What We Do
The District is committed to using science based Integrated Pest Management (IPM) practices to monitor vector populations and disease presence through surveillance, targeted product applications and source reduction through inspection and vector education for our residents through community outreach. These components create the foundation of the District’s comprehensive vector control program.

Attention: Surveillance traps have recorded the first batch of mosquitoes to test positive for West Nile virus in the Decatur area. At this time, the risk is low, but residents should be cautious and wear insect repellent when outdoors during peak mosquito hours from dusk to dawn.June 25, 2025
First WNV-Positive Mosquito Batch in Macon County
The Macon County Health Department (MCHD) has received confirmation of the first mosquito batch testing positive for West Nile Virus. This batch was collected by the Macon Mosquito Abatement District (MMAD) from a gravid mosquito trap. At the time of this release, there is not a positive human case in Macon County.
The MMAD has tested 180 samples with 2 positive results. The risk of infection is currently low. However, residents should check their property and drain/dump any standing water. It is important to continue to check your property to help reduce breeding sources as this will decrease the mosquito population long-term.
Mosquitoes are attracted to standing water, bare skin, and dark clothing. It is recommended to follow the four D’s to help keep mosquitoes away:
Drain: Empty standing water every 5-7 days including watering dishes, bird baths, kiddie pools, etc.
Dress: Wear long sleeves, long pants, and light-colored, loose-fitting clothing.
Defend: Properly apply an EPA-registered repellent such as DEET, picaridin, IR 3535, oil of lemon-eucalyptus, para-menthane-diol or 2-undecanone. Oil of lemon eucalyptus and para-menthane-diol are not approved for use in children under the age of three. Insect repellents are not recommended for children younger than 2 months of age. Consult your physician before using repellents on young children or infants.
Dusk/Dawn: Avoid peak mosquito activity at dusk and dawn, when possible.
The MMAD performs daily inspections within the district and continues to treat areas of standing water that contain mosquito larvae/pupae. The MMAD staff are also looking for neglected pools, ornamental ponds, open containers and other areas that might be overlooked for mosquito breeding. If you are aware of an area that has standing water for three (3) or more days, please call the MMAD at (217) 875-2722. If you are not in the MMAD district, they can refer you to the appropriate agency.
The MCHD also conducts surveillance of West Nile Virus in dead birds. Bird collections must be fully intact without decomposition or bugs. If you find a dead bird, please call the Health Department at (217) 423-6988 ext. 1134 to report it.
Attention: we are treating catch basins this week. Please use caution as our trucks make frequent stops along the roadways to complete this work. As with any vehicle with caution lights or hazards, please move over and allow them space to work.
*Catch basins will hold water long after a rain event and when leaf litter and grass from mowed lawns accumulates, they become perfect mosquito breeding habitats.

Educating the public about the life-cycle of mosquitoes and the role they play as potential vectors is a critical component of how we protect our residents. Often times, mosquito breeding sites are cryptic and difficult to spot, even by seasoned professionals. When equipped with the right information, residents become great assets in helping to manage mosquito populations within their own communities by eliminating breeding sites and educating their neighbors.
Homeowner Tips
Mosquito control can often be a community effort. Residents are encouraged to look after their own property and remove standing water, especially after a rain event. The best way to eliminate mosquitoes is to get rid of their breeding habitats.
