Weevils aka mjölbagare in Swedish.

Weevils also known as mjölbagare in Swedish.

Flours, grains, even rice are accompanied by tiny little eggs that, with the right conditions, will hatch into larvae. Left long enough they will turn into full blown beetle backed creatures with legs and antennae. Sometimes you see it right away, sometimes you don’t notice until your pie crust starts to crawl away motored by squirming little worms. Yikes!

The solution is very, very simple. Freeze the eggs to death. I put all newly bought packages of flour, grains, and rice in the freezer over night. It kills the eggs without harming your product. Problem solved.
