Cicadas are nothing.
The only thing that is remotely bothersome is when you have billions of them in the trees doing their treacherous buzz song from hell.
17 years is the massive influx Nuke, but theres still quite a few that come out every year.
Easy to catch by hand, foot, mouth, car grill, etc. They struggle to just stay airborne.
The most fun thing to do is catch them, take those poppers (things in rice paper you throw agains the ground and pop), tape them to the cicada, light the "wick" end on fire and let the bastard fly away.
Good stuff!
