The active ingredient in I.G. Regulator is Nylar, an insect growth regulator. Nylar is similar to insect growth hormones that occurs naturally in insects and acts on the immature life stages of the flea, preventing the adult flea from developing. Flea eggs deposited on treated areas will not develop into adult fleas. Flea larvae crawling onto treated surfaces will also not develop into adult fleas.

The unique properties of Nylar eliminates the flea population, when used as directed. Nylar® causes a gradual reduction and ultimate elimination of the flea population by breaking the reproductive cycle. Nylar stops the flea life cycle and inhibits the development of the immature stages of the flea 7 months preventing them from reaching the biting adult stage. Existing adult fleas and flea pupae are not affected.

If a high population of adult fleas are present, the use of an adulticide such as Conquer may be necessary for immediate relief. I.G. Regulator compliments the rapid activity of the adulticide by providing long term control of preadult fleas before they grow up to be biting adults.

    Great stuff

    By Anonymous on 07/08/2013

    I was using Martin's to stp fleas and saw it is also good for cockroaches. I had a horrible infestation. I sprayed everything with Martin's, and it eradicated all the fleas and all the cockroaches. Best long-term treatment for both I've ever used. Took about a month to take effect, as I didn't use poison with it, but has lasted more than the 7 months. I love it. Just follow the directions, quite simple really.

    Control of outside bugs in Florida

    By Ray on 09/26/2013

    This product mixed with Bifen I/G according to the labels. It really is effective for ants, roaches, fleas in Florida. It has lasted for about six months after I spray it around the outside perimeter of the house, garage and shed. I use about 1/4 cup/3 gallons of water.

    I.G.R. (insect growth regulator)

    By David on 05/14/2016

    This product is fantasic. It basicly stops the eggs from reproducing for up to 7 months. We had a flea problem last year and no matter how many times I sprayed with the other spray, they would hatch new eggs. With in a week, we had a whole new crop of fleas. one time spray with IGR it killed everything. Customer service was very prompt and I had the product with in a few days.

Why must Martins IGR be mixed/used within 24 hrs? Does it not work if it sits for a few days?

I have to keep animals out of each room until it dries and sometimes that takes a bit of time. It is much easier if would last a couple days.

The acid in water can break down the actual chemical which is why you cannot leave the product sit in water for an extended period of time. We recommend that you mix 1/2 fl oz with a 1/2 gallon of water so you don't have to mix the entire gallon up at one time.

Can I mix Martins IGR and Martins Viper when spraying indoors?

We have been told to mix Martins Viper insecticide with Martins IGR for treating fleas indoors. However in reading the directions, Martins IGR (growth inhibitor) can be sprayed indoors on carpets, furniture, pet sleeping areas and rugs, while Martins Viper adulticide is directed to be sprayed indoors on Cracks and crevices not on couches and beds .... so how can you mix these two chemicals when they are not supposed to be sprayed in the same areas?


You are correct. Martins IGR can be mixed with Viper. Specific label instructions still apply to each product. If you find that you are needing to treat areas that Viper cannot be applied, you will need to apply the products separately. You should not apply either of these products on bedding, mattresses, or the skin contact areas of couches or other furniture.

How long do i wait to vacuum after application of Martins IGR?

I ask this because many of the Pyriproxyfen (the prime ingredient) studies via Google scholar, while talking about the sterilization of male/females adults also refer to the feces being contaminated, as such when other fleas consume it they themselves are sterilized. So would it better to wait 2 - 7 days? or just vacuum every day?

We always recommend vacuuming every day during flea treatments. Not only does this suck up the dead adults and any feces left behind, but the heat and vibrations of the vacuum help stimulate the eggs to hatch and be exposed to the product you are using. The fleas are protected inside their eggs much like a chicken egg and until broken or hatched, nothing can affect whats inside. By forcing the fleas to hatch you help control the infestation faster as they are being pulled onto a surface that has a residual insecticide of your choice and the IGR waiting on them. Please let us know if you have any other questions.
