I've only found these at tractor supply. The flies go in and can't get out. They drown. Seems non glicky. You add the powder (which smells like rotten eggs) to water and pour it in. Add water as needed. As flies die, they become the attractant for more flies.
It's amazing the difference this has made. My cows had thousands of flies on them. This seemed to put them in check.
I thought about that also. Anything that attracts flies can be put in it. I confirmed the main ingredient is eggs. Problem is the smell from dead flies. I got dry heaves when I emptied it. The smell of death x5. Emptying sooner would resolve this issue.
When I emptied it I left a little dead fly juice in the jar and added water. Today, I saw 2 buzzards flying low. I walked over and it was obvious why they were there.
Maintenance is needed cause it gets stinkier as the flies decompose
That's kind of the problem. Not very practical to use flys as feed if it is disgusting to harvest them every time. Do the flys stink because they get wet and start to rot?
I came across a really disgusting video of a fly trap on YouTube and was trying to think of a way to lure the flys in but have them get stuck in a second container or area that would be dry so they would just dry out. Don't know if this would work or not.
Was sort of thinking a screen or something so the flys would smell the liquid but not come in contact with it. Although I don't know if the humidity from the liquid would condensate and cause them to rot anyway.
