In the summer, it seems nearly impossible to open your door without a housefly inviting itself into your home. Then, after a sad attempt at trying to swat it away and failing, you're left preparing dinner as the fly buzzes and bounces against the glass window. Suddenly, the noise is gone, and you look down to find the fly sitting on the chicken you were making. Do you throw that nearly finished meal out? Technical training managers Dave Lofquist and Tommy Olschewske at explains what to do about flies.
1. A housefly will likely die on its own from stress.
The interior of a home can be disorienting and stressful to a housefly, says Lofquist. If you've ever seen a fly bouncing on a window trying to escape, that's what will eventually cause its death. These flies aren't meant to be in air-conditioned environments, which can also contribute to them dying. The longest a housefly will last inside is about two weeks.
2. Flies don't vomit when they land on you.
The myth you may have heard in middle school has been busted: "Flies don't have teeth. Instead they have a spongy mouth part that soaks up food," explained Olschewske. Since houseflies don't have teeth, they'll vomit on the food to make it wet and then they'll dissolve it and eat it. A housefly doesn't consider your shoulder as food — they're more into feces and trash — so no, it's not going to vomit if it lands on you.
3. But if a fly does land on you, wash yourself. And don't eat anything that it touches.
"The biggest concern a person should have is that when a fly lands on your counter, it was probably on something decaying before," said Olschewske. Olschewske said the most concerning part about flies is not knowing where they've been, but knowing what they're attracted to. When asked if the three-second rule works at all here, and Olschewske said, "I'm not going to eat it." He adds that if he goes to a restaurant where he sees a few flies, he's walking right out.
4. The best way to clean your sink to avoid flies and gnats is with vinegar and baking soda.
Olschewske swears by three scoops of and some when it comes to cleaning the sink, and he'll never use bleach. The foam that forms from the baking soda and vinegar is crucial because it'll stick to the inside of the pipes and really clean everything out.
5. Houseflies thrive in anything wet and warm.
The cooler and drier, the less likely houseflies will be there. In addition to sticky temps and water, the experts at Arrow Exterminators say that garbage and pet droppings are draw flies in. The winged pests want to nest in pet feces or in the garbage under your sink — they're not just coming in because they smell the pie you just baked. Pro tip: Scrub your garbage can every once in a while with warm water and soap, to get rid of any food residue.
6. If you go away for a week, don't forget to do this one thing.
First things first: Get rid of your trash and clean your garbage bin before you leave for a summer escape. Then, the major no-no: Don't turn the A/C all the way up to 80-something, which is a common mistake. Lofquist says to leave it in the mid-70s, because the higher humidity, the more likely flies are to nest while you're gone.
7. While you're gone, they could lay eggs.
Let's say you leave garbage in the sink while you're gone. A fly might come in and lay some eggs. Olschewske and Lofquist say flies are always seeking places to do this, and that a housefly will lay 500 eggs in its lifespan. Anything from a garbage to a dead animal in a crawl place or attic can cause this to happen. If it does, they say to contact a specialist immediately.
