product the professionals use. It took some reading and watching to figure out how to mix and apply, but it was easy. I mix 1 fluid ounce with 1 gallon of water in a pesticide pump container. We live in the city on 1/2 -1/3 acre. I use about 1.5 gallons to spray the back front and sides of the house every 25-30 days. I have also conciencies my neighbors to start using this product which gives us an even larger barrier around our house from Mosquitos. We still see mosquitos, but the volume is down ?. With a pregnant wife, it’s important to keep mosquitoes away. Domyown.com gave me the knowledge and convidence to use poison on my own at a fraction of the cost the professionals would charge. $40 will last me 2 years.

•   Out Off Control Big Head Ant Infestation
  By Everardo in Margate Fl. on 03/20/2018

  Before Bifen IT, I was on the verge of having to hire a professional. We had already spent over a hundred dollars on sprays and granules, which were harmless to kids or animals. Then I tried making my own baits after identifying the type of ant. After several weeks of this method (which at first appeared to be functional), suddenly we had an infestation both in the front and back yards. After doing more research and preparing to contact a professional exterminator, I found Bifen It. This pest control not only took care of the infestation, but it is pet and children friendly (when used as directed). On top of everything, it is very economical. No other product I found in stores worked like this one. I definitely will be purchasing this in the future.
