application of pure kerosene, benzine, or gasoline. Also, 

 where conditions are such that the infested wood can be 

 steamed thoroughly, this treatment will suffice to destroy 

 the pests. Again, if the wood can be subjected to dry 

 heat of sufficient degree for several hours, the pest will be 

 killed. It has been demonstrated that certain mill insects 

 may be killed if subjected to a heat of 125 to 130 degrees 

 sustained for several hours or long enough to give it time 

 to penetrate evenly all parts of the infested portion. 



In case of the other beetles mentioned, the same methods 

 of control will hold for them as for the drug-store beetle 

 and the grain beetles already discussed.
