drastic drop in fruit flies since I put one over sink and one over computer...

While I haven't tried this particlua device. IT's very close to what I have found that works well. One don't throw away empty beer cans or wine in the house. Two eat your bannas within one or two days and throw the peeals outside. One or two can make thousands in just a few weeks. People make traps out of old beer and a cu open soda bottle cut about 3/4 down and take the top and stick it in the remaing part of the bottle with old beer or apple cider vineger or apple cider and a drop of dishwashing soap.. What I found best is to use everything. clean your sink with baking soda and vinerger to make it foam out the top. . The best way is to take a smaller piece of plastic tupperware or simular and put some apple cider viner or cider. Then this is the nasty part is unstrip a fly paper strip and add a 1/2 oz of wieght at the bottem just to keep it unwraped and wide as possible and hang it just above the cider mixture. The misture may kill ten or twelve but the fly strips used in barns and get that sticky stuff all on your hans. These knats are smart and will investigate the apple cider before going in. They will fly around it for a good while before testing the trap or bowl. I caught twenty in the mixture in 2 days at the same time I got over 200 of them on the tape I hung just above the bait. So far I'm at close to catching 1000 of these annoying things in less than a week. They are busy checking out the bait and unsuspectingly get stuck on the sticky stuff. Still have a few flying around but almost all gone. It's ugly and cruel but it's better than having them in the house.
