    Maybe useful info for some of the gardeners:

    Pest control: Wake-up call

    Existing commercial repellents for slugs and snails leave crop residues that are
    not permitted by food-safety agencies. But caffeine — classed as 'generally
    recognized as safe' by the US Food and Drug Administration — has
    now been shown to do a similar job. Slugs are killed by a 1% solution of
    caffeine sprayed onto leaves, and concentrations as low as 0.01% significantly
    reduce feeding. In orchid snails, a 0.1% solution is enough to make the
    heartbeat weak and irregular. It is not yet known how caffeine exerts its effect,
    but its high solubility in water — a key component of molluscs' locomotor
    mucus — could make it an effective contact poison.

    Now I know what to do with the grounds from each pot of coffee we brew. Thanks, Catcher!

    btw, do you plant a lot of rye? Just wondering.
