Repel Away gel crystals (1 pint) is a different/unique kind of outdoor repellent. Absorbed by polymer crystals the repellent provides continuous action by slowly releasing a strong highly perfumed odor confusing both dogs and cats senses of smell. The crystals are effective in most weather conditions. In dry weather the moisture of the crystals is drawn into the soil. Rain may occasionally cause the crystals to grow. The repellent remains effective either way. Size 14.5 oz
