How long does the PT Ultracide residual activity last ?


The IGR in the Ultracide is supposed to last for 7 months, however the adulticide you need to respray every 14 days as this is the rough hatching cycle for any that haven't already come out from your daily vacuuming. This provides an extra knockdown of any remaining adults and newly hatched fleas.
