Don't throw all that food away!
Put the jars in the freezer overnight to kill the blighters, then pour them out on a nice clean table top and sort them out, as we used to do with the rice.
OK, we did rinse the rice in cold water before we cooked it, but the odd ingested weevil ain't going to hurt a couple of tough old persons like you, is it?
EDIT.-If we'd thrown away the rice because it had weevils, stones, and mouse crap in it when we lived in Sarawak, we'd not have had much to eat, and if we were bothered about little things like that, we couldn't have eaten in any local places.
Potatoes were really expensive, as they were only flown down by light aircraft from the mountains, or very old imported ones from far away.
On some great and glorious day the plain folks of the land will reach their heart's desire at last, and the White House will be adorned by a downright moron.
