Insect Growth Regulators
Growth inhibitors or insect growth regulators (any of which is commonly
known as an IGR) are products or materials that interrupt or inhibit the life
cycle of a pest. Many people loosely use the terms "birth control for
roaches" or "birth control for fleas." If an animal cannot
reach adulthood, it is not capable of reproducing. By inhibiting the
maturity of an insect, we keep it from reaching the critical adult stage, thus
stopping the life cycle and infestation. In layman's terminology, an IGR is not an insecticide (in the bug killing
definition) but is a man-made protein that only effects certain insects or
groups of insects.
When used indoors, Methoprene (the active ingredient in Precor,
Precor 2000, Extinguish
Fire Ant Bait and others) will prevent the egg and larvae stages of fleas
from developing, with a 3 to 7 month residual. Use alone for prevention or
tank mix with an approved insecticide for existing problems. Precor also
works on Cigarette Beetles.
Methoprene (or Precor) is not photos table and is for indoor use only, unless
used in controlling mosquito larvae.
The IGR Nylar is the active ingredient in Archer, Flea Fix, IG Regulator and NyGuard IGR Concentrate. This material is photo stable (can be used outdoors and indoors) and inhibits the growth of fleas and roaches. Nylar has a 3 to 6 month residual indoors and can last 30 days when used outdoors. This IGR can be used alone (for roach and flea prevention) or tank mixed with an approved adulticide. Available in liquid concentrate.
This IGR is the active ingredient used in Gentrol, Gentrol Point Source, Gentrol Aerosol. Hydroprene is not photos table and is for indoor use, only. Use this IGR when eliminating, controlling or preventing cockroaches (roaches) and many pantry pests. Cigarette Beetles are not affected by Hydroprene; use Methoprene instead. Can be tank mixed with adulticides (insecticides) or used alone. Available in liquid concentrate, aerosol and in solid dispensers.
