The Cicadas are here!

The media blitz preceding the emergence of cicada brood X, the natural wonder (or annoyance) that gets the attention of area residents every 17 years has helped prepare most of us for six to eight weeks of their rare and dramatic presence.

Q. Are cicadas harmful ?

These messy and high profile critters are the loudest insects on the planet, but they don't bite or spread disease. Nor will they harm our children or pets.

Cicada females can injure young trees when they make slits in small branches (¼ - ½ inch in diameter) to deposit their eggs.

Q. Are there certain trees that the cicadas prefer?

The cicadas are known to prefer oak, maple, hickory, apples and nut trees.

Q. How can I prevent cicada damage to my trees?

The most helpful thing to prevent damage is to ensure young trees are as healthy as possible. Lightly prune damaged branches and be sure they are not further stressed by a lack of water as they recover. (Water and mulch all young trees regularly, of course.)

 Netting can be draped around the canopy to keep out cicadas, but do not use tight mesh such as cheesecloth, which keeps out ladybugs.

Q. Where can I get more information on cicadas?

I like trees because they seem more resigned to the way they have to live than other things do.
