Follow the direction on the label. Clean up, vacuum and even killed any large bugs. Sprayed bed an baseboards even around the floor. In 1 week had small ones back. Sprayed again will have to see what happens.
Excellent product. After using this product I haven't seen any bed bugs around my furniture or bed. My it is clean. This product is super easy to use. You only have to shake and pour into a sprayer. No mixing.
