Hi,
We saw somewhere on the box that the average garden has approx 50 slugs, well, we put down six slug pubs, [fresh beer it has to be

], and the following morning I counted 96 of the drunk little blighters, from 5mm up to the monsters.
Definitely a working deterent, we use the cut off top and bottoms of plastic coke bottles sunk flush into the ground, and I ask our local hostelry to save us a quart coke bottle of beer every time they clean the pumps [NO I'm not allowed near it

].
Somehow this thread has drifted off ponds, perhaps it should be moved.
Max.
