Precor IGR has been around for a long time. I believe we started to use and sell it in 1985, and I would not think of doing a flea job without it.

Product Information

Precor IGR Concentrate

Precor Insect Growth Regulator (IGR) lasts up to 7 months with its active ingredient, Methoprene 1.2%. Precor IGR prevents the flea from maturing into adult stages.

Precor IGR is usually used combined with a residual insecticide (to kill the adult fleas), but may be used alone if you can spray it before a flea infestation occurs. Due the life cycle of a flea, Precor IGR takes from 4-6 weeks to entirely work.

How to Apply Precor IGR

  • Mix 1 oz of Precor to one gallon water to cover 1,000 - 1,500 square feet. It works best on rugs and carpets. If you have hard floor surfaces, we suggest Precor 2000 Aerosol or Ultracide Aerosol.
  • Spray Precor in areas where fleas are found, particularly where the pets stay. You can spray carpets, upholstered furniture, pet beds, and pet sleeping areas with Precor IGR. Make sure to spray this IGR in all areas where you think your pet has traveled. Wait for surfaces to dry before pets reenter the sprayed rooms. Precor IGR is sensitive to strong sunlight and may only last 4-6 months in those areas.

Target Pest

Fleas : Precor IGR Concentrate acts on the immature stages of the life cycle. Flea eggs deposited on or flea larvae crawling onto treated surfaces will not develop into adult fleas. Existing adult fleas and flea pupae are not affected, and thus, Precor IGR Concentrate is generally used in conjunction with approved insecticides labeled for adult fleas, such as Conquer or D-Fense SC.

To prevent infestations before they start, apply Precor IGR prior to flea season.
