Helps not

Update (29/11/2014):
Now some time has passed again and unfortunately I have to say that the bait boxes helped only very briefly. Really I have peace only since I switched from this bait boxes on Ardap (Quiko Ardap Ungezieferspray 750 ml). Ardap attracts the silverfish and immediately begins to work as soon as they come into contact. The silverfish experience thus unfortunately a very agonizing death by paralysis but c'est la vie ... eventually has you fed up with the critters and then one all means are acceptable.

First of all: This Bait combated only the symptom. Who does not correct the cause, will achieve little success.

I can not emphasize this enough: just to fight the symptom, not enough. Before bait boxes, etc. anschafft itself, you have to investigate the cause, otherwise you waste only his money.

The causes in my apartment had a large area broken silicone joints and parched outflows guest toilet.

After the apartment completely vacated and * all * joints and cracks (even behind furniture, etc.) were closed with fresh silicone, there were noticeably fewer unwanted guests that night scurried along the ground.

The bait boxes (in total I bought 10 pieces) have eliminated the still remaining silver fish with me. After a few days already silverfish lay dead near the prepared bait boxes ..

Now in the drains i cant regular hot water directly from the kettle and closes it afterwards. This also helps prevent unpleasant odors.
