The leak-preventer systems 

Last update: 20/06/2008

To date, there are several systems of fence which I will try to present to you.
Each method has its advantages and its disadvantages. I will detail them as much as possible.

The electric fence:

Easy to set up, it consists in fixing a ribbon made up of several wire stainless (4,8, etc.) on a support (insulating preferably). These wire are then connected either to a transformer (12V AC) or to a battery of car (13,8V cd.).

We can also carry out an electric fence without ribbon:

Some examples of electric fences (Thank you for Backo and J.Matéo for their collaboration):

The battery:
  • current capacity in the event of cut of electricity. 
  • facility of displacements.
  • high amperage.
  • to think of checking the load.

The transformer:
  • less expensive than the battery.
  • deliver AC current.
  • it's needs a source 220V AC in the vicinity (EDF).
  • do not function in the event of cut this current any more

The AC current (AC) seems stressless for the snails than D.C. current (cd.).
Personally, I prefer the transformer system provided with the electronic chart which makes it possible toppel over towards a spare battery in the event of cut sector (uninterrupted food). This chart will be described in electronic section of this site.

In the 2 cases, electricity have the disadvantage of roasting small snails (youthful). Moreover, the slugs not being able to curl up in their shell, roast on the ribbon and cause a "bridge" that the snails will not fail to take. 

In addition, the snails start to drool when they are made "tickle". The drool remains then on the electric ribbon. This ribbon should be frequently cleaned. It's then slightest things to do for our adored snails !!

The chemical fence (grease + salt):

The mixture consists of 50% cooking salt and 50% of grease. We can also add soft soap.
The "paste" obtained is deposited on the support inside the "escargotière" (wood, concrete, asbestos cement, etc...) on a 5 centimetres height tape approximately.
This method is satisfactory, but it's necessary to think of protecting this "ribbon" against water (sprinkling and rain).
A turned over gutter can make the deal perfectly. In this case, the paste is fixed on the internal part of the gutter.

The copper fence:

The principle (I did not check!): copper reacts with the drool sweated by snails to form an electrical current which pushes back them.

The mechanical fence with plastic film:

On the wall of the "escargotière" a cleat out of wooden is fixed which a fine plastic ribbon approximately a 10 cm is fastened height.

The mechanical fence with aluminium mosquito net:

Principle:  an aluminium mosquito net is posed on a cleat . It is necessary to withdraw two horizontal lower wire of the band over the entire length and that's all folk's !
Moreover, you can add electricity on the mosquito net to increase the system effectiveness (it + on netting, - on the ground).

The watery fence:

Principle: the "escargotière" is surrounded by of a small brook which the snail will not cross! This principle can be carried out with gutters for example.
