I am not sure where to post this, so here it is. Apparently this is the year for the big emergence of Cicadas. Now, I am only 20 and have lived in the U.S. for thirteen years, so I wasn't around for the last big emergence. Do these insects affect lawns? Do they affect plants? The last thing I would want to have happen, is several installation jobs and then have those insects come and destroy the work and put me out of money. Anyone have any information?
