Demize Nylar IGR is a product that is meant to treat fleas and roaches indoors. Although you could use it outdoors, it is not recommended because it is not formulated to remain effective when it is in sunlight. It breaks down very quickly. We do carry another IGR product that is formulated for outdoors and is photo-stable called Archer IGR. It works the same way as the Demize Nylar IGR, which is to prevent adult fleas and roaches from reproducing. These products are effective in slowing down populations, but you should mix these products with a insecticide for faster knockdown of adult insects such as Conquer or Onslaught. You can mix the Archer IGR and one of the other insecticide products I mentioned in a one gallon hand pump sprayer and apply it over your yard and landscape. All of the products mentioned can also be used indoors as well.
Demize Nylar IGR will not work to keep centipedes out of your home. This product is an insect growth regulator that helps disrupt the breeding cycle of fleas and certain cockroaches only. Demize Nylar IGR is not an insecticide or an insect repellant. Demand CS would be a good choice to use around the outside of your home to eliminate centipedes. You should apply the product to door frames, window frames, places where utilities enter into the structure, around the bottom of the foundation and out onto the ground directly around the foundation. You can also limit favorable conditions that the centipedes need to thrive..
