From the University of California IPM webpage: The predatory decollate snail <https://ipm.ucanr.edu/PMG/NE/decollate_snail.html>, *Rumina decollata*, is used in Southern California citrus groves and other crops, gardens, and landscapes to control <https://ipm.ucanr.edu/PMG/R/I-SM-RDEC-BH.009.html> young brown garden snails and can provide very effective biological control. Decollate snails can also feed on seedlings, small plants, and flowers, although they are less problematic than brown snails. Snail baits will kill decollate snails. You should not use baits where these predators are active. Because of the potential impact of the decollate snail on certain endangered mollusk species, it legally cannot be released in California outside of Fresno, Imperial, Kern, Los Angeles, Madera, Orange, Riverside, Santa Barbara, San Bernardino, San Diego, Ventura, and Tulare counties. *Even in counties where decollate snails are permitted, they should not be introduced in or near natural areas because of the potential danger to endangered native snails* We used these tiny predatory snails at my folk’s place in Northern San Diego County and they worked very well. The European snails would disappear for a few years. Eventually, the population would rebound and we would just get more of the predators. It worked way, way better than snail bait. Please note, however, that these snails are not to be used everywhere because of the potential of impacting native terrestrial snails. Will have to peruse the scientific literature to see what testing was done prior to giving the OK to sell these as biocontrol. Will post what I find out, but it may take a few days. Rats really like snails, but not a control organism I would recommend! I’ve torn out big expanses of ivy used as ground cover (primo rat habitat) and found tons of empty, chewed on snail shells. > > ------------------------------ > > Message: 2 > Date: Wed, 23 Aug 2023 18:39:12 +0300 > From: Shmuel Silinsky <gardenbetter@gmail.com> > To: Pacific Bulb Society <pbs@lists.pacificbulbsociety.net> > Subject: Re: [pbs] Banana slugs > Message-ID: > < > CACHBJeFzt1YM2p-ByMUf5XaRRJ7V4gBxbB_LU+UOiyMNtFtArQ@mail.gmail.com> > Content-Type: text/plain; charset="UTF-8" > > Our major snail problem is millions of the large European snails.
