Shiny spider beetles are pests that infest stored food products. These beetles can spread from one package to another when homeowners fail to store dry foods in airtight jars. These pests lay their eggs in almost all food products, especially if they are moist or moldy.
People often buy tainted goods from stores without realizing infestations. Shoppers may be able to spot evidence of moistness and the beetles themselves in highly infested packages.
