JUNE 21, 2019 UPDATE:

It has been a very prolonged, wet spring and most areas of Southern Ontario are experiencing large numbers of adult mosquitoes.  Precipitation in May made it difficult to time a second aerial application, resulting in a hatch, which is what we are currently experiencing. If you live in close proximity to a wooded area in any parts of Southern Ontario, you should expect greater presence of mosquitos than in the past several years due to this precipitation. The current program is a larvicide program, and unfortunately, there are no really good choices for controlling adult mosquitoes after they have hatched.  Ideally, we will soon experience some hot, dry weather to help burn off the adult population that we are experiencing now.   Surveillance has been conducted, and in 95% of the areas that were sampled, no mosquito larva was found.  At this time, it would not be feasible to conduct a ground or secon aerial application. We will continue to monitor the situaton throughout the season.
