Brood X Cicadas

Millions of Brood X cicadas are expected to emerge from the ground this month for the first time in 17 years in New Jersey and 14 other states. Brood X is the largest brood of cicadas in the U. S.

What can you expect?

  • It will be LOUD! Cicadas are the loudest insect in the U. S. The sound can reach as high as 100 decibels that is as loud as a lawn mower, jackhammer or garbage truck.
  • You may need an umbrella. Cicadas have been known to fly into people that cross their path. They could land in your hair or fly into your home.
  • You may find cicada shells all over your yard. Cicadas emerge from the ground in their nymph stage and shed their shells once above ground. You may find these shells on the ground around trees.
  • They will not be here very long. Cicadas only live for a few weeks to mate and lay eggs. Six to ten weeks after the adults die the nymphs will borrow underground to feed and grow for two decades.

Tips to prepare for their arrival:

  • Wear earplugs or noise cancelling headphones when outdoors, if you are sensitive to loud noises.
  • Keep doors and windows closed and make sure they are properly sealed and screened.
  • Carry an umbrella, wear a hat and keep long hair tied back when outdoors.
  • Make sure your windshield wipers are working. Make sure to clean off the cicada shells from your windshield.
  • Limit your time outdoors. Cicadas are least active when temperatures are cooler, morning and later evening.
  • Rake the discarded shells up from your lawn.
  • Protect tree saplings with a cover of netting or cheesecloth.
