Precor IGR Concentrate, manufactured by Zoecon, is an effective insect growth regulator that disables fleas' life cycles for up to seven months to advance the flea control process.
It contains the active ingredient (S)-methoprene to prevent flea eggs and flea larvae from becoming adults, which prevents them from being able to reproduce.
Precor IGR Concentrate is the ideal product to introduce to a flea treatment program to manage heavy infestations. Since Precor IGR will not kill adult fleas, it should be used alongside an approved adulticide for total control.
Tools Needed
A handheld pump sprayer is needed to make indoor applications.
How to Use
- Step 1: Determine how much Precor IGR Concentrate to use by measuring the square footage of the treatment site. To do this, measure the length and width of the treatment area in feet, then multiply them together (length x width = square footage). The label states to use 1 oz. of Precor IGR Concentrate in a gallon of water to treat 1500 sq. ft. of surface area. So, for example, if you have a 3,000 sq. ft. area to treat, you would need to mix 2 oz. of product in 2 gallons of water.
- Step 2: When making applications with a handheld pump sprayer, fill the spray tank with half a gallon of water. Add the proper amount of product to the tank, and then fill the tank with the remaining half of water for a complete 1-gallon mixture. Shake the spray tank well to mix thoroughly.
- Step 3: Spray the solution on carpets, pet bedding, and other areas where flea activity has been seen. Allow areas to dry before entering.
Where to Use
Precor IGR is for indoor use and can be applied to all areas where fleas live, such as carpets, rugs, pet bedding, and furniture.
Do not apply to pets or animals. Precor IGR is not effective for use in outdoor areas.
When to Use
Apply Precor IGR to prevent flea eggs and larvae from becoming adult fleas, ultimately stopping the life cycle process.
Safety Information
Precor IGR is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
Special Considerations
Precor IGR is not an insecticide, however, an insecticide can be added to the mixed solution. Read the label of the insecticide to be sure it is compatible.
