A weevil is a small beetle-like insect that often damages stored grain. There are several types of weevils and they are usually destructive and have a short lifespan.
Positive: To dream of a weevil may represent destructive character traits or anxieties in your life that God is giving you a chance to change. God could be trying to warn you of the enemy before he comes.
Negative: Dreaming of a weevil could also symbolize deception and losses that have happened or are going to happen in your life. Weevils are destructive and God could be showing you there is something in your life that is destroying your harvest.
(Genesis 8:22; John 10:10; Joel 2:25).
