Question: There is a bag of sugar that is full of **dead** weevils. These tiny insects are just the same size as sugar particles. If they were alive, I could expose them to the sun and they would fly away. If their size were different than the sugar particles size, I could filter them through a mesh. Any practical suggestions to get rid of these dead insects and save the sugar?

Answer: 
You can dissolve the sugar in water and filter it, then evaporate the water.
how much money are you talking about? Dead Weevils (yuk!) I'd toss the whole bag and buy another rather than swallowing dead weevils. Not my kind of protein.
