NyGuard's active ingredient is Pyriproxyfen, an Insect Growth Regulator (IGR), which is a juvenile hormone mimic (JHM). This insect control system prevents pest developments. The naturally occurring juvenile hormone regulates and stimulates the developmental process of insects. High concentrations of juvenile hormone stimulate the molting process. The level of juvenile hormone then drops to low levels, which leads to normal maturation of the larvae (larva to pupa, pupa to adult, or nymph to adult molt).

NyGuard insect control system interferes with this synchronized balance of hormones during the molting process. Treatment with NyGuard IGR introduces and maintains high concentrations of juvenile hormone mimic at critical points during the insect developmental process. Thus, normal maturation of larvae or nymphs is prevented. The result is the insect stays in an immature stage indefinitely. When this happens the insects with complete metamorphosis will continue to molt from larva to larva until it dies. Insects with incomplete metamorphosis will remain in nymph stage, or have morphological deformation, maturing into sterile, non-reproductive adults. This insect control system will keep your infestation problem from getting out of control.

NyGuard IGR disrupts the normal metamorphosis process of immature insects. Treatment with NyGuard will disrupt the growth, development and reproduction in many insect species in a manner that is environmentally acceptable. The biological results in the target insects are most commonly death or deformity with sterility.

NyGuard IGR does not kill adult insects. For best results, use NyGuard in combination with an insecticide that will kill existing populations of insects. Once the active insect populations have been eliminated, NyGuard insect control system will remain to disrupt the maturation of eggs or other immature stages of the insect population.

NyGuard insect growth regulator controls 29 types of insects, including ants, cockroaches, crickets, fleas, flies, moths and stored product pests.

Effective both indoors and outdoors, NyGuard IGR can also be used in food areas with no set back. The formula lasts up to seven months and can be applied via carpet shampoo, diluted spray or ULV/fogger.

NyGuard insect control system causes morphological abnormalities in eggs, larvae or nymphs, preventing them from maturing into reproductive adults. It can also be used in conjunction with a non-IGR insecticide when adults are present to act as a residual to disrupt immature that have yet to emerge.
