What are MMCD helicopters doing?
Helicopters apply a dry granule or pellet containing a natural soil bacterium or a mosquito growth regulator to wetlands and large areas of standing water to prevent larval mosquitoes from becoming biting adults. These are bio-rational control materials which specifically target mosquito larvae and pose no risk to human or animal health. MMCD helicopters DO NOT apply liquid control materials that target adult mosquitoes. Learn more about our mosquito control program.
If you have any questions or concerns about MMCD helicopter activity, please call us at (651) 645-9149 or use our Submit a Tip form.
