What is Bifen IT?

Bifen IT is a liquid concentrate insecticide boasting bifenthrin as its active ingredient, which is a synthetic pyrethroid. The magic of pyrethroids is their unique mode of action: they wreak havoc on an insect’s nervous system, initially weakening and then leading them to their demise.

This isn’t a fly-swatter instant-kill approach but a slow and steady process where pests come into contact with the residual active ingredient and meet their fate.

Application & Efficiency

A hallmark of Bifen IT is its versatility. It’s designed to combat over 75 pests, including usual suspects like mosquitoes, spiders, cockroaches, and ticks. This broad spectrum of effectiveness makes it a valuable weapon in any homeowner’s arsenal.

Regarding application, it’s evident that the manufacturers considered the user experience. The recommended mixing ratios vary based on the severity of the infestation, allowing users to customize their approach:

  • 0.02% (0.33 oz./gallon of water) for prevention and low-level infestations
  • 0.031% (0.5 oz./gallon of water) for general indoor or outdoor use
  • 0.06% (1.0 oz./gallon of water) for severe infestations

Each gallon of this mixed solution covers approximately 1,000 square feet, which is fairly efficient, especially when using a hand pump sprayer.

Safety Concerns

For many, a primary concern is safety, especially when pets or children are involved. With Bifen IT, once the solution dries, it’s considered pet-safe. This gives peace of mind to users who can allow their pets and kids back into the treated area after about 30 minutes post-application. 

Another commendable feature is its virtually odorless nature and absence of staining, making indoor application less bothersome. However, as with any insecticide, it’s imperative to follow the instructions to the letter, ensuring optimum safety and effectiveness.

The label suggests a 24-hour window before anticipated rainfall or watering for the best outcome. And a notable mention: don’t get excited and overdose your space – up to 1 oz. of Bifen IT per 1,000 square feet is the golden rule.

Where Can You Use It?

Its applications are vast, encompassing homes, perimeters, ornamental landscaping, lawns, industrial buildings, and even areas where food is handled. Sports enthusiasts and professionals can also apply it to athletic fields. It’s not fit for fruit and vegetable gardens, so green thumbs steer clear of those patches.


The residual effect is impressive, lasting up to 3 months. This means fewer applications over time, which is not only cost-effective but also time-saving.

Final Thoughts
In the world of insecticides, Bifen IT undoubtedly stands out. Its wide range of applications, efficiency, safety, and longevity make it a top contender. For those waging war against pests, it’s certainly worth considering. Remember always to follow the label directions for optimal results and safety. Here’s to a pest-free environment!

Note: Always ensure to read the product label and instructions before application. Different conditions might require specific precautions.
