Hi I found a tiny white insect crawling around the dried sauce mix packets in my kitchen cupboards about the size of a pinhead, my cupboards are very dry and clean, ant ideas anbody, thanks

My first guess would be the larva of one of the small pantry beetles, recently hatched from some contaminated dry goods.

Did it look anything like this?

Remember that larva is less than 1/4 inch long (1-2mm)
