The Mosquito Program at Columbus Public Health aims to reduce the risk of diseases that mosquitoes can spread to humans. We do this by measuring, monitoring and controlling mosquito populations through several tactics, including tracking, treating standing water, and conducting sprayings. Because of the comprehensive and strategic nature of our program, sprayings are based on surveillance and the presence of disease, and conducted when conditions are favorable and mosquitoes are most active. We do not conduct mosquito sprayings by request. To learn more about which areas we plan to treat based on CPH surveillance, view our mosquito treatment map.

Protect Yourself From Mosquitoes


Columbus Public Health (CPH) tracks mosquitoes to monitor the size of mosquito populations and to check for the presence of disease. Below are links to tracking results for this season.  View Mosquito Tracking Results

Standing Water Treatment

Aside from removing standing water, larval mosquito control is the most effective method of controlling mosquitoes.  As part of our larval mosquito control efforts, CPH investigates mosquito complaints and treats standing water to kill mosquitoes before they become adult mosquitoes capable of spreading disease. CPH uses products that are not toxic to humans or other animals and insects in areas such as floodwater sites, swamps, ditches, catch basins, abandoned swimming pools, tire piles and retention ponds.  

Residents may report mosquito breeding areas at 614-645-3111 or 311 online.

Mosquito Control

CPH treats to kill adult mosquitoes in areas with high mosquito counts and disease presence in area parks, bike paths and neighborhoods between dawn and dusk, using low toxicity chemicals. Spraying usually begins the first week of July, however it may be earlier depending on mosquito activity. View Areas to be Treated
