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.

    I had a severe flea infestation in my garage from a stray cat. We tried flea bombs, sprays everything I could buy and have done. We closed up the garage for couple weeks cause didn't know what else to do. I did some research found this and mixed with suspend sc and the next day wow only had some tiny fleas jumping on me before I was covered in them. Within no time we were back in the garage!! We will never use anything else!

    Puppy has SEVERE FLEA SALIVA ALLERGY: After disappointing results with consistent applications of a 'big box store' product I did my homework and ordered the Precor IGR Concentrate. Coupled with Suspend SC to kill adult fleas and carefully FOLLOWING INSTRUCTIONS the environmental flea issue (as well as all other undesireables!) was quickly resolved.
    Will continue to use as directed and repurchase.
    Excellent customer service from DIY.
