Sometimes these heetles come out in the fall, hut in most cases they stay inside the peas until spring. They do great damage to the peas by destroying the germ.

I'he bins are shut tight and the beetles are killed by the fumes. If the peas are kept o\er until two \-ears old the beetles will mature and die in the bins the fust Near, and the seed then sown the second )ear will be entirely free from the pest.
