I'd actually like to show a little mercy and use a biological to kill them so as not to kill beneficial insects, but that can take 2 days for them to stop eating and die. In this heat, the trees will be defoliated in that time.Get'em Tim! No mercy!
With what I just sprayed, they were mostly dead by the time I rinsed out the sprayer and came back inside. If we don't have too much rain in the next couple days I'll get 5-7 days of residual before I have to spray again.
