It attracts not only very flies, but also pesky pumpkin beetles Japanese beetles, which are all over my garden. This makes my gardening experience much better. You can use almost anything that stinks as bait, the stinker the better.
I used stinky fly bait, as seen on YouTube, and added cow dung to the broth, which worked perfectly. Keep the bait well stocked and damp, and the flies will keep coming in.
It was up and running within minutes, and we've caught a dozen. I put dog shit and water as bait.... That sounds gross... But it worked so well!!
The product works well, but you have to have the bait.Recommend!
Love these traps! The don't smell and unless a racoon gets to them, they last all season! The hardest part is remembering to refill the bait bowls. We use leftover food with plenty of liquid in the bowls. Liquid can be water but watermelon juice is very popular with flies!
