Cluster Flies

Another phone call I got was from a friend complaining about large, slow flies. These sound to me to be cluster flies. They look like house flies except they are slightly bigger and a slow flyer. Many times you can swat easily as with a regular house fly it is not as easy to get them. Cluster flies will start to head to a house in August and hang out around the cracks and crevices of door frames or window frames and will over winter in a home. Many times they emerge on warm days in the winter or come spring time. If there are alot of them I usually recommend vacuuming them up with a hose vacuum. You can spray, but that is messy and unnecessary as these flys are slow and can usually be caught or killing with mechanical means.
