Stop Garden Crystals are for outdoor use to stop dogs and cats urinating or going near plants, fences, gates, letter boxes, bins etc.
HOW TO USE: Scatter repellent crystals on lawns, flower beds and around plants, shrubs etc. Repeat application every 3 to 4 days or as often as necessary, until undesirable habits have been broken. After a short time the animal will associate the treated area with something unpleasant and will avoid that area.
CAUTION: Do not use on edible crops
