I have somtimes wondered if the lack of mosquitoes was related to the abundance of bats that race through the gardens each evening.
* I believe the thing that controls overall Mosquito abundance is
topographic relief, which tends to suppress standing water. Topography
is absent in eastern Ontario, but abundant in Nova Scotia. In the
Catskill Mountains of New York, topography is so omnipresent that the
houses don't even have screens on their windows.
