Field Notes
The mosquito’s reputation as the world’s most dangerous animal is mathematically accurate and frequently underappreciated in temperate climates where the diseases they carry feel remote. In North America, West Nile Virus is a real and present concern, and the itching, sleepless outdoor evenings are reason enough to act. What most homeowners don’t realize is that the mosquitoes biting you in your yard almost certainly bred in your yard — in a clogged gutter, a forgotten bucket, or the saucer under a flowerpot. Effective control starts with eliminating those breeding sites and then treating the resting habitat: the shrubs, tall grass, and dense plantings where adults shelter during the heat of the day.
