Signs You Might Have A Bark Beetle Infestation
There are more than 600 different species of bark beetles and over 41.7 millions acres of land destroyed from them. They are becoming more common as time goes on and date back to 1996, when the first outbreak began in the U.S. Bark beetles usually go after the weaker trees, decayed or already taken over by some sort of fungus or bacteria. They kill the trees by cutting off their food and water transport abilities.
Symptoms of bark beetles include:
Pitch tubes, reddish brown in color on the outside of the bark
Sawdust substances around bark
Woodpecker holes could indicate there are bark beetles present
Leaves and needles turn from green to reddish brown
Tree decline
Unfortunately, once the symptoms of bark beetles are noticed, it usually is too late to apply a pesticide and the tree must be removed to prevent further spread in the area. If you notice the bark beetles early on in their cycle, a pesticide can be applied by a certified Arborist that kills the adults when they land on the tree. This will prevent them from entering, laying eggs and repeating the cycle.
When applying pesticides, make sure you use a certified arborist, as these chemicals can be dangerous and cause more harm to the good and helpful insects of the tree.
If you suspect bark beetles on your trees, it is important to contact your local ISA certified arborist immediately to remediate the situation before they take over.
