Activating Gentrol Point Source is as simple as squeezing the raised end of the plastic, adhesive-back device, releasing the Gentrol IGR onto a filter paper. Gentrol Point source should not be used to eliminate a roach population by itself but be used in conjunction with roach baits and cockroach killer gel etc.
Hydroprene (active ingredient) is a bio rational insect growth regulator similar to insect growth hormones that occur naturally in roaches and stored product pests – that disrupts the life cycle of certain insects in the egg and larvae stages of development, essentially making it a type of birth control for insects.
Gentrol Point Source IGR do not act as an adulticide, so they should be used as part of a broader integrated pest management approach and the IGR helps to keep target insect populations under control, which is especially useful in areas where conventional sprays and foggers are not appropriate or where baits are less effective due to competing food sources. Gentrol Point Source also helps to achieve more rapid results than using adulticides alone since surviving insects are not able to re-establish the population.
