When designing an escargot farm, some suggest that a 7.5 cm wide strip of copper will keep snails in external enclosures because they get a slight ‘shock’ when they try to glide over it. This, I assume, has an electric fence effect discharging [static?] static electricity as the snail slime touches the copper.

I’ll have a go at this idea at the HoBB to see if it works so if you have or know of any 7.5 cm wide copper strip, contact me. I have tried barriers of curved overhanging metal and even teasels but so far not discovered a barrier that works on all snail sizes and in all weathers.
