Is an Gentrol IGR necessary if i do not have a roach infestation? I spray twice a month with Tempo Ultra SC both

Inside and outside my house. I have exhausted my supply of Gentrol but don't feel I need it anymore since I don't have an infestation.

Answer:

Gentrol IGR Concentrate would be best used when you have an active infestation.  For roaches it can last 4 months.  Tempo SC Ultra should only be applied once a month outside and once every 90 days inside.
