If you’ve noticed flies coming inside when it’s cold, there’s a good chance you have houseflies. They are very common throughout the U.S., and are easily identified by their wind current and body temperature. They’re tiny, with oval bodies and two wings that overlap on the back. You can even spot them by their larvae – creamy white-gray rice-like creatures that are surrounded by a cloud of black spores.
While flies are generally a nuisance during warm months, winter flies can be a big problem. Some species will lay eggs in dark places in the home during the cold months. In addition, many flies will stay inside until the weather is warm enough to entice them to leave. Fortunately, there are some ways to minimize the impact of winter flies. First, you can lower the temperature in your home. Secondly, you can use sprays and other methods to kill the flies. An apple cider vinegar solution is also an effective temporary treatment.
During the coldest months, flies will go into hibernation. The reason for this is that they are attracted to warm places. As a result, the warmest part of a home is likely to be a breeding ground for flies. Furthermore, flies can be carriers of disease, as they pick up organisms while crawling through the air and deposit them on people and food. Infections that flies carry can include dysentery, cholera, leprod, and typhoid.
