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!

    • Hi Brent…it’s the bubbles that kids use. When I said “bubble juice” I was just referring to the remnants of the bubble solution that was left over.

  1. Thanks for the info.

    As for the mosquitoes, Purple Martins are one of the best mosquito killers in existence. I’ve got Martins and a pond and never get mosquito bites during the summer.

  2. I saw this on one of my facebook friends pages. There is a picture of the trap empty and full of mosquitos. Don’t know how to share.

    Items needed:
    1 cup of water
    1/4 cup of brown sugar
    1 gram of yeast
    1 2-liter bottle

    1. Cut the plastic bottle in half.
    2. Mix brown sugar with hot water. Let cool. When cold, pour in the bottom half of the bottle.
    3. Add the yeast. No need to mix. It creates carbon dioxide, which attracts mosquitoes.
    4. Place the funnel part, upside down, into the other half of the bottle, taping them together if desired.
    5. Wrap the bottle with something black, leaving the top uncovered, and place it outside in an area away from your normal gathering area. (Mosquitoes are also drawn to the color black.)

    Change the solution every 2 weeks for continuous control.

  3. The flies wings get covered with the soap and they get stuck. Sugar water with a few drops of dishwater soap also works.

  4. Try this amazing fly trap I use. It really works! I have same problems with flies even outdoors and tried several remedies as well but so far ive been loving this product and will continue to use it check and see if it works for you too
