Patrick from Wilson Nc writes,
How often do you need to apply Extinguish once soil temperatures are above 60 degrees?
You only need to apply it once to to eliminate the ants that are present at the time of the application (as long as it does not rain). If more ants come into the area, you would then need to reapply the product. This product should only be used when the ants are active.
