Bifen IT

Bifen IT insecticide is comparable to the very popular Talstar. Bifen IT contains 7.9% bifenthrin which is an insecticide and termiticide that provides excellent control of over 75 insect pests, leaves a long-lasting residual for up to 3 months, 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 food-handling areas of commercial establishments. One quart of Bifen IT insecticide yields 32-96 gallons. If you are looking for a low cost alternative to Talstar One, then look no further. Bifen I/T is tough on pests, but not on your wallet.



Product Documents


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.

INSECTS CONTROLLED: adelgids, American dog ticks, annual bluegrass weevils, ants, aphids, armyworms, bagworms, banks grass mites, bed bugs (not in residential areas), bees, beet armyworms, beetles, billbugs, biting flies, black turfgrass ataenius, black vine weevils, boxelder bugs, broad mites, brown soft scales, budworms, California red scale centipedes, carpet beetles, carpenter ants, centipedes, chiggers, chinch bugs, cicadas, citrus thrips, clothes moths, clover mites, cockroaches, crane flies, crickets, cutworms, deer ticks, diaprepes, dichondra flea beetles, earwigs, elm leaf beetles, European red mites, fall webworms, filth-breeding flies, firebrats, fleas, flea beetles, flies, fungus gnats, gnats, grasshoppers, gypsy moth caterpillars, hide beetles, hornets, imported fire ants, Japanese beetles, lace bugs, leaf feeding caterpillars, leafhoppers, leafminers, leafrollers, litter beetles, mealybugs, midges, millipedes, mites, mole crickets, mosquitoes, moths, orchid weevils, pecan leaf scorch mite, pillbugs, pine needle scales, pine shoot beetle, plant bugs, psyllids, roaches, San Jose scales, scorpions, silverfish, sod webworms, sow bugs, spiders (including black widow spiders), spider mites, spittlebugs, springtails, stink bugs, subterranean termites (genera Reticulitermes, Zootermopsis, Coptotermes and Heterotermes), tent caterpillars, thrips, ticks, tip moths, treehoppers, twig borers, wasps, weevils, whiteflies, wood-infesting beetles (including but not limited to old house borers and powder post), yellow jackets

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.

Features

  • Pet Safe when dry
  • Virtually no odor or staining
  • Easy-to-remember mixing rates
  • Convenient squeeze and pour containers (pint and quart) make measuring and mixing easy
  • Bifen IT may be tank-mixed with adjuvants and with other pesticides, including insect growth regulators.
  • Very broad labeling for pests and use areas means you can use one product for many jobs
  • Labeled for use in food or feed handling establishments
  • Long residual for fewer treatments

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.

Compare to: Talstar P (Talstar One)  *Bifen IT has the EXACT SAME label and the same amount of active ingredient as Talstar P, the more expensive brand.

    5 of 5 stars  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!

    5 of 5 stars  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.

    5 of 5 stars  "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!

    5 of 5 stars  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.

    By Scott on 06/15/2008

  • 5 of 5 stars  Bifen IT and Fire Ants
    By Larry in York on 07/25/2017

    With 2 acres of grass and a 'controlled' fire ant problem, I find 5-15 fire ant mounts each weekly cutting of grass and mark them via orange flag then later come back and spray their mounds with this wonderful product (1 oz per gallon). Forcing a quart or so into the holes of each mound eradicates then. My neighbors do not treat theirs so I get new queens landing on my land after each rain but glad this product exits.

    By Alton in Fayetteville, NC on 07/25/2017

    After doing some reading decided to give Bifen a try. Just recently purchased a home and the detached building had a flea problem. After two thorough applications no more fleas. Have also noticed that anything that comes in contact where the product was applied dies. Numerous spiders have been seen dead on the floor. Great product!

Actually found out this is the same product our service company uses that we have come quarterly. So I've stopped their service and do it myself. I have cats and dogs and it's safe as long as you follow the directions. This product goes a long way.

    By Jeremy in country, Minnesota on 07/19/2017

    Mixed 1 oz to 1 gallon of water and the results are amazing. I live on 10 acres with heavy woods. Couldn't go in my backyard without mosquito spray ever. Sprayed the yard on a Wednesday night and by Thursday morning I noticed a difference. By Friday and for the next 3 weeks I haven't been bit by 1 mosquito. They are starting to come back now, but it lasted 3 weeks and over that time we had 7 days that it rained an 1in or more. I swear by this stuff for mosquito control!

    5 of 5 stars  Incredible - Love this product
    By Bruce in Lincoln on 07/17/2017

    I very rarely write reviews but found myself amazed at how well this product works. After researching for the last 5 years trying to find something to control my spider problem on my boat dock I'm finally done. I would go down daily and knock down spider webs, have the droppings all over my pontoon boat I would have to clean, etc. Tried several products that were supposed to work and none did. I was about to spend a lot of $$ to get a mist system installed when I ran across this website and Bifen IT. In one day after treating my boat dock with this product my issues are gone. I'm now recommending it to everyone I see. Fabulous product, great service from the website - order and delivery. Customer for life!

QIs Bifen IT safe for domestic pets?
I have three dogs, and I am scared to use chemicals.

ABifen IT is safely used in thousands of homes across the country everyday. Bifen IT is safe for use around pets when used according to the label. You should always keep children and pets away from the away while you are treating, and then once the treatment is dry it is perfectly safe to allow pets to re-enter the area

QHow does Bifen IT compare to Bifen XTS and Permethrin for mosquito control?

ABifen I/T is our most popular choice for mosquito control.  The Bifen XTS is the same product, just in a higher concentration.  For mosquito control you do not need the higher concentration, it is not necessary.  Bifen I/T would also be a better solution then permethrin because permethrin breaks down quicker in sunlight and the Bifen I/T only needs to be applied every 30 days whereas permethrin would need to be applied every two weeks.  The most important thing to remember when treating for mosquitoes is that they hang out on the underside of leaves and shrubs.  You should treat all shrubs, bushes and trees around the outside patio or wherever you hang out at around the house.  You should also treat the tree line in your yard near the forest if one exists.  Remember to not only treat the main bush or shrub but also the underside of the leaves.

QWhat type of weather should I put the Bifen IT out in? Rainy, cold, hot?

AAll of our liquid insecticides including Bifen IT should be applied in dry weather, not rainy weather.  All of the liquid insecticides are made to bond to dry surfaces and will last longer when applied when it is dry and not going to rain for at least 24 hours.  The temperature does not matter as much.  It can be applied in hot or cold weather, but it must be dry and not wet to work at its highest potential.

QIs Bifenthrin good on active termite control?

ABifenthrin 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.  We have a great article called How To Do A Termite Treatment that explains how to perform a treatment using a non-repellent termiticide.

QWhy did Bifen IT mixture have no effect on a spider?
I sprayed a strong concentration of Bifen IT mixture directly on a spider and it had no effect. Is there something I can mix with the Bifen to get spiders?

A

Bifen IT†is not designed to kill on contact and even when you spray an insect directly it can take several minutes or longer to kill it. †It will help to kill the ones that contact a treated surface as well as their food source, but how long it takes to kill after application depends on age and health of the insect, how long after application they contact the treated surface and how long they spend on the treated surface. †Spiders themselves are harder to kill as they do not groom themselves and have the long legs to keep themselves off the ground and in more contact with a treated surface. †We have a great guide here for treating spiders that might also help. If you are going to be spraying spiders directly each time, you could add a product like ExciteR to Bifen to give it a faster initial knockdown only.

I have a severe infestation of chinch bugs in my 1500 sf St. Augustine lawn. I sprayed at 1 oz per gallon and then handwatered in. I am concerned that I applied too much water...how do you know that the product is not being diluted too much? Also if I sprayed 3 days ago can I water in fertilizer now without making the Bifen less effective?

A

As long as†Bifen IT†was applied as directed on the label and watered in as required for chinch bugs (at least 0.25 inch of irrigation) after application, you can go ahead and water in the fertilizer. †It will not move much farther into the soil as it is designed to bind to the soil. If more water was used that would just have pushed it down into the soil better and will be fine.

QCan you mix Bifen IT and Atrazine together in same tank to spray on grass?

A

We do not see any reason why you can't spray†Bifen IT†and†Hi-Yield Atrazine†together. For more information on application and dilution, please refer to the product labels of each product.
