People and pets need to be out of the area while you make an application with Bonide Dual Action Bed Bug Killer RTU and stay out of the treatment area until it is dry. Once the treated area is completely dry, then, it is safe to resume normal activity. How long this will take will depend on how much of the product is sprayed as well as a few other environmental factors. Generally, it takes anywhere between 1-4 hours to dry completely. Please be sure to review the product label for more information and complete application instructions.
