None in Central Naperville either. I was thinking that I might not see many around the neighborhood considering almost everybody around here has used some sort of insecticide on their lawns in the past 16 years.
I was reading about them and I guess they spend their larval stage at depths of 1-8.5 feet underground, which might protect them from insecticides, but not when they are trying to emerge from the ground. Anyone have any idea how long grub killer stays active and how deep into the soil it penetrates?
It just occurred to me, that my house was about 3 years old the last time the cicadas were about, so the moderately large trees in the neighborhood would have been very small twigs then.
