Bests & Worsts Reviews from Amazon

I have LOVED these in the past when you filled it yourself and the liquid was slightly yellowish but the new red liquid that comes in pre-filled containers does NOT work in the slightest. The old ones would gather fruit flies by the hordes and clear up any problem in record time, the new red liquid ones can't even get a fruit fly to stop by. I had some old ones left and put them out and they collected a bunch of ff even though they were quite old. The new red ones are still waiting for a ff to find them. Disgusted at the product change and have gone from recommending them to warning against the new product.
