Currently spending some time in Cuba and recently salvaged a couple of mahogany logs (
trees being cut down for road works). The logs were debarked and left on a covered patio to dry while I decided what I would build with
wood.
I recently noticed that something is boring into the log. The diameter of the hole is about 1mm, I probed the holes with a wire and they extend in about 1 to 2 cm, not sure if the path of the hole then has a turn or not. I have been unable to see any of the boring insects. I am not sure if it is an entrance or exit hole? See photos.
Based on what I was able to quickly find on the internet, it is not termites as they do not produce sawdust/frass, but is more likely some sort of boring beetle?
I would like to identify what the insect is and figure out the best non-toxic treatment to eradicate this pest.
