The flies of autumn are upon us! As the weather get cooler, the flies want to be inside, where the temperatures are steadier, and warmer. In the evening, if there has been an opportunity to enter your home, you will find them crawling around on TV screens, and buzzing around lamps. They also seem to be drawn to body heat, and a person at rest is a perfect target. This happens especially outside as the sun starts to set. If you have exposed skin, say an arm, or a leg, they will swoop in and land, stealing your warmth, and driving you insane, as they crawl around with their flithy fly feet! You drive them away, but they just keep coming back, and every once in a while…OUCH! You just got bit by a housefly! Or did you? While world wide, the fly most encountered around humans are house flies, but you will also be buzzed by their numerous look a like cousins! We often see the blue and green bottle flies…Those are the ‘house flies’ that look to be blue or green, and because we see them in houses, we may generically call them ‘house flies’. True house flies however tend to be very dull in color, and have very light , or dirty looking yellow markings on the abdomen, and thorax. All of these flies love to come into our homes, and search for rotting food, and you will find all of them on dog poo, and dead critters…But they don’t, or more appropriately cant bite you. Their mouths just aren’t built for biting into living, healthy skin. Now I know, everybody out there either claims to have, or knows somebody that claims to have, been bitten by a house fly. They may even be 100% positive in their minds that a house fly bit them, and they most likely even have credible witnesses to prove it. In fact if you were bitten by what you would swear on your most prized possessions to be a housefly, the viscous little demon actually doing the biting was very likely a stable fly (Stomoxys calcitrans). These flies spend most of their time buzzing around sunny open areas, but when the weather is not favorable will seek out shelter in our homes, and barns. You will also find these pests tormenting your livestock, as well. The female stable fly must have a blood meal in order to lay her eggs, and she will lay those eggs in rotting hay, straw, and grass clippings. Large hay feeders, or large round bales of hay, also make perfect places to lay their eggs. Making it all the more likely you will find them indoors trying to bite you! So there you have it! House flies don’t bite, but you can get bit by a fly in the house!

I grew up in Bath, Maine in an upper lower class family with 3 step sisters, a step brother, and a little sister. After high school I spent 3 years serving in the USAF at Elmendorf AFB in Anchorage AK. I've competed in, and won, demolition derbies. I've competed in, and never won, stock car races. I am the 47-year-old father of an 11-year-old boy who is pretty sure he is smarter than I ever was. We live on a little less than an acre of land in a 1973 mobile home in Stetson with my wife Jen, some cats, a few chickens, and rabbits, and a couple of goats. I hunt, fish, camp out, dabble in photography, gardening, and I cook in variable degrees of near success.
