Snail barrier sheep wool

In the vegetable bed, a constant battle is raging. When it comes to lettuce snails can be irritable foes. Knowledge of their weaknesses is essential to defeating them. One of the astonishing vulnerabilities of a snail is its tell-tale slime: in addition to keeping the mollusc moist and protecting them against pollutants and injuries, it provides them with the means of locomotion. Without this "lubricant", the poor snail comes to a standstill. This sheep's wool fleece takes advantage of the snails' vulnerability by simply slowing them down: the lubricant quickly seeps into the fleece, and the snail can't make any more headway. The fleece becomes an effective and benign mechanical snail barrier.
