Be On The Lookout For Crane Flies

Now is the time when we begin to see nuisance crane flies enter into buildings. Sometimes these flies are called “mosquito hawks” but unlike mosquitoes, these adult flies do not feed. These flies are large in size with long legs and they are only alive long enough to mate and lay more eggs for the next generation. Even though crane flies are not medically important, they are a nuisance when they enter homes and other buildings in large numbers.
The larvae of crane flies are gray in color and cylindrical in shape. These larvae are usually found in layers of decomposing leaves or in compost piles from December to January. The larvae of the crane fly have chewing mouthparts and feed on organic matter. They are beneficial, since they are decomposers.
Usually no control is needed since the adults are only here for a couple of weeks out of the year. Just remember to keep doors and windows closed as much as possible to prevent them from entering buildings!
