Mosquitoes need undisturbed, standing water to lay their eggs in; after 24 to 48 hours, the eggs hatch into larvae, and four to ten days later a New Jersey bomber takes flight. So if you have a torrential downpour, count ahead seven to ten days; that'll be a good time to stay behind a screen door. Temperatures over 80 degrees also increase mosquito mojo, while readings below 50 degrees shut them down. They prefer shade to direct sun, calm conditions to strong winds. If all else fails, you can try to outrun them; their top speed is 1.5 miles per hour, half the average human's walking speed.
