You must remove all animals and people prior to applying
FastOut Foam or any other insecticide. People and animals can return as soon as the area that was treated is dry. According to the product label "Make spot, void and/or Crack & Crevice treatment to localized areas including shelves, cupboards and storage areas where food
products suspected of being infested are located. Remove or cover food before treatment. This treatment is supplemental to good housekeeping, since it will have no effect on insects within packaging. Infested food packaging should be destroyed".
