Shake well before use. For best results, spray insects directly. For general insect control, spray problem areas such as baseboards, entryways, storage areas, and dark corners. Spray until the surface is covered and repeat the process twice per week. Though the ingredients are mild and will not damage most surfaces, test before applying broadly. Mighty Mint Home & Patio Insect Control works for several insect varieties, including spiders, roaches, flies, and ants.
