A couple of nights ago we were kept awake by a loud and intermittent clicking sound, and I do mean loud, akin to a noisy clock. We were eventually able to narrow down the source of the noise to a wooden chair, one of its legs to be more precise.
In the morning upon closer examination of the noisy leg, there was evidence of little piles of dust on the floor around it. I took a screwdriver to the timber and began scraping away the loose surface, I didn't stop until I had uncovered three of these quite overfed larvae which had completely annihilated the chair leg.
I've removed the chair from the house in case there are any more in it. Should I be concerned that they have already infested other parts of the building?!
