A non-toxic slug bait that's safe to use around pets, wildlife and even in vegetable gardens. The active ingredient is organic iron phosphate, a compound that breaks down into fertilizer so uneaten pellets actually nourish your plants. Scatter about 1 teaspoon per square yard in the evening where slugs and snails feed. Once they eat the pellets the slugs die in 3 to 6 days. Remains active up to 2 weeks.
