These small snails will actually attack and destroy the common brown garden snail and its eggs. And rather than slime around on walkways, they prefer to burrow just under the surface, seeking out their prey and laying their own eggs (about 2,000 in their lifetime). If Decollates can’t find brown snails to eat, they will survive on dead leaves and debris, but they always prefer snails. Each order includes 50 adult snails. Decollate Snails are only allowed to be shipped to Southern California addresses, ZIP codes 90000-93499.
