Couple that with the extreme heat and the life cycle of many insects is all messed up this year.
the few damages i have, are on irrigated lawns. I am afraid of not getting it watered in and do apply sometimes a bit early. If i waited 2 more weeks, none of my grub control would have been watered in except irrigated lawns.
so, in that case, hmmmmmmmmm.
also though, i experienced the same as above. more than anything though, the grubs are under threshold enough, but the skunks etc are ripping the lawns up feeding on those near wooded areas and irrigated. they know where to look
