The swollen wool pellets form a felt like mat that absorbs moisture from the slug's foot, thereby making it difficult for the slug to travel across. It also contains abrasive particles which irritate the slugs food, physically deterring the slug and creating sn100 percent natural barrier. It is excellent at keeping the surface of the pot dry but retaining the moisture beneath. This also means that weeds have difficulty germinating on the surface and frequency of watering is cut down due to reduced evaporation.
