Do I need to reapply when it will rain? When can I walk on my lawn? When can I mow?
Prime Source Imidacloprid 2F T/I needs to be watered in after application in order for it to get down to the roots and be absorbed. It will not be able to do this until it is so absorption will just have to wait until it rains. It is safe to return to the treated area once the application is dry. Mowing should be delayed at least 24 hours
