Saw-toothed or merchant grain beetle

5916   Please help me! I need an idea of what these bugs could be. I really need to know how to get these out of my home it has been going on for over 3 years at this point. I have tried every insecticide available, steam and freezing cold and there are always more.

This is a grain beetle (Coleoptera: Silvanidae) in the genus Oryzaephilus, either a saw-toothed (O. surinamensis) or merchant (O. mercator) grain beetle. Both species are cosmopolitan pests of dry stored food products, including dry pet food. You need to conduct a thorough examination of all food storage areas in your home to find the source(s) of the infestation. See http://tinyurl.com/jnc6w7k for some control/management suggestions.
