Cicadas are on the march in parts of Pennsylvania and if you've ever heard them, you know they make a racket.
It's especially bad in Robeson Township in Berks County where the shrieking "hum" for the last two weeks has been constant.
The sound is from a new emergence of cicadas that, after 17 years underground, are out looking for love.
The bulging, red-eyed, black and orange insects are everywhere. They are in the trees, the grass and all along people's driveways and walkways.
One woman said she has them on her porch, her grill, in her clothes and all over the house.
Cicadas crawl out of the ground every 13 or 17 years to fly around a few days, mate, lay their eggs and die.
That racket they produce is actually the male's mating call, which goes on like a never-ending car alarm.
