Spreading sticky trap material around the stalks of more mature plants is one way. Another method is to wrap pieces of burlap around the base of the plants. Weevils love to hide in the folds of burlap during the day, and can be shaken out to remove and identify them. Something else to try is shallow pans of water, as weevils seem to be attracted to them and will drown when they crawl in. Many types of control are available for infested plants.
Weevils sometimes enter homes, probably to overwinter.
