HAMILTON COUNTY, TN (WRCB) -- The 13-year cicada, more commonly hatched in the Southeast, has been creating quite the disturbing buzz in Chattanooga for the past month.

And for the most part, they are just looking for a friend.

Park Ranger Allen Reynolds said, "It is mostly the males making that noise. They are looking for a mate. That is their purpose in life to reproduce."

On a sunny Memorial Day, you couldn't lay out at Harrison Bay State Park without hearing cicadas fly though the air.

Linda Patterson said, "They were extremely loud. I called my husband and said what is that? it a big bug!"

Tough their segmented bodies and red bug-eyes look intimidating, the good news: they are practically harmless.

Reynolds said, "They don't bite or sting at all."

Cicadas are hatched in massive numbers.

We're told there can be a least a million in a single acre of land.

Above ground, they generally live in trees, but mainly stay underground feasting on roots.

Cicadas are more of a danger to trees than your own personal garden

Reynolds said, "They can damage some trees or those that are diseased."

That is why you mainly catch them in heavily wooded areas, but it's not uncommon to find cicadas in your backyard.

If you don't see them, you're bound to be like Emily brooks who can't seem to go anywhere without hearing them.

Emily Brooks said, "It is really hard to put that screeching noise out of your mind. Even when I'm floating in the pool and they are in the trees. They are gross."
