Throw away food boxes and packages
Yes, that includes boxes where you see no bugs. The female beetle deposits eggs into food or into crevices in food packages. The larvae hatch and make their way into the product to eat. Unless you've inspected every corner and crevice of each box with a magnifying glass, you have no way of knowing

Choose an ORGANIC pest control spray with residual effects
It's not wise to spray chemicals where food is stored! Choose an organic product for use in kitchens. Some organic products simply kill on contact. Once the spray dries, there's nothing left behind to discourage pests hiding behind walls from wandering back into sprayed territory. Dr. Ben's Evictor kills on contact and leaves behind a powerful cedar aroma that discourages pests from entering sprayed territory.
How to poison weevils behind walls
No matter what type of spray you use, pests hiding behind walls won't be reached. While some weevil infestations are just connected to packages, advanced or chronic infestations can involve critters hiding behind walls. To battle this problem, mix equal parts boric acid with flour. Fill a small bowl with the mixture and place it on the floor inside your infested pantry. Stray weevils emerging from walls to find food will eat the bait and die.
Traps can also help
Fill a small cola cap with flour. Stick the cap inside of a glue trap. Adults searching for food will crawl inside and get stuck on the glue.
