We do not recommend mixing together two pyrethroids such as Bifen IT and a permethrin product. These products are too similar, and you could create a repellency issue rather than allowing insects to actually contact the treated areas. If you want to add something to Bifen IT for faster intiial knockdown, then we suggest a pyrethrin and/or PBO product such as ExciteR Insecticide.
Yes, Bifen IT can be used to treat fire ant mounds directly as well as broadcast over the lawn. Please view our How to Get Rid of Fire Ants Guide for step by step instructions and a helpful video.
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.
Bifen IT cannot be used on areas that will be used for grazing by animals. Please let us know what you will be treating so that we can offer a product that will fit your needs.
Yes, Bifen IT would work to treat flies. It dries clear and is odorless. You can apply the mixed solution to lawns, trees, shrubs, and indoors. It has a long lasting residual. You will need to retreat during the fly season once every 30 days.
Bifen IT should be mixed at the rate of 1 oz. to 1 gallon of water for ticks.
Yes, Bifen IT is toxic to fish and other aquatic life. It should not be used near water.
Bifen is not used to control moles. This product is an insecticide that will control lawn infesting pest like ants, roaches, crickets, worms, caterpillars, ticks, etc. The best way to control moles is with a product specifically labeled for them, such as Talpirid Mole Worms, or Giant Destroyer Gassers. You can review all of the available options on our Mole Control page. Please let us know if you have any questions.
Yes, Bifen IT can be used with a hose-end sprayer.
According to the Bifen IT product label, Apply 1 fl. oz. per 1,000 square feet when using broadcast treatments. For mound drenches, dilute 1 teaspoon of Bifen IT per gallon of water and use 1 to 2 gallons of finished dilution using sufficient force to penetrate the top and allow dilution to flood ant channels. Treat a four-foot diameter around each ant mound. Application should be made in late evening or early morning when it is cooler (65° - 80° when insects are most active. NOTE: A spray rig calibrated to apply 1 fluid oz. per 1,000 square feet of Bifen I/T in 5 gallons per 1,000 square feet contains the equivalent dilution (1 teaspoon per gallon) required for fire ant mound drenches in the spray tank.
Yes, Bifen IT will kill bed bugs. The mixing rate is 1 fl oz per gallon of water. Be sure to treat every 10-14 days until you do not see activity for 30 days.
Also, please take a look at our Bed Bug Guide for tips on how to treat and prevent bed bugs in the future.
Yes, Bifen IT is labeled for bees and can be used indoors and outdoors around the perimeter of your home. The mixing rate is 1 fl oz per gallon of water. Bifen IT can be reapplied every 30 days as needed. This is a residual so it will not kill them on contact. Once they come in contact with the treated area, they will die within a few days.
Bifen IT will not treat for roundworms in a yard. We do apologize but we do not carry a product for the lawn that is labeled for roundworms and we are not aware of any products available that would take care of this issue.
Generally it is necessary to take non chemical steps to treat this. Keeping dogs from a contaminated area for at least 1 year will prevent infestation and if that is not possible then removing and replacing the soil in area. Removing feces from the area as well when dropped is needed as well.
Bifen IT is not labeled for slugs or snails so we would not recommend it. Instead you can use a product like Monterey Sluggo Plus Snail & Slug Killer
Bifen alone will not eradicate fleas. You will also need to mix in an IGR to break down the reproductive cycle. Bifen kills the adults that come in contact with it, but then you still have the immature fleas growing and then reproducing. It is a constant battle without the IGR. We recommend Nyguard. Treatment should be reapplied after 14 days if needed and may take 2-3 or more applications. Humidity will not effect the Bifen, it can last up to 30 days on outside surfaces.
Bifen IT is labeled for ants in general.
For crazy ants, we generally recommend our Raspberry/ Cariibean Crazy Ant Kit. It comes with everything you will need to do a complete treatment for crazy ants.
It is recommended the maximum use rate of InVict Blitz Ant Granules be applied on the initial application. InVict Blitz Ant Granules, a bait specifically designed to be palatable to Rasberry/Caribbean Crazy ants. InVict Blitz will be identified as a food by worker ants and carried back to the colony to be fed to the larvae. InVict Blitz contains imidacloprid and when fed to the ant colony will cause high mortality through ingestion and transfer to other ants. It is important to bait early in the season (February - March) to reduce colony sizes. InVict Blitz can be re-applied on a weekly basis. Apply a two foot band around the perimeter of a building which would equate to 4 oz of material / 200 linear feet. All turf and landscaping areas of the property can treated with 4-8 oz per 1000 sq ft., or 10-20 lbs. per acre. The high rate is recommended for the best results. Full applications of Invict Blitz can be reapplied in one week. Applications should also be made around exterior electrical boxes where these ants are known to invade.
It is important to incorporate an application of the liquid non-repellent insecticide Taurus SC. The treatment area is one foot up the structure and one foot away from the structure.
More than two applications of Taurus SC per calendar year can be made only if applied according to one of the following frequency and dilution rate application scenarios. DO NOT exceed the specified number of applications per calendar year.
The use directions include up to four (4) applications per year at the 0.03% dilution rate for outside surfaces and along the foundation perimeter of listed structures.
0.03% 4 times/calendar year OR
0.06% 2 times/calendar year OR
0.03% 2 times/calendar year and 0.06% 1 time/calendar year
Treatments may be made as a low-pressure general surface spray (coarse flat fan), crack and crevice spray or wall void application, where ants enter the structure, trail around the structure, or where they crawl and hide. For exterior perimeter treatments, apply the rate that's listed above of Taurus SC finished dilution to surfaces up to, but not to exceed, 3 ft. up and 10 ft. of sod out from the foundation. Mounds or nests can be treated directly.
Treatments are to be made up to 10 feet around areas where ants are found associated with utility wires (electrical, telephone or cable). Foam treatments can be applied to structural voids where ants may enter, trail or nest.
Up to four treatments are permitted per year per structure, but the second application may be made within 60 days.
Indoors:
Ants will go inside a structure looking for food, water and shelter. CimeXa Insecticide Dust is a desiccant, non-repellent, no odor insecticide dust that will remain active for 10 years, if it remains undisturbed. Apply CimeXa Insecticide dust at a rate of 2 oz per 1000 sq ft in areas where these ants are likely to be present such as behind baseboards, wall voids behind cabinets, sinks and tubs, cracks & crevices, crawl spaces, around electrical conduits and other areas. When the ant comes in contact with CimeXa they will die.
Bifen IT is not labeled for treating parasitic insects. We do not currently carry any insecticides that would do so.
Bifen IT can be toxic to aquatic life, so it should not be used indoors in or near aquariums or reptile habitats. Bifen IT is safe to use outdoors as directed on the product label and indoors as a crack and crevice treatment. For other pets such as dogs and cats, it is safe if animals are kept out of the treatment area until the application is dry. If you are having trouble with ants indoors, then our Indoor Ant Kit is a great choice. This kit contains two different baits which get carried throughout ant colonies, refillable bait stations, plus Temprid Ready Spray to be used along doorways, window frames, and other places where ants are likely to enter the structure. You should always cover aquariums before using insecticide sprays indoors. Our most popular choice for treating ants outdoors is Taurus SC used around the perimeter of the home. Please see our Ant Treatment Guide for more tips and product recommendations.
If you are using Bifen IT to treat an active flea infestation, you will need to re-treat 14 days after your initial application. It is strongly recommended to also use an insect growth regulator (IGR) such as Archer IGR in addition to the Bifen IT in order to stop the fleas from reproducing. Please take a moment to read over our Flea Control Guide for more information on how to implement a successful eradication program.
