The Brown Garden Snail (Cornu aspersum), also known as the common garden snail, is one of the most widespread snail species found in gardens and agricultural areas. Native to the Mediterranean region, it has spread throughout much of North America and other parts of the world through human activity. This species feeds on a wide range of plants and can become a persistent pest in gardens and landscapes.
Quick Facts
- Group: Gastropod Mollusk
- Habitat: Gardens, orchards, vineyards
- Diet: Leaves, fruits, vegetables, ornamental plants
- Status: Common garden pest
Identification
The brown garden snail has a rounded spiral shell that ranges from light brown to tan with darker bands. Adult shells usually measure about 1 to 1.5 inches across. The soft body extends from the shell and includes two pairs of tentacles used for sensing the environment.
Like other snails and slugs, the species produces a visible slime trail while moving.
Distribution
Brown garden snails are now found throughout many temperate regions worldwide. They thrive in moist climates and areas with dense vegetation.
Life Cycle
These snails are hermaphrodites, meaning each individual can produce eggs. After mating, eggs are laid in moist soil where they hatch into small snails that gradually grow and develop shells.
Pest Status
The brown garden snail can cause significant damage to vegetables, flowers, and fruit crops by chewing holes in leaves and feeding on ripening produce.
Prevention
- Remove debris where snails hide during the day
- Water plants early to reduce nighttime moisture
- Use copper barriers around garden beds
Control
Hand removal, traps, and snail bait products are common control methods for garden infestations.
