It can take several months to get rid of a large infestation. Infestations do not get large quickly and, unfortunately, they do not go away quickly, either. Yes, Gentrol can be used in the very same cracks and crevices where you spray Phantom and can be sprayed behind and under the refrigerator to control German Roaches. For roach control, you should repeat applications every 4 months. These insecticides will just kill the roaches that come in contact with it, but as long as you are keeping the Vendetta Plus seperate from the Phantom Aerosol and the Gentrol IGR they will not interfere with each other.
IGR’s including Gentrol Aerosol IGR when used alone will not kill roaches or insects in general as they are only growth inhibitors and stop the growth cycle and reproduction phases. A successful roach treatment program should include a residual insecticide, insect growth regulator and roach bait and repeat applications every 10-14 days will be needed to fully eradicate the colony. The number of retreatments can vary depending on the level of infestation. If you are still seeing roach activity after 60 days, you will want to rotate roach baits as they can develop a resistance or bait aversion. .
You will not always see dead roaches with any product as they will die where ever they die but Gentrol IGR does not kill anything directly only prevents young from maturing into reproducing adults so used as part of a program.

Gentrol Aerosol is the same thing as Gentrol Point Source Stations just in an aerosol form and will work in the same way by transmitting its vapor through the air to disrupt the life cycle.

Since mealworms are an immature stage of an insect, though, we recommend you don't use Gentrol in the area the mealworms are kept.
