Diseases from Mosquitoes

Mosquitoes can carry a number of diseases, including West Nile virus, which is still present in the Baltimore area. West Nile virus is a disease that is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected animal. In humans, West Nile virus generally causes either no symptoms, or mild, flu-like illness, but it can also be deadly.

Reduce Mosquitoes
Help reduce the number of mosquitoes in areas outdoors where you work or play, by draining sources of standing water. In this way, you reduce the number of places mosquitoes can lay their eggs and breed -
•    At least once or twice a week, empty water from flower pots, pet food and water dishes, birdbaths, swimming pool covers, buckets, barrels, and cans.
•    Check for clogged rain gutters and clean them out.
•    Remove discarded tires, and other items that could collect water.
