Q.how long does D-Fense SC last?
Which is right? I'm using it inside and outside a building. Your webpage says "long lasting residual that controls pests for 3 months." The label on the bottle says to reapply after 21 days. The product label from your website says don't apply earlier than 21 days.
A.You should not reapply earlier than 21 days because of the residual, however, how long the residual will last will really depend on the elements and etc. In perfect conditions, the residual may last for up to 3 months. However, it may not last that long and we usually recommend treating anywhere between once every 1-3 months. If you have any further questions or comments, please feel free to contact us again.
