Sails in South Africa seemingly have an affinity for grapes, and in order to prevent infestations that can wreak havoc on vineyards, wine producers often rely on pesticides as a means to rid snails from their vineyards. Although this method may be a solution to the invasion, it can also damage the natural ecosystem in the vineyards.
In place of chemicals, we rely on native birds and insects to combat pests. Foraging ducks live off of pests like bugs and snails, and we are more than obliged to invite them into our vineyard rows to snack on any pests present. This system is both more effective and sustainable; the ducks are only interested in the snails, and the grapes and environment are left unspoiled by synthetic pesticides.
