Basil in the kitchen in 24 exempt from all black flies!

The absolute hammer! We have a basil in the kitchen are and eventually gabs with each casting a black cloud of small flies. Then they put adhesive and innerhalbt of 24 in the pot were all (!) Of the fly on the Klebeflaeche and no longer flew. Seems to be well sustained, since 2 weeks is now resting in advance and even though I've only used an adhesive. Those things are quite large, but neither looks bad (ok if the full stick with flies and a I do not like you can do that throw away), yet ists really impractical.
