Bifen can also be used to create a pest barrier by spraying the solution around your home to keep them at bay. This helps keep mosquitoes and other pesky creatures from entering your home.

How to Use Bifen Indoor

Undoubtedly, most insecticides are DIY products and will only work well on the intended pests if applied appropriately. Bifen is not exceptional and needs a proper application to eliminate pests in your home. Here is a step-by-step guide that will help you apply the product effectively:

  1. Read the product’s label: It is a requirement by law that all manufacturers print a product label and display it at the back of the container holding the product. This provides vital information on the ingredients, safety precautions, and application instructions. Therefore, ensure you read the label to get this vital information.
  2. Wear protective clothes: You need to protect yourself from Bifen since it is a chemical like any other and can harm your body. You may need gloves, a mask, and a long-sleeved shirt or long pants.
  3. Prepare your solution: Bifen is always produced in a concentrated form and must be mixed with water to perform the function. To prepare the solution, fill a clean spray tank with a half gallon of water and add 1 oz of Bifen. Next, fill the other remaining half-gallon of water into the sprayer and shake well. You shake for a minute or two.
  4. Apply the mixture: After shaking well and ensuring the product is properly mixed with water, you need to apply it where the pests congregate. In this case, you can begin spraying the bedroom, where most mosquitoes congregate. Ensure you spray the baseboard, cracks, and crevices because mosquitoes like hiding in such places. Start from the top to allow the product to flow freely on the walls to cover the entire area.
  5. Let the solution dry: This is a step most people ignore. Always ensure you give the solution time to dry before allowing other people and pets to enter the room. This way, you will be sure no one inhales the chemical. One hour is always enough for the product to dry up.
  6. Repeat When Necessary: Though the product can protect your home for up to three months from the day of the initial spray, you may need to reapply, depending on the severity of the pest, until you achieve optimal control. You can do this after a week or two.
