Mosquito Control

In order to prevent mosquito-borne diseases from affecting the citizens of Leland, Public Services employees monitor mosquito activity and respond to service calls from citizens related to mosquitoes. This program is in effect May 1- Nov. 1. 

To report a mosquito issue in your area and submit a request for adulticide spray:


OR CALL 910-371-0148

Once a report is received, a staff member will investigate the report to determine if the area meets the threshold for spray (a landing count of 7 per minute). If the area meets the threshold, a truck will be routed to the area to begin spray operations. Spraying will then continue until it appears the outbreak is contained. The frequency of spraying depends on the overall number of areas that need spraying, the available manpower, and the severity of the outbreak.



Mosquito control is more than just spraying. In order to effectively control mosquitoes, a management program must employ a broad range of strategies. These include:

Public Education

When the division investigates a service call attempts are made to educate citizens on the basics of mosquito control and what actions they can take to reduce breeding areas. Our program staff is willing to visit schools, community groups, and property owner’s associations meetings to provide educational materials to groups interested in learning about mosquitoes and mosquito control in Leland. We also have a brochure to educate citizens about the Asian tiger mosquito. To schedule a workshop, please call 910-332-4652.

Biological Control

The mosquito fish (Gambusia affinis) are relocated to mosquito breeding sites to consume mosquito larvae.

Physical Control

Roadside drainage ditches on Town-owned Right-of-Ways are maintained to remove standing water, thereby reducing the area suitable for mosquito breeding.

Adult Control

Clarke Mosquito Control products are used to manage adult mosquito populations. Ground spraying generally occurs between 6:00 PM - 12:00 AM. As a precautionary measure, people and pets should go indoors when they see the mosquito sprayer coming. People with severe allergies should notify Public Works. Ground spraying is conducted on an as needed basis. This is determined by investigations conducted by division staff in response to service calls. If you have an outdoor fish pond or keep bees, contact the Public Works Department. To request a Mosquito Service Investigation please call 910-371-0148.

Larval Control

For larval control the Town of Leland uses BTI Briquets that are based on the naturally occurring bactirum Bacillus thuringiensis, var. israelensis, Bti. It is considered to be one of the most environmentally sensitive mosquito and blackfly larvicides used in mosquito control. It contains a sustained release formulation offering activity against mosquito larvae for thirty or more days. The floating quality of the briquet provides for release of the active ingredient at the water's surface where it affects surface feeding larvae. As the briquet sinks slowly through the water column it is active on bottom feeding larvae as well.

The Town’s Mosquito Control Program operates under the purview of the Environmental Protection Agency (EPA) and the NCDENR (NC Department of Environment and Natural Resources). All application of pesticides must comply with Federal Clean Water Management Act and NPDES (National Pollution Discharge Elimination System) permit requirements.
