Bests & Worsts Reviews from Amazon

I bought 4 packs, total of eight for two acres. Analyzing the contents, it is yeast, sugar and probably borate. The concept is you pour warm water into the yeast to activate it. The yeast feed off the sugar and emit C02. Mosquito's fly in and drink the water/borate and die. This concept has been around quite a while using a pepsi bottle, google it. The thing is, the pepsi trap, like this, under real tests do not work. The container is a long skinny smooth tube. It has six tiny holes up on top. Supposedly, the mosquito will, somehow, detect the C02, fly up to the tip of the smooth plastic tube and squeeze itself in this 4mm hole, tucking its legs and body in as it slides itself in this pin hole. Then once inside, fly down the narrow shaft take a drink of water, fly up the thin shaft, and once again tuck its legs in and squeeze itself through to fly away. This concept is so far fetched. I would like to see real proof than unproven customer reviews. It would be great that the manufacture would show real data and show mosquito accessing these tubes as they say. I opened one up and poured the contents out. Only bugs I see are fruit flies and a few house flies, but not mosquito's. I will take pictures next time. I find it interesting that the manufacturer mentions that the mosquitoes fly out, thus you will not see any mosquitoes trapped in the tube. Yet, fruit flies, and house flies, which are notoriously way better flyers and can crawl, can not find their wait out of the trap.
