^H species and live in granaries, storehouses, barns, 



etc. Their larvae are the "meal-worms" which

grain remnants or debris. By removing or 

 changing such refuse their breeding places will be broken up and 

 the beetles kept in check. When its use is practical carbon bi- 

 sulphide will kill both larvge and adults.
