Mosquito Surveillance Site Submission

Mosquito Control

MCHD works closely with the Indiana State Department of Health staff on mosquito surveillance and trapping of adult mosquitoes in Monroe County. The Monroe County Health Department responds to all mosquito complaints. When standing water that breeds mosquitoes cannot be eliminated, it can be treated with larvicides to prevent the emergence of mosquitoes and the spread of vector borne illnesses. 

Monroe County Code Chapter 362
The vector control code states that a person who owns, leases, occupies, possesses or has charge of any land, place, building, structure, stacks, or quantities of wood, hay, corn, wheat, or other grains or materials, or vessel or water craft: "shall not permit the above to become infested with pests or vectors having adverse health significance to humans, domestic animals, or livestock."

Culex Mosquitoes

Culex is a genus of mosquito, of which several species carry and transmit mosquito-borne viruses of significant concern to human health. Culex's role as the primary transmitter of West Nile Virus is its most notable feature. The Culex mosquito prefers shallow, shaded, standing water in which to breed and lay its eggs. Potential breeding sites for these mosquitoes often include: wooded areas (especially those with shaded areas, standing water), small ponds, bird feeds, clogged roof gutters, old tires, recycling containers & garbage cans, and even your pet's water bowl. Some mosquito species are known to breed in spaces as small as a bottle cap!

West Nile Virus
The risk level for human West Nile Virus (WNV) infection in Indiana is about average compared to the rest of the United States. According to the Indiana State Department of Health, there was 175 WNV infections in mosquitos and 4 WNV disease cases in humans in 2019. Monroe County had no lab-confirmed positive results for West Nile Virus in mosquitos, humans, birds, or horses in 2019. 

How Can I Help? 
The MCHD is always looking for volunteers and suggestions for trapping sites across the county to increase the activity of our trapping and testing program. Areas with frequent mosquito activity during dawn and dusk and wooded areas with sufficient standing water are conducive for Culex mosquito activity. Public or private lands are acceptable.
