The retreatment time intervals for Gentrol IGR Aerosol are based off the target insects being treated. For roaches, Gentrol IGR Aerosol leaves a residual of 4 months, for bed bugs there is a 2 week residual and for fruit flies/drain flies, the residual is 2-4 weeks. You would do follow up treatments at those intervals per the product label.
