Temperature: Warmer weather accelerates mosquito life cycles.
Rainfall: More rain increases standing water pools.
Vegetation: Dense foliage provides shelter.

Understanding these helps locals and visitors anticipate peak mosquito seasons. Learn more about environmental impacts at Environment Canada.
