Wow, that beetle looks amazingly a lot like these little beetles that my parents had a problem with proliferating in their cereals. They were very persistent and would do crazy things like chew neat little holes right through aluminized plastic pouches! Similar to the cigar treatment, freezing does kill them (they threw out the infested food though).
Not to hijack this thread, but I've been having a persistent problem with what I don't think are beetles... unless they are *extremely* young beetles, and it's related to the topic of freezing. I have a little box of Davidoff cigarillos that I noticed had very tiny white bugs crawling in it one day. Not very many, just a few in one corner over a couple of the sticks. This followed a problem I had with over-humidifying them temporarily. I froze the box for almost a week, and now a few weeks later I find them again.
Both times I checked to see if they had spread outside that box to anywhere else, and they hadn't. For lack of a better idea I put the box back in the freezer a few days ago, where it is right now.
I might do a few freeze/thaw cycles and see if that kills them, but does anyone know what these critters are and how to kill them? They are almost microscopic in size, like little white/cream coloured grains of fine sand or salt that move. I can't even make out what shape they are, they're so small, and I haven't seen any larger ones or even holes in the cigars.
Does wiping it down with alcohol (like cheap vodka) kill insect eggs?
