Default Termites Attacking Trees

Live in Raleigh NC. Have a running contract with a pest control company that does the quarterly inspections for termites and other pest in and around the exterior of the home. No issues in the home at all. We own about 2 acres 75% wooded (80% pines). Noticed a couple dead pines behind the house over the last 4-5 weeks, but they are basically in the woods as we back up to the woods. Wasn't really all that concerned as trees die. Noticed the other day a new dead tree inside the fenced in portion our back yard, pulled a piece of bark away and saw termites. I have now noticed 5-6 trees around the property that are looking the same. It appears we are in a full scale attack from termites. Currently they are only attacking pine tress. Thoughts from the resident experts? If I could go under contract with the head termite and strike a deal where they only took out 50% of my pines so my hard woods could actually grow I'd let them stay, unfortunately I don't think they will follow the rules we establish. Called exterminator we use now and they said they only treat homes, not trees in the yard.

Or, something else is killing the trees and the termites are just taking advantage of the free meals. If you leave any piece of wood or even cardboard out in the yard long enough - you will see termites.

Those look a lot like pine beetles.

So we do a pretty good job of trying to make sure any dead limbs that fall are removed pretty quick. We don't leave any wood outside, not even fire wood. I have a couple things I have built for the kids, a wooden swings set and a tree house, neither of which seem to be bothered.

I think pine beetles are black, and termites are white.

In Arizona I use Bifen I/T , we had termites on our Pine trees.
Amazon has a great price, local wanted twice the $ .
Easy to mix, pump up sprayer.

Termites usually come after the fact. Wood bores or pine beetles kill it first then the termites move in,
MOTHER of all termite mothers??

Yep, I'm up to speed on how nature works, just looking for a recommendation to keep the rest of my property from being destroyed.

Still very much think they are pine beetles. Just based on seeing them lots of times. Get a few and take them to NCSU's local extension office. They will likely send it off to the Entomology lab for confirmation.

No way an exterminator can keep bugs away from outdoor plants; its the nature of.......well, nature. Removing affected trees is the only answer. You need to keep an eye on the tops of all pines and remove affected tree and surrounding trees for good measure. it's a mess.

I think those are termite larvae. Pine bark beetle larvae do not have a distinct head and body, they are more centipede-like. Bifenthrin is a good chemical but a termiticide such as Termidor (Fipronil) is more effective. Try a local arborist or horticultural spray company. Treating trees for termites is very common in my area.

What you are seeing is the result of the trees dying not the cause. Not enough information to determine cause of mortality. Perhaps lightning strike, mechanical injury, or some other stress factor.

The first thing you would see would be small pitch tubes and maybe a bunch of what looks like popcorn around the base of the tree. That would be the work of southern pine beetles and/or ipps beetles. At this stage, you can chop and pull away a section of bark and if the cambium channels are Y-shaped they are Ipps, if S-shaped they are southern pine. Larger pitch tubes if black turpentine beetles. This is the initial attack phase likely resulting from a stress factor. Then the ambrosia beetles come and you get the fine white sawdust around the base of the tree. Tree is dead at this point despite top still being green. Then you get the other wood borers and termites.

You can spray the first few feet of the tree stem from ground with lindane if you can get it, malathion, dursban, or offroad diesel. It would only do any good at the time of the very first attack by bark beetles when the pitch tubes first appear, and even then the most effective method is to remove infested trees as soon as possible when they show signs of beetle attack.

You can remove the dead trees if you are concerned about the termites, but it won't help with spread of beetles.

Those are subterranean termites, and pine is their number one food source.
