I am so doing:
The trap was placed there where I suspected that the critters have their path. Tucked placed and camouflaged well with hay, branches and grass. Honestly, I was from the beginning not sure if this will work at all since you hear it are intelligent animals and as a trap quickly recognize them as such.
Ok, the next thing I had the case just a few days in the garden allowed to stand, of course not activated! Just around the animals get used to it.
The next step was time to put a bait. For me it was a raw egg. The egg was certainly four or five days in the case untouched. Have already garnicht longer believed but the bait was really eaten. Then I gave each day a new bait into it and it was the next morning getting away.
Now it was to be placed on the time the trap sharp. No sooner said than done ... the next morning the trap was triggered, full of excitement I approached the thing. The disillusionment followed at the same time, the trap was empty and apparently triggered itself. Hm ...
I even started a trial, same procedure. It took a few days back but the wait was worth it. At about midnight I was awakened by loud cries of the martens. I had a prisoner, with this case, could not believe it somehow but it worked. Had the case been larger I would have the 2nd even caught ;-)
So, bring a lot of patience, I think it's worth it!
