This snail trap set keeps snails and slugs away from your crops and flowers! To prevent snail nuisance, it is important to start snail control early in the spring. You can use these snail traps in two ways. The non-toxic and environmentally friendly way: beer, where the smell of yeast attracts the snails and the snails fall into the beer and drown, or fill the trap with snail pellets which stay dry longer in the snail trap and are out of reach of other animals. ( Please note, both ingredients are not included.)This slug trap works best when placed near flower or plant beds, as this is where slugs are most commonly found.
