Works OK (for a while), but you could do better
on November 8, 2009
What you get is two McCormick's spice jars (exact same jars as used for spices) and two packets of bait. Add water and they will attract fruit flies, for about two weeks, when the bait will grow a thick, spongy greenish-white fungus.
There is no poison involved - the fruit flies enter the spice jar through the holes, being attracted by the scent of the bait, but once they enter they are not smart enough to figure out how to get out, and eventually drown.
About a week after I bought these traps, I used some apple cider vinegar and set the bottle aside. I noticed that many fruit flies were attracted to the bottle, where some vinegar had dribbled. The vinegar bottle was only a few inches away from the spice-bottle traps, so apple cider vinegar must be very appealing to fruit flies, as many flies ignored the trap and were attracted to the vinegar bottle instead.
So I made my own simple and inexpensive trap by taking a small jar, punching a few holes in the top (about the diameter of a pencil) and adding apple cider vinegar. It works GREAT (as good as the commercial trap), and the vinegar does not spoil or grow fungus, so it lasts a LONG time. And, the acid of the vinegar will actually dissolve the fruit flies (after about 12 hours), so it doesn't make this nasty mess.
I give two stars (instead of one) because it works as described, but I would not recommend it to anyone.
