These items should also be thrown out or disinfected by freezing or heating. Cleaning the area where the infested products were found is advisable, as well. Cleaning with bleach or ammonia, however, will not help with the eradication of the pests. Using a vacuum cleaner to clean the area thoroughly, especially in cracks and corners where insects may hide, will decrease the chances of reinfestation. Because food will be stored in that area again, pesticides are not a good method of eradication. Pesticides can leave a residue that can contaminate food products stored near it. Also, once a pest is inside the container, the pesticides have no effect. If the infestation is so severe that pesticides are the only way to contain the problem, a professional should be contacted immediately. Do not try to apply pesticides to any area where food is stored for human or animal consumption. Contamination can occur and cause illness or more severe conditions. Proper storage and cleanliness are the only ways to prevent an infestation from occurring. Sanitation is the key to prevention and eradication of any pests. If these insects are found infesting stored products, it is not practical to automatically assume the store or producer is at fault. Although some infestations are not the consumer's fault, producers are held by the FDA action defect levels to ensure their product does not contain more than the allotted amount of insects, insect fragments, or larvae. If a stored product is found to be infested by insects, and it is suspected that someone other than the consumer is at fault, a forensic entomologist can be contacted to make a determination. Again, it should not be assumed that these are the only five insects found in a common household pantry, but due to the large number of infestations by these five major groups, it can be safely deduced that it is perhaps one of these five. Stored product entomology is an important forensic field that is important to not only the government and the FDA but the general public, as it is involved in the consumption of food in everyday life.
