Snail trap

Cut the top of a 2L plastic bottle about 6 cm in height, and then cut out small tunnels on the bottom frame for the snail to crawl through.

The reason we have it as this is to prevent water/rain flowing into it.

Cut the bottom of a 1L plastic bottle about 1 cm in height.

Cut out a circle or square piece of wood.
Screw the plastic food tray into the middle.
If you want you can use a large nail, this will also be used to "plug" it into the dirt, so it don't topple over if there are alot of wind.

Then Glue or screw down the Top.

Whenever you need to refill it, unscrew the cork at the top and fill it up with snail repellents
