Culex mosquitoes are between ¼” to ⅜” long, and can have a variety of coloring which is usually a base of grey, with blue, white, silver or green scales which are barely visible to the naked eye. There are over 100 species of mosquito in the US, but they’re all quite similar.
Mosquitoes have a very unique ability to find mammals by detecting high levels of carbon dioxide, which humans and other mammals release when we exhale. This is why you can be outside for a couple of minutes before they find you. Mosquitoes feed on the blood of mammals. Their bites are itchy and irritating at the very least, and many mosquitoes also carry diseases such as dengue fever, West Nile virus, yellow fever, and malaria. The best way to keep these pests away is to remove any sources of standing water from your property, such as tires, unused swings, or stagnant ponds. In many places it’s nearly impossible to avoid mosquito bites completely, but we can reduce our exposure by cutting down on the amount of time we spend outside during dawn and dusk, and using screens in our windows.
