These discreet pest strips effectively trap fungus gnats and other flying pests. Made from compostable corn instead of plastic, they are an eco-friendly alternative that can be disposed of in compost after use. Designed for versatility, they can be attached to the inside rim of a pot using their adhesive backing or placed in the soil with the included small stake. Each pack contains 20 pest strips, which should be replaced monthly or as needed for optimal results.
