I have the little Bottle of Nyguard IGR concentrate.
NyGuard IGR is an insect growth regulator that does not actually kill insects. It prevent the young of the insects listed on the product label such as roaches, mosquitoes, fleas, etc. It causes morphological anomalies or changes and disrupts the expected insects' state of development, leading to sterility or death. When adults are present, NyGuard is commonly used in combination with a non-IGR insecticide to kill the insects as well.
