Xylophagous insects, a factor not to be overlooked!

Sometimes your trees show symptoms like many holes, leading to galleries inside the trunks or large branches, called carpenters. They are often caused by the implantation of capricorn larvae (fig. 1) or bark beetles which are xylophagous insects.
Some insects such as the xylocope called carpenter bee (fig. 2) dig the wood in order to nest.
These insects therefore affect the structure and the solidity of the trees making them more fragile and therefore more easily subject to breaks by carpenters or sometimes by the whole tree.
Do not take lightly the abundant presence of wood-eating insects on your trees!
