“Garden Snail” or the “Helix Aspersa” represents terrestrial mollusks phylum of gastropod class biologically. It is one of the most adaptive species and has been introduced widely and naturalized in almost every part of the world. However, Garden Snails are native to Mediterranean region, Western Europe, Northwest Africa, Asia Minor, and The British Isles.
Despite its being considered as an edible species it is regarded as a “pest” when it is referred to gardening. If you are a gardener then treat the “Garden Snails” better as a pest and not as an edible tasty, delicious food item. Some people also like to preserve mollusks including garden snails as they look good and pleasures. But for a gardener the garden snails are no less than an enemy.
An adult garden snail will be having a hard, thin calcareous shell with a diameter of about 25-40 mm and almost 25-35 mm height. A typical shell will also have four or five whorls. Color however could vary and the garden snails may show varying shades as well. Normally these are dark brown or chestnut in color with yellow stripes, flecks, or streaks.
Garden Snails generally have smooth, soft, and slimy body with brownish-grey tint. This is what you must have noticed in your garden also. When inactive or protective the animal withdraws itself within the shell. Aperture or the mouth of these shells gets closed when faced with adverse weather like extreme cold or dry summers. When the animal becomes active its head and feet come out of the shell.
Head of the garden snails have typically arranged four tentacles. Two of these tentacles bear eyes of the animal. These are upper tentacles and are longer also. The lower tentacles pair is smaller, tactile, and functions as sensory organs for the animal. These lower tentacles can easily be retracted in to shell by the animal.
Immediately below the tentacles there exists animal’s mouth. Mouth contains a chitinous radula. It is a material that the snails use for scrapping and manipulating food particles. This is primarily responsible for any damage to your plants in the garden as snails would use it for grabbing their food from plants.
Muscular contraction of foot and its expansion created a locomotive action and this is how snails move. During these locomotive action snails also secret mucus that keeps the friction at minimum. Snails can attain a top speed of 1.3 centimeters per second.
Reproduction in garden snails is hermaphroditic, producing both male and female gametes. After exchanging sperms both male and female snails will dig a nest in the soil and then deposit their fertilized eggs there. It takes almost two weeks that the young garden snails emerge out of the nests. Further one or two years it will take them to reach at maturity.
As a gardener you should be concerned over the existence of these garden snails in your garden. Reproduction of garden snails would seriously affect the quality of soil in your garden also.
Garden snails are herbivorous. They cause damage to numerous types of plants including fruit trees, vegetable crops, garden flowers, and cereals as all these are their food materials.
So, if you have noticed the presence of garden snails in your garden then you should consider ways to eliminate them and finish up with any chances of further growth of their populations. You must have a garden snail’s free garden.
I hear the best way to keep away snails is to encourage natural spaces. Animals will move in there like hedgehogs, slowworms and frogs. All three of those animals LOVE eating those nasty snails!
I just pick up the snails in the evening, when they come out and toss them over the fence where they land on something solid. I figure the scrubjays will appreciate them.

Yes, it is true if you live in open country. But most of us live in the urban area where we do not see those animals alot.
