Slugs

Use coffee and tea on the slugs. Caffein concentrations of 5% will kill them while the .25% concentrations of coffee and tea will deter them. Interesting note last year from usda research.

Maybe my son's Jolt Cola can come in useful? :-))

Hmmm, from what I have read, coffee doesn't contain enough caffeine. Here is a link I found in one of my saved messages:

Another message contains info from The Garden (monthly journal of the RHS):

"It basically says that 'a spray solution of 1-2 percent caffeine kills large slugs, and repels them when concentrations are as low as 0.1 perent' ... 'It is not known how the caffeine kills the molluscs, but it seems to damage the nervous system.' Unfortunately, they don't say how to come by caffeine - but they do say that 'a cup of instant coffee contains about 0.05 percent caffeine'."

I don't know if the caffeine percentage is higher for brewed coffee. The link above says expresso has 2 percent.
