Mistakenly, according to Doug Gaydon of Mississippi State University, many people associate the warm temperature with mosquito numbers.
Water means everything.
The Cooperative Extension entomologist said another misconception involves the effect of cold weather on the two-winged insects. If nothing else, mosquitoes are quite adaptable. They simply find protected places such as home attics, hollow trees or brush piles when the temperature drops below 62 degrees Fahrenheit. But if it's warm enough, you could still be bitten by a mosquito in late December. Since mosquitoes are so dependent on standing water, keeping them under control can be as simple as doing yard work.
