Less good experience to share:
I tried the sock method with a cold oil infusion (almond oil with Mugwort) and a mouse got to it, threw it over and ate/drank it. There is a big ragged hole in the sock and a stain on the surface where I put it. Maybe worth to share as mice are very common here in Amsterdam, and they eat everything, especially fatty stuff..
