Hydrogen phosphide is not a good penetrator of wood for control of ppbs. If the items are small a freezing process, followed by a warming, then plunging the materials again into freezing will elimiinate active infestations in wood.
The first time do it at -20 degress F for 72 hours; then warm the object up to room temperature, then freeze 'em again for 3 days at -20 degress F. Your problem will be elimanated.

Hi,
My name is Katie Fisher and I’m the new Pest Control Technician at the Glenbow Museum. I just wanted to ask a somewhat out-there question regarding the detection of wood borers… this museum has been battling Powderpost Beetles for quite a while. Every 5 or so years a new wave will appear, a large-scale treatment process will happen (phosphene), but it just doesn’t seem to be effective in getting rid of the Powderpost population.
Since it takes years for them to exit the wood, I feel like I’m somewhat just twiddling my thumbs in the meantime, wondering if the last treatment did the trick. A friend suggested that I might be able to use a stethoscope to hear the larva inside the wood… does anyone do this, to detect woodborers? Does anyone think it would be at all effective in hearing them?
Cheers,
Katie
