I Must Garden All Natural Dog & Cat Repellent is not waterproof, meaning it will not hold up forever through rain and weathering. However, it does have some residual so you should apply it when it is not going to rain for a day or two to have optimum time to dry and stick. After which, it will last through some rain events, but typically this product is only good for a couple of weeks. If you have a heavy rain or it is applied in an area with constant irrigation or sprinklers every day, it will not last very long.
