The problem is if there is no pathway for gas to penetrate the product then beetle will be still alive ( product which contact directly with gas , turned to be toxic )

Immunity could be one of reasons , check this link http://legacy.crcpla...n-beetles.html 

I think you have to change type of fumigation gas.
