These pests have a well-earned reputation for being very persistent and difficult to eradicate. It is essential to inspect all stored food within the home and check it thoroughly for signs of infestation. If there is any doubt at all about a particular product, throw it out. Make sure the discarded goods are completely removed from the home so any remaining pests cannot escape and continue the infestation.
Once all infested food products have been discarded, the best way to prevent re-infestation is to thoroughly clean all affected storage area surfaces.
Following successful eradication, all foods, particularly grains, flour, cereals and sugar should be stored in sturdy containers with tight-fitting covers. In many instances it is possible for these pests to make their way into food that is stored in containers with plastic snap-on lids such as Tupperware.
