Fish aren't much of a stretch either, although developing nets and hooks must have taken plenty of time and head-scratching. Given hunger and a spear, everything falls together quite nicely, especially when you've got fire in the picture. You don't have to wonder, about the first person who ate a duck or a buffalo.

The Living World of Molluscs: The Brown Garden SnailĬanada Food Inspection Agency: Helix aspersa (Muller) - European brown garden snail. University of Florida and the Florida Department of Agriculture and Consumer Services Featured Creatures:Brown garden snail There are some useful sites to gather more information on this snail species: Many people utilize chickens or geese to manage snails and slugs. Naturally occurring enemies of snails include ground beetles, parasitic flies, and predators such as frogs, lizards, and birds. , a biological control agent used in Europe, is not registered for use in the US and prohibited. Similarly beneficial nematode, Phasmarhabdis sp. The biological control agent, decollate snail, Rumina decollata, is considered a threat to native slug and snail species as well as a direct plant feeder and banned from shipment to the Pacific Northwest. Snail traps, both commercial and homemade, often use a beer-based attractant to lure snails inside to drown. Reduce habitat by eliminating weeds and clean up debris under which they can hide. Hand picking and disposal of the snails can reduce populations as well. Alternative chemical options include: iron phosphate baits (several brands), some botanical products such as limonene (Orange Guard), and repellent botantical products such as cinnamon oil (Slug and Snail Away).īarriers such as copper strips are effective although expensive. Caution should be used with these baits as they can be toxic if ingested by pets. Landscape options include metaldehyde baits (several brands). Recent trials with another snail species, amber snails, here in Oregon showed good efficacy. It is a combination product with the active ingredients: capsaisin and allyl isothiocyanate, an essential oil from mustard plants. Dazitol is another alternative chemical option for nurseries. Treated snails tend to wonder away so treatment evaluation should be based on reduction of feeding damage. This causes the snails to stop feeding and eventually to die by starvation. It must be ingested for activity, which includes damage to the snail's crop and hepatopancreas. The active ingredient is naturally occurring and OMRI approved. An alternative to carbamate products are baits containing iron phosphate (Sluggo). Choices include carbamate molluscicides such as methiocarb (Mesurol), a restricted use product, and metaldehyde sprays or baits (several brands). If detected in a nursery, this species must be eradicated and chemical control is the most common tool for this purpose. Management of brown garden snail in nurseries generally requires a focus on prevention, primarily with inspection of incoming plant material and quarantine. Closely related snails of concern are the European apple snail, H. The brown garden snail feeds on a wide range of host material and can commonly be found climbing into trees and shrubs. This snail is reported to cost the state of California 7-10 million dollars every year.Ĭurrently brown garden snail presents the greatest risk to nurseries given its status as a quarantine pest and its establishment in sites around Oregon and Washington. In the United States, it is reported from California north to British Columbia, Canada, in most southeastern states and along the east coast north to New Jersey. There have been introductions of this species into Argentina, the Atlantic Islands, Australia, Chile, Haiti, Mexico, New Zealand, and South Africa. This snail species originates from Britain, western Europe, and along borders of the Mediterranean and Black Seas. Brown garden snail, Cornu aspersa (formerly Helix aspersa, Cantareus aspersus, and Cryptomphalus aspersus) is a member of the family Helicidae.
