Where have the houseflies gone? September 3, 2014

Our friend Ben was busy in our home office when I noticed a small, winged insect buzzing around. At first, I thought it must be a young housefly, those annoying nuisances that always seem to find their way into the house in warm weather, no matter how hard you try to stop them. (Thus flyswatters, flypaper, and the like have been with us for a very long time; try as we might, we just can’t seem to keep the critters out.)

Eventually, I realized that the buzzing noise wasn’t housefly-like; the insect was something else. But it made me realize that, unlike past years, I hadn’t seen a single housefly, in or out of the house, this year. Not one. I wondered if America had been struck with housefly decline. For once, global warming couldn’t be to blame, since the flies love hot weather, but maybe last year’s super-cold winter killed them off. Or maybe, like the poor honeybees, they’d been struck with some dreadful malady. Our friend Ben decided to head to my good friend Google to find out.

“Housefly decline” didn’t bring up anything, so I went on Wikipedia to see what it had to say about houseflies. Yowie kazowie! I learned three things I didn’t know about houseflies. First, that the females can lay 9,000 eggs (yes, you read that right) over a lifetime, producing many, many generations in a single year. (So, where are they?!) Next, that once flies emerge from their pupal cases, whether they’re huge or tiny depends on how much food they got as maggots (which feed on rotting food and rotten or decaying flesh, as well as manure, yum). In other words, little flies don’t grow into bigger flies; little flies just didn’t get enough to eat in their maggot (sickening white, worm-like) stage. And last, that houseflies can carry diseases like cholera and tuberculosis (and plenty of others).

That’s sort of the opposite of all those movies like “Gladiator” where you see maggots eating away at rotting flesh on living men and saving them from infection, gangrene, and death. Which reminds me of the fourth thing I didn’t know about houseflies: They’re not just here in the good old USA, but occur around the world, and apparently always have.

So what’s become of them? Have you noticed fewer (or no) houseflies in your home this year? Let us know. I have to say, this is one creature I wouldn’t mind seeing on the decline.

I just realized that you’re right!!! No flies!!! And I’m in Georgia, having moved down here from Felton, PA in November ’13. I detest flies, so now I see why I’m only miserable due to this Georgian summer and the no-see-ums… But not due to flies!!!

Thanks, Sandra! I guess it’s not just us! As for moving to Georgia, we’re ex-Nashvillians who moved to PA to escape the unbearable heat and humidity of Southern summers, so we sympathize with your plight. But now it seems like PA is almost as bad! Every summer, we fantasize about relocating to Nova Scotia…
