Cuyahoga County Board of Health - Mosquito Activity & Prevention Update - July 18, 2013

The rainy weather we have experienced over the past several weeks created ideal conditions for mosquito breeding. As the eggs continue to hatch, we will see a significant increase in mosquito activity.

We have been responding to a higher volume of mosquito-related complaints and wish to pass along these tips to help you avoid being bitten by mosquitos.

  • Use insect repellent containing DEET, Picardin or Lemon Eucalyptus Oil. Be sure to follow label instructions.
  • Wear long-sleeved shirts, long pants, and shoes and socks. The less of your skin that is exposed, the better protected you are.
  • Keep children indoors during times of heavy mosquito activity: one hour before and after sunset.
  • Eliminate all areas of standing water by disposing of containers that collect water such as buckets, tires, flower pots and cans.
  • Clean gutters so that water drains and does not collect.
  • Clean, drain and cover pools or hot tubs when not in use.
  • Empty and refill bird baths at least once a week.
  • Fill tree holes with tar or cement.
  • Be sure that your door and window screens are tight.


No human cases have been reported to date for our county or the state of Ohio. Historically, we see more infected mosquitos in late July with infection rates peaking in August.

Symptoms include headaches, high fever, loss of appetite, muscle aches and vomiting.

If symptoms persist 2-10 days after being bitten by a mosquito, seek medical attention. Advise your doctor of your exposure to biting mosquitos.


To report areas of constant standing water or heavy populations of mosquitos, please call us at 216-201-2000.
