Commentary

Hi Susan, thank you for your report. Apparently, the snail you are describing is the he brown garden snail (formerly known as Helix aspersa). It was introduced as an escargot delicacy in California in the 1850s where they are now a major garden pest an a pest in the citrus growing industry. The UCDavis site lists ducks as a good control option.

Thanks again for your report - it sounds like considering a backyard duck or two may help solve the problem.
