Pests and Diseases: Easy House Fly Trap

Today’s Pest and Disease topic isn’t one that affects your plants but it most certainly affects you. It’s about flies. Those nasty, little bothersome pests that circle your head and seem content to make your life miserable. You swat at them but you can’t ever seem to kill them. They are the bane of many picnics and outside gatherings and can cause your outside dinner to quickly become an indoor one. Instead of looking at their life cycle and discussing what they are attracted to, I thought that we would cut right to the good stuff: killing them!

I discovered an easy house fly trap strictly by coincidence. My daughter and I played with bubbles one evening and we left the last little bit of bubble juice in the bottom of a yellow tray. (UPDATE: bubble juice is just what remains in the bottom of the tray once you finish blowing bubbles) When I went outside the next morning, I discovered this:

Nineteen dead house flies. And the worst part is that I hadn’t even seen flies flying around the day before. Where did they come from? I’m not sure but they found us. I did some research and everything I read says that house flies are attracted to blue. In fact, the studies show that they prefer blue to yellow by quite a lot. Not at my house. Here’s a picture from the same morning.

No flies. Everything else was the same…bubble juice was left in the bottom and these were virtually side by side on the table. I think that makes for an interesting comparison and an easy house fly trap. Now if I could only find an easy trap for mosquitoes. I have a swampy area behind my house and we are the closest food that they have. There are many summer evenings where we can’t even be outside, they’re so bad. Perhaps a Mid-Atlantic Gardening reader has some crafty mosquito trap that they would like to share. If you do, leave me a comment below or e-mail me at Now if you’ll excuse me, I have to go put a little bubble juice in a yellow tray outside. Happy gardening!
