Weevils and meal worms/moths.

I’ve wandered into the kitchen to found a swarm of tiny moths fluttering around, before.

A search turned up a box of sealed and airtight dark chocolate brownie mix with an entire civilization thriving inside.

All dry goods have some kind of bug eggs in them.

Freezing the stuff *might* extend the shelf life.

Spot on. The food preservations I talk to say there are one of two ways to prevent this problem:

1. Heat treatment-- 200 degrees F. or greater for two hours or more.

2. Freeze treatment of 0 degrees F. or less for two days or more.

   The freeze treatment is FAR trickier because most dry goods have better cold insulation than heat insulation properties.

I rebag my bulk dry goods into brown paper lunch bags inside of gallon freezer bags and give them a several week trip through the 0C deep freeze.

Have had no issues wrt bugs since I started that.

YMMV.
