There is a wide spectrum of pathogens that stress and kill trees. Depending on which insect, fungi or virus may be affecting your tree, there are several courses of action that may be advisable. Knowing which pathogen it is can potentially save you money or reduce the risk to your family, home, or neighboring trees. A beetle infestation in an old pine may necessitate that tree's removal before it is entirely dead. The declining tree can act as a breeding ground for the beetles, who then emerge and attack neighboring trees. These are known as "brood trees". Alternatively, it may just be oak gall wasp, which is normal and benign but can sometime look menacing.
