Re: [pestlist] detecting woodborers
Katie - PPB's usually go through a one or two-year life cycle, depending on the species. They leave small, round exit holes. They are not like some of the structural, long-horned beetles, which may take up to 10-13 years to emerge as adults. These beetles leave large, usually oval exit or flight holes.Some have used portable x-ray units to find them in furniture. Injection of the exit or flight holeswith a pesticide is not a logical approach for the beetles have already emerged. In my career working with museums and conservators, most furniture and objects can be successfully frozen without harm to the piece. One should not freeze inlaid or parquet pieces, because of the dimensional problems previously mentioned. Tom Parker -Original Message- From: Hugh P.

Amplified, digitized, and recorded sound of their activity has been described in a recent WAG paper by a French person, and not yet online/published. Listening can help monitor, but not solve the problem. Is your issue with wood beams (structural) or decorative material? Hugh Glover.

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 Katie Fisher Pest Control Technician Glenbow Museum 130-9th Avenue S.E.

Re: [pestlist] detecting woodborers
Hi Katie I've used it - but don't recommend it because it only works if the larvae are actively feeding - otherwise they could be present, but you would hear nothing.
