Precor IGR Concentrate - Box (10 x 1 oz. bottles)

Only Precor IGR's molecules move to the places pre-adult fleas live, like the base of carpet fibers and between furniture cushions - in short, the sources of a flea infestation. Precor IGR targets fleas in the egg and larval stages of development. As a result, pre-adult fleas cannot produce new infestations of breeding, biting adults. PREVENTS ADULT FLEA EMERGENCE FOR 7 MONTHS.

For control of active flea infestations, this product works best when combined with an adulticide such as Suspend SC or Demize E.C. which will help to provide quick knockdown of adult fleas.

See our entire selection of professional IGRs.




Precor® IGR acts on the immature stages of a flea’s 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 an approved insecticide labeled for adult fleas. Effective, long-lasting indoor control of pre-adult fleas - up to seven full months. Mix with water to make 1 gallon of finished product. 1 oz.

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

When applied to surfaces where fleas are found, such as carpets, upholstered furniture, and pet sleeping areas, PRECOR prevents adult flea emergence for up to 7 months. Controlling fleas on pets is important to prevent introduction of adult fleas indoors. If fleas are a problem on pets, treat the pets with an effective EPA registered flea control product.

METHOD AND RATE OF APPLICATION
Prepare a diluted spray solution with a final (S)- Methoprene concentration of approximately 0.007%, by adding 1 oz of PRECOR to 1 gallon of water. Partially fill the mixing container with 1/2 gallon of water, add PRECOR, shake well, and then add the remaining 1/2 gallon of water. Shake well before each use. When tank-mixing, follow the directions above except add the product to tank mix first, agitate, and then add PRECOR, agitate and complete filling of spray tank, and agitate once more. Apply at a rate of 1 gallon of the diluted spray solution per 1500 sq ft of surface area with any low pressure sprayer with a fan tip that is typically used for indoor applications. Treat all areas harboring fleas, including carpets, furniture, pet sleeping and bedding areas, and throw rugs. Treat under cushions of upholstered furniture. Avoid contact with treated surfaces until dry.

When applying to upholstery where staining could be a concern, apply dilution to a small inconspicuous location to determine if possible staining could occur. Generally, PRECOR will not stain areas that would not be stained by water alone.

    5 of 5 stars  Precor cure!
    By Zac in Western PA on 08/15/2010

    I bought this stuff as backup. I used a bunch of the Precor foggers along with some Ultracide to get rid of the flea issues I was having. They took care of the problem. I bought this stuff just in case I needed it. Precor does the job, folks! Fleas have been bad in my state this year. EVERYONE has had fleas. EVERYONE! I gave 2 bottles away for people to try. They used this as the IGR (like box states) and then used cheap store brand foggers to kill the adults. They also agree, this stuff works good for the non-adult stages.

    5 of 5 stars  Flea Control
    By Dagmar in Blountville, TN on 08/01/2011

    I ordered this after I found an empty bottle left by a pest control company that I had been paying every month, but cancelled because I was not happy with their service. I looked Precor IGR up on the internet and was very pleased to know that I could order it myself and do the pest control. I already knew it worked and was happy that I could save money by doing it myself. I liked the free shipping and the customer service rep. was very helpful. I am glad I asked about the existing adult fleas as this product does not deal with that issue. She directed to another product to mix with Precor IGR and I am happy to say, both products work wonderfully. After my initial investment, I will be saving money and be free of fleas and ticks.

    5 of 5 stars  Precor IGR Concentrate
    By Jc in Onalaska, Texas on 07/24/2011

    Had used Precor IGR Concentrate some years ago but it became unavailable at any of the outlets in this area. Precor is probably the absolute most effective product for the control of fleas. The area here is having a sand flea epidemic/infestation due to migration of sand fleas because of the severe drought conditions. It took three applications of Demize EC and Precor IGR to finally render the house flea free. The first application was a mixture of four ounces of Demize and two ounces of Precor in two gallons of water. The second and third application were done with two ounces of Demize and one ounce of Precor in one gallon of water. This was done on three successive Friday mornings. The fleas gradually disappeared, and haven't seen any fleas since.

    5 of 5 stars  Precor combined with Suspend SC
    By T in Spencer, WV on 11/06/2011

    I used this product in combination with Suspend SC for a flea problem that many other products failed to eradicate. One application and no fleas or signs of fleas for over two weeks. One word of caution, there was a stout chemical odor for about an hour, but we just closed up the house and left for the afternoon and aired out upon return. Product worked fine for our family and we were all impressed that it actually performed as advertised.

QIs Precor IGR safe around dogs and cats?
I know you said Precor IGR is safe after it is dry. I have only hardwood floors in my house. Will it harm my dog who lays on them, even when it is dry?

ANo, once the Precor IGR is dry there is no worries about harm to a pet that lays on the surface.  Remember that Precor IGR is not an insecticide; it does not kill the insect.  It is a product that prevents adult insects from reproducing and is more of a pheremone type chemical that "messes" up the life cycle process of an insect.  It is very safe around children and pets and this is why it so popular to use these products in schools, day cares, and dog kennels.

QHow long does is take Precor IGR Concentrate to dry after application?
I need to treat 2 bedrooms, living room, and kitchen. I don't have anyplace in the house to stay while waiting for the product to dry, so I've got to find someplace to go. The length of time it will take to dry will affect my choice of place to go.

ATypically most liquid applications take about 30 mintues to dry.  Specific times will vary based on temperature in the home and other factors.

QIs it safe to apply Precor IGR to mattresses and box springs for flea control?

AYou do not need to actually spray the mattress and boxspring with Precor for it to effect fleas that may be hidden there. If you spray around the area where the bed is located the fleas will still be effected because of the unique molecules of this product. You should also thoroughly vacuum the bed to remove as many fleas eggs and larva as possible.

QI got Precor IGR on my skin. Is Precor IGR safe?
I read that methoprene (Precor IGR) is not toxic to humans. And it is found in some foods. I got this all over my body even in my hair and did not wash it off. What is the worse thing that could happen to me? Will I go bald and my skin sag?

AMethorprene (Precor IGR) is a very safe product that is non toxic to humans.  I'm sure you have showered off by now.  There should be no issues or worries with the product, it just needs to be washed off.

QHow much Precor IGR Concentrate do I need for the whole house?
We have had local pest control spray down the whole house TWICE, bathed pets, we cleaned all clothes and have laid down diatomaceous earth. Our main problem was in the basement where they did a crevice treatment, but it has since moved to both first and second floors. We have fleas EVERYWHERE. Beds, clothes, hair, pets, AGAIN. This is getting very out of hand! Moving onto 3 months now with flea problem. Really need the help! We have no carpet in home.

A

One container of Precor IGR concentrate will treat 1500 square feet. The amount of product used will depend on how much area you are treating. This product is only a growth regulator so it will take time to eliminate fleas. We generally recommend that you use an insecticide as well in combination with the growth regulator. Be sure to treat every 10-14 days with an insecticide until you no longer see activity. 

Please check out our Flea Guide for tips on how to treat and prevent fleas.

QHow can I control fleas inside my home with Precor IGR?
I have used precor an conquer 3 times in last three weeks. After I spray fleas are gone for a day or two then they are back any ideas. This is inside a house, no pets inside.i see small an big fleas

A

If you have sprayed 3 times in the last 3 weeks, you might be spraying too much product and you are spraying too soon. Conquer Liquid Insecticide and Precor IGR are both great options. Flea treatment control requires the infested areas to be vacuumed before the application, spray and vacuum everyday after the application. If a second or third treatment is needed, they need to be done 14 days apart and no sooner than that. Please refer to our flea treatment guide for more information.

QWhat happens to the Precor IGR if it freezes in the truck on the way?
The temperature is in the 20's.

A

If Precor IGR freezes, as long it was only frozen for a very short period of time, and it goes back into a solution (the way it usually looks), it should be fine to use. If it appears that there are particles floating at the top, the product appears discolored, or the product will not go back into a solution, the product should be discarded and replaced.

QWhen using Precor IGR, can I place cats in another room in the house until it's thoroughly dry?
Basically what I'm asking is can I do one room (closed) at a time but keep cats in another room SAFELY. of course, I wouldn't let them reenter a sprayed room for at least 4 hours and I would open windows in sprayed room to help it dry.

A

Yes, removing the cats from the area treated with Precor IGR is a good practice. They can go into an area that has not been treated until the treated area dries completely. This generally takes 1-2 hours depending on how heavily you spray.
