A friend gave me some lengths of Phosphor Bronze draught excluder he
found in his garage - apparently very popular in the 60s.

It is something like 95% copper.

I thought that it would be perfect for nailing around my raised beds
as a slug deterrent: so I tried a little experiment.

I cut four strips of the material and nailed them to a flat piece of
wood in a square. I then put a slug in the middle of the square. It
slowly made its way across the square - and then straight over the
"copper" strip.

Does anyone use copper as a slug deterrent and do you think it makes
any difference?


I read ages ago that dissimilar metals can cause an electric current.
(basics for a small charge). Elecrolite static charge? We can get corrosion
from this and during this process a polaric field can be obtained. It is
arguable that this is how life was formed with the aid of liquid water.
