Lost Coast | Plant Therapy Plant Therapy 12 fl oz

Plant Therapy is a concentrate that controls insects on contact by suffocation and dehydration and also treats powdery mildew. It doesn't rely on a poison and doesn't leave a harmful residue on the plant, according to Lost Coast. The 12 fl oz bottle mixes with water to make 12 gallons of spray.

Lost Coast says it won't harm bees, ladybugs or praying mantises. It's Clean Green Certified for use on organic crops, and is labeled for houseplants, yards, gardens and commercial farms.

Tip: contact sprays only work on what they touch, so cover the undersides of leaves where pests sit.
