I read a building and pest report and it had Wood Borer damage, apparently the damage was on some timbers under the building on the ground (not the building) the building report comments below. "found Damage found Yes - Borer damage was noted to the following timber(s)/area(s). Without destruction of the timbers it is not possible to determine whether activity exists or the extent of timber damage within. Description Queensland pine beetle/ borer (Calymmaderus Incisus) damage" has anyone experienced this before? how bad are they?
