When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 0.185-.055 oz of product with for each 1,000 sq ft area that needs to be treated. Please refer the Prodiamine label to be sure of how much you will use.

We are not aware of any studies that have been performed to see how the emergence of sub surface insects such as cicadas would impact a pre emergent barrier with Prodiamine 65 over time. While any disturbance in the barrier can create a weak spot, we couldn't determine how greatly or minimally the residual would be impacted. You may find a follow up application 8 weeks after your first spring treatment of the pre emergent will help reinforce the barrier and extend its life further into the growing season.
