One area of my yard is a nesting ground for at least 25 nests this year.The brood chart does not show 2016 as a peak 13 or 17 cycle year.Any one else got large numbers? Just heard my first cicada this morning.
No cicadas here, but every year I release praying mantises egg sacks into my yard to cut down the bugs. A mantis will kill everything including cicadas.

13 and 17 year cicadas ( usually the all-black ones with red eyes) are not out every year, but there are a number of annual and shorter-period (3, 5, 7, years) that can be found each summer. Cicada killers have no way of knowing when big brood emergences will be. Usually if there are a lot of them it's because hunting was good last year. Males can't sting, but good luck telling them from females. The only people I ever heard were stung by them either stepped on them or purposely antagonized them. They are usually even-tempered - unlike yellow jackets.
On the open ground, they leave a pretty distinctive large, ant hill like, mound around their burrows. Not uncommon to find dead cicada hulls left at the entrance.
Just saw some yesterday and have multiple burrows/nests in my yard. I've only had this house a year and a few months and I definitely don't remember seeing any last year.
Search online. They are easy to find in the spring. You buy egg cases which contain 50-200 eggs (most of which die before maturity). They are indiscriminate eaters, eating pretty much any insect: good, bad, or each other.
