Beer? I'd have to buy an entire brewery. Ok, a whole truckful.
Last year I thought I would try handpicking them. A nice, organic alternative, right?
Went out after supper, armed with a large bucket of soapy water and tongs. Counted as I picked 'em and stuck 'em in the bucket. Lost count after 500. And I did this for nearly a full week, and it made no dent in the population.
Major eewww!
They prefer to eat dying leaves (weeds thrown on the compost heap, the aged leaves of the spring flowering bulbs) but when there are so many slugs and snails, then they start eating everything else, too.
