Also, can I spray directly into a drain with DF 5000 drain gel?
Gentrol Aerosol and 565 Plus XLO are two completely different products that are not comparable. Gentrol Aerosol is an insect growth regulator that helps break the breeding cycle of listed insects, but it does not kill them. 565 Plus XLO is a pyrethrin product that offers a fast kill of listed insects but no residual control. These products are usually used together to help control an infestation of drain flies. You would use the DF5000 in the drain to help remove the organic matter that the drain flies breed and develop in. The Gentrol Aerosol should also be applied to the drain. The 565 Plus XLO should be used to help knockdown the active flying adults around the infested room.
