Fruit fly trap with CD-ROM

That vinegar, stale beer or wine attracts the beasts, would have to be known by the previous tips. A few drops of Spüli, is nothing new.

My success tip:
The above mixture in a glass, on it an old CD-ROM. The critters are attracted not only by the smell, but also by the brilliance of the CD-Rom. They crawl through the hole in the middle, do not find out anymore and drown. In any case, this version has the advantage of working without any chemistry and glue, you do not have to touch anything disgusting. The bodies are simply disposed of including the solution in the toilet and the mixture is made new.

You have to hold out a good week.
