Mosquito Control Program

The Township of Ramara's annual mosquito control program, also known as spring mosquito aerial larviciding, has been in place for more than 40 years. The program is conducted under an annual permit issued by the Ministry of the Environment, Conservation and Parks.

At one time, ground fogging was done by the Township; however, the current method is more environmentally friendly. Council has periodically reviewed alternative treatment options, however this program remains the most cost-effective for the benefits it provides.

The Township uses a granular biological mosquito larvicide, which specifically targets mosquito larvae. The single aerial application takes place in the spring, between April and May, before the larvae emerge as mosquitos. This treatment focuses on the spring Aedes species. With more than 50 mosquito species in Ontario, the Township of Ramara is not eradicating all mosquitoes. The larvicide is safe for humans, livestock, birds, fish, frogs, plants and other insects. It only affects mosquito larvae in the water.

The treatment areas only include wetland areas which are stipulated under a Ministry of Environment, Conservation and Parks permit to perform a water extermination. No spraying is conducted over residential areas.
