Snails traditionally breed in March so if you start your
seek and destroy campaign right now and persist in doing
so for a couple of years to come, it is almost a sure thing
that your escargot population will visibly decline.

I second the Sluggo suggestion; we have used it last year
with great success and our Hostas among other plants
were happier than we have ever seen them. And there is
also the flashlight and empty can brigade solution.
Get out after the sun goes down, empty can in one
hand and flashlight in the other and collect the escargot
by hand, cheaper and no damage to the environment
except perhaps to one's perception of the garden ;)
