They never attack corn and wheat.

The crop should he harvested as soon as possible after maturity and the seeds thrashed or shelled and treated by fumigation, heat, or cold storage, in order to kill the weevils in them before they can continue their destructive work and mature.

The bean and cowpea weevils breed generation after generation in stored seeds. Hence seeds should be watched after treatment to make certain that they do not become reinfested. If stored in tight containers or in rooms free from adult weevils the chance of reinfestation will he reduced to a minimum.
