Larvicide Program (2023)
A spring application of the larvicide is planned to be conducted by helicopter to stagnant water within 2 km of the Town of Parkhill, Village of Ailsa Craig, and the Hamlet of Nairn to control the larval stages of mosquitoes. The Spring Aerial mosquito program is timed to control the snow-melt mosquitoes and the early summer larva.
This biological larvicide contains the active ingredient “BTI” and is very specific to mosquito larva (information regarding the product can be found below). The application is weather-dependent and will take place between April 3, 2023 and June 30, 2023.
Larvacide Application Process
The Spring Aerial mosquito program is timed to control the snow-melt mosquitoes and the early summer larva. The program can provide control typically into May with the aerial application. The rest of the season is dependent on precipitation, and once into June, the tree cover starts to interfere with the effectiveness of the application by air.
If any standing water flooding is found in May/June time frame, please report it to Kevin Taylor (@email or 1-866-648-7773) at Pestalto Environmental Health Services Inc. Unfortunately, after the larva has emerged into adult mosquitoes, there aren't any biological controls that will work.
When early summer arrives, the Middlesex-London Health Unit (MLHU) monitors and controls vector mosquito species to reduce the spread of West Nile Virus (WNV) and other vector-borne diseases such as Eastern Equine Encephalitis (EEE). The MLHU performs surveillance and sampling at about 250 standing water sites located on public property throughout Middlesex-London. Visit their website to learn more about MLHU's Mosquito Surveillance, Control and Standing Water.
