Larval development beneath the wood surface often continues. Also, surface treatments generally do not control infestations of deep boring beetles such as the oldhouse borer. Apply lindane as a water emulsion twice, the second time before the first application dries completely. These applications to the unfinished wood surfaces will allow some penetration into the wood. If warranted, finishes may have to be removed before treatment.
Fumigation is the most reliable and effective method of eliminating wood-boring beetles.
A toxic gas penetrates beneath the wood's surface to kill most of the development stages of the beetle. However, fumigation will not leave any residual chemical on the wood surface to prevent subsequent infestation. Because it is a costly, highly technical and hazardous process, fumigation must be left to pest control operators experienced in this technique.
