No products found.

Bifen IT (or Bifen I/T, either one is correct) is a great product with many positive customer reviews from DIY homeowners and pest control professionals alike. This excellent product can be used on a wide variety of pests in many different areas.

For normal insects and pests, the EPA has approved it to be sprayed inside or outside in the home, garage, barns, poultry houses, livestock facilities, hospitals, nursing homes, businesses, schools, municipal buildings, and hotels.

Inside, it works in crack and crevices treatments to kill cockroaches in kitchens, ants around doors, windows, baseboards, around plumbing and electrical intrusions, under appliances. It’s great stuff with a long-lasting residual impact for up to 90 days.

Outside, Bifen IT insecticide can be used in a fogger for mosquito control or sprayed on athletic fields to prevent an infestation of fire ants or other biting insects that might attack players during their games. Once it dries, the players are safe.

For termites, you can use Bifen under pier-and-beam houses or around the foundations of slab houses in a trench-and-treat application.

It’s a repellent termiticide designed to be used in barrier treatment applications on homes, businesses, and more.

It can be used in a foamer, which creates a foam similar to shaving cream. The foam is then injected into the wall voids between the 2x4’s.

The foam expands until it fills the void. Any termite that ventures into those voids comes into contact with it and dies.

Whether you’re killing ants or termites, getting rid of spiders or earwigs, Bifen IT will get the job done with professional results and a long-lasting residual protection.

What Is Bifen IT?

Bifen is manufactured by a company called Control Solutions Inc., to be used as both a termiticide and a broad-spectrum insecticide. DIY homeowners can mix it and use it themselves for ordinary pest control, inside and out.

If you’re treating for termites, you’ll need to check with the authorities in your state to determine if you can use it yourself or if a professional pest control exterminator is required. The law is different from state to state so be sure to check before you spray.

It’s a liquid concentrate, meaning it has to be mixed with water before it can be sprayed. The active ingredient in it is concentrated to 7.9% by volume of the liquid. Depending on the insect you’re targeting you’ll need to dilute it as shown below.

  • 1/2 ounce of the concentrate per gallon of water to achieve a 0.03% solution.
  • 1 ounce of the concentrate per gallon of water to achieve a 0.06% solution.
  • 2 ounces of the concentrate per gallon of water to achieve a 0.12% solution.

Except in special cases, use a 0.06% solution for most of your insect-control spraying. The 0.03% solution should be used primarily around poultry while the strongest 0.12% solution should be reserved for yard spraying or termites.

The 16-ounce bottle has a built-in “tilt-and-pour” spout that doubles as a measuring device for the concentrate. The product label, which folds out like an accordion, has charts so you can determine what rate to use for which pest in what location.

It is labeled for aphids, bed bugs, carpenter ants, centipedes, chinch bugs, cockroaches, earwigs, fire ants, gnats, grasshoppers, millipedes, mole crickets, mosquitoes, pillbugs, scorpions, silverfish, spiders, spider mites, springtails, stink bugs, termites, and more.

Spraying it inside requires the purchase of a one-gallon pump sprayer. You’ll also need some disposable gloves. Blue jeans, a long sleeve shirt, and a wide-brim hat are recommended as PPE (Personal Protective Equipment).

Spray it along all the baseboards, around the cracks and crevices on all the windows and doors, under and behind all the major appliances, up in the corners where spiders like to make their webs, and behind all the furniture. You should use 1/4-1/2 gallons inside.

If you’re spraying it outside, a backpack sprayer is recommended. Most of them hold 3-4 gallons, making it perfect for creating a three-foot-wide barrier around the entire house right at the foundation. You should also spray about two feet up on the side of the house.

Spray up under all the eaves, around the windows and doors, around all the plumbing intrusions, around the A/C unit, and any wiring intrusions. Insects use those to gain entrance to your house.

Pay special attention to weep holes if your house is brick masonry or stone. Insects can use them like a superhighway.

What’s The Active Ingredient In Bifen IT?

There are 16 different major classes of insecticides. Bifenthrin, the active ingredient in Bifen IT, is in the Synthetic Pyrethroids class.

Synthetic Pyrethroids are a variant of a natural extract from chrysanthemum flowers. That botanical extract, called pyrethrum, kills insects quite well but it breaks down quickly in sunlight, rendering it useless after only a few days.

did you know bifen it review fact

Synthetic Pyrethroids were the solution to the problem. They are highly toxic to insects but are very safe around humans, particularly in their diluted spray form. The first pyrethroid was developed in 1967 and there have been dozens of variants since.

Does Bifen IT Work?

Yes, it does. It attacks the central nervous system in insects. Exposure comes when they eat it or touch it. Simply crawling across a wide band of it will expose them to a lethal dose. The small body size and low body temperature of insects makes them vulnerable.

Bifen is a repellent pesticide, meaning it tends to repel insects that come near it. The tendency isn’t a hundred percent so any insects that continue across it will be killed.

Is Bifen IT Harmful To Humans or Children?

The Environmental Protection Agency (EPA) has determined that all pyrethroids share a common mechanism for their mode of action. In October of 2011the EPA used that assessment to determine the relative risk from exposure to pyrethroids.

Even using the most conservative assumptions in their model(s), the EPA determined that pyrethroids such as bifenthrin, the active ingredient in Bifen, does not pose a significant risk to children or adults when used as directed.

However, the active ingredient bifenthrin has been linked to reactions in people suffering from asthma or allergies. The link isn’t clear and no direct causation has been identified, so the jury is still out on this one.

The EPA notwithstanding, there is an exception to every rule, and pest control operators (PCO) have learned from sad experience that it’s better to be safe than sorry – and sued.

Occasionally someone will eat a large quantity of bifenthrin, whether by accident or in a suicide attempt. They experience sore throats, nausea, abdominal pain, and vomiting, using within a very short time after eating it, sometimes almost immediately.

Furthermore, most PCOs recommend not spraying around anyone who is younger than two years old. The internal organs of infants and small children are still developing and tiny amounts of foreign chemicals can have a profound impact on their development.

Because of this possibility, it’s important to minimize children’s exposure to pesticides. Keep them out of the area while it is being treated and then for at least an hour afterward to give it a chance to dry.

On one last note, all pesticides are not created equal. There is a variant of Bifen IT called Bifen XTS that has an active ingredient concentration of 25.1%, over three times stronger than Bifen IT. PPE is definitely required when you’re using it.

It is mainly used for termite work or to knock down heavy flea, mosquito, or cockroach infestations. Because of its strength, be extremely cautious around it.

Is Bifen IT Safe For Cats and Dogs?

This question is a bit more complicated than the same question concerning people. The only truthful answer is, it depends on what concentration they’re exposed to.

Read Also: What are the top pet safe roach killers?

Yes, Bifen is probably safe for cats and dogs if it has been properly diluted and mixed according to the directions on the product label. The concentration of the active ingredient bifenthrin, from 0.03% to 0.12%, is so low it probably won’t harm them.

No, Bifen isn’t safe for cats and dogs if they gain access to the concentrate and start drinking it.

They could experience vomiting or diarrhea, lethargy, ear twitching, paw flickering, and excessive drooling. Loss of coordination has also been reported.

If your pet chews up the plastic bottle the Bifen comes in and you suspect they’ve been exposed to the concentrate, take them to a veterinarian along with a copy of the label on the bottle.

Bifen IT Vs Other Products?

Bifen IT vs Suspend SC

No products found.

No products found.

Suspend is related to Bifen because both of them are pyrethroids, but the active ingredient in Suspend is Deltamethrin. It attacks insects the same way bifenthrin does but is poorly absorbed through the skin.

The normal spray concentration for Suspend is lower than Bifen, 0.03% as opposed to 0.06%. It works poorly on wasps and bees, despite what the label says, has virtually no odor, and is not labeled for use against termites.

It is less toxic to people, children, and pets than Bifen. It can be used outside but we recommend it mainly for inside use.

Bifen IT vs Phantom

No products found.

No products found.

Phantom started life exclusively as a termiticide then the label was gradually expanded to include other insects. It uses Chlorfenapyr as the active ingredient. It’s a member of the class of insecticides known as pyrroles.

It has to be ingested in order to work. It disrupts the mitochondrial action that creates energy for the cell, preventing the creation of ATP. The cell dies from a lack of energy to carry out its functions. This process spreads to other cells and kills the insect.

Phantom has an advantage over Bifen because it is a non-repellent. Insects can’t detect it and aren’t repelled. It is, however, much more expensive than Bifen and requires 3 ounces of concentrate per gallon of water, so you use it up faster.

Bifen IT vs Dominion 2L

No products found.

No products found.

Dominion 2L uses Imidacloprid as the active ingredient. Imidacloprid is in the class of pesticides known as neonicotinoids that mimic the action of nicotine.

Imidacloprid is primarily used to control sucking insects, termites, and some soil insects. It is also used to control fleas on pets when it is put on flea collars and flea drops. It has been in use in the United States since 1994.

A 27.5-ounce bottle makes 50 gallons of solution. That and its low cost make it useful for spraying large yards.  It is cheaper than Bifen but doesn’t attack nearly as many insects so there is a bit of a trade-off.
