Help please! is gentrol good for controling a bed bug infestation?

Nothing is "good" : For this. Gentrol aerosol is an insect growth regulator that disrupts the development of different insects to include bedbugs. It is not a repellent. It may be helpful but in general a great deal of additional effort is required to get rid of bed bugs. Declutter entire bedroom & any other effected rooms.
