I've been looking for bait ideas. I refit those $5 bag type traps you can buy at the hardware store with clear one gallon jugs. It works but is not all that mechanically sound when hanging in a tree. This bucket scheme looks interesting. I have have always wondered though whether the trap was really catching as many flies as it seemed or whether they were just reproducing, living, and dying inside the trap. I'd like to to be able to kill them once they enter to eliminate that possibility. Dave |

Bob The bait in the trap is a foul broth, the stench of which attracts the flies, and maggots can always be seen living in it. |

If the purpose of the bait is to smell bad. Can you put a piece of screen
over the bait cup. This would let the odor out, but not let the flies in to lay eggs. "Bob Engelhardt" wrote in message ...

Can you put a piece of screen over the bait cup. This would let the odor out, but not let the flies in to lay eggs. After re-reading the instructions I finally see what is being suggested. The trap merely sits over the bait cup. He doesn't mention adding a screen over the bait cup but that would be a trivial addition. Interesting that the trap does not catch the flies on their way to the bait but only as they try to leave the bait or as they search the area around the bait. |

A curious thing about flies (and other daytime flying insects) is that they will usually fly towards the most light. So lots of bug traps work by drawing the flies in through a small dark opening (usually by scent) and then having a bright area above which they will instinctively fly towards once they're done with the bait. There are hundreds of designs that use this principle. One of the most elegant I've seen was a sphere of brass mesh with a flared hole in the bottom that sat on little legs over the bait dish. Looked like an old time hot air balloon, was nice enough to be part of the centerpiece on a table and caught yellow jackets like crazy. Jim |

Now I don't know what to do with it. It is so light it will be blown over in any windstorm. Also the dogs might knock it over. I guess I will strap it to a fence post. Don't know if I want to put feet on it or just hang the bottom under it on wires. |

Well that "bait" sure sounds interesting!
If you cut way back on the yeast and add more sugar you get two of the normal ingredients for homebrew. Now just add a little flavoring and let sit for the same amount of time. Bottle. Enjoy. :-) OK. I missed a couple of the fine points, but... DOC "Dave" wrote in message om... Gunner wrote in message . ..

I've settled on a mixture of apple juice, honey and yeast in my traps, it seems to simulate over-ripe fruit and they love it. I've had them fly into the traps while I'm hanging them in the tree, yikes! Brian, in Cedar |
