Pine Beetles in Eastern North Carolina: Signs Your Pine Is in Trouble
Loblolly pines are everywhere in Craven and Pamlico counties, and so are the beetles that kill them. Here is how to spot an attack early, and how to tell it apart from normal needle drop.
By Pamlico Tree Care · Grantsboro, NC · October 2026
The short answer
The signs of pine bark beetles are small blobs of sap called pitch tubes on the trunk, reddish boring dust in the bark crevices or at the base, and needles that fade from green to yellow to red. Under loose bark you may find winding tunnels. Three beetles cause most of the damage in North Carolina: the southern pine beetle, Ips engraver beetles and the black turpentine beetle. All three go after pines that are already stressed.
4 signs a pine is under attack
Bark beetles are tiny, about the size of a grain of rice or smaller, so you will almost never see the beetle. You see what it leaves behind.
Pitch tubes on the trunk
When a beetle bores in, the tree pushes out sap to try to flush it. The sap hardens into a small, crusty blob around the hole, often described as popcorn sized. The N.C. Forest Service notes that on southern pine beetle attacks, these can be high up the trunk, so a pair of binoculars helps.
A badly stressed tree may not produce pitch tubes at all, because it does not have the sap to fight back. No pitch tubes does not always mean no beetles.
Reddish dust
Fine reddish brown boring dust collects in the bark crevices and around the base of the tree. It looks like sawdust and is easy to miss on pine straw.
A fading crown
NC State Extension describes the color change as green to light green, then yellow, then red. On a tree hit by the southern pine beetle or black turpentine beetle the whole crown changes. With Ips beetles it may only be the top or a few branches at first. Often the first thing people notice is a red-topped pine.
Tunnels under the bark
Where bark is loose, peel back a piece. Winding tunnels etched into the wood, or into the inside of the bark, mean beetles have been feeding. The shape helps identify which beetle it is.
The three beetles that kill pines here
- Southern pine beetle. About 1/8 inch long, and described by NC State Extension as the worst pest of southern forests. Its tunnels are S-shaped and wander across the grain of the wood. It tends to kill pines in spots, several trees next to each other, and the spot can grow outward.
- Ips engraver beetles. Three species in North Carolina. Their tunnels are shaped like an I, Y, X or H and run with the grain. They usually hit scattered single trees, often after drought, storm damage or a lightning strike, and may start at the top of the tree.
- Black turpentine beetle. The largest of the three at about 3/8 inch. It leaves large pitch tubes on the lower 15 feet of the trunk and favors trees that have been recently wounded.
Did you know?
Pines lose some needles every fall, and that is normal. Healthy needle drop is yellow and brown on the inside of the branches, evenly through the tree, with green tips. Beetle damage shows up at the tips or from the top of the crown down. Our fall tree care checklist shows how to tell them apart.
What sets off an attack
NC State Extension notes that most pine bark beetles go after trees already weakened by something else. The usual triggers in eastern North Carolina yards:
- Drought, especially a dry late summer
- Storm damage, broken tops and twisted trunks after a hurricane
- Lightning strikes, which often show as a spiral strip of missing bark
- Wounds to the trunk from mowers, trucks or equipment
- Root damage from trenching, grading or a new driveway
- Crowding, pines growing too close together and competing for water
That is why beetle problems often show up a season or two after a big storm or a dry year, and why one stressed pine can turn into several.
What to do if you find them
- Look at the neighbors. Check the pines around the affected one. Southern pine beetle in particular spreads from tree to tree.
- Get it confirmed. The N.C. Forest Service has county rangers who can help confirm whether you are looking at southern pine beetle.
- Know when a tree is gone. NC State Extension notes that lightly attacked trees may survive, but a pine whose whole crown has turned red is dead. For southern pine beetle, the recommended response is to remove infested trees promptly, along with a buffer of nearby trees, to stop the spread.
- Do not leave a dead pine standing near the house. Dead pines dry out and weaken, and they become harder and riskier to take down the longer they stand. See our tree removal page for how that work is done.
How to protect the pines you have
- Water large pines during long dry spells, slowly and deeply, out at the edge of the branches.
- Keep mowers and string trimmers off the trunk. A mulch ring around the base helps.
- Keep trenching, grading and heavy equipment off the root zone.
- Cut live pine limbs in the cooler months. Our guide to the best time to trim trees explains why.
- Thin crowded pines. NC State Extension calls thinning the best way to prevent an outbreak in a stand of pines.
- After a storm, have broken and damaged pines dealt with before they draw beetles to the healthy ones.
Common questions
What are the signs of pine beetles?expand_more
Look for small crusty blobs of sap called pitch tubes on the trunk, reddish brown boring dust in the bark crevices or at the base, and needles fading from green to light green, yellow and then red. Winding tunnels under loose bark confirm beetles have been feeding.
Can a pine tree with beetles be saved?expand_more
Lightly attacked pines may survive if the stress that weakened them ends. A pine whose whole crown has turned red is dead and will not recover. Infested trees attacked by southern pine beetle should be removed promptly to protect nearby pines.
What attracts pine beetles to a tree?expand_more
Stress. Most pine bark beetles attack trees already weakened by drought, storm damage, lightning, trunk wounds, root damage or crowding. The black turpentine beetle especially favors recently wounded trees.
Is it normal for pine needles to turn brown in the fall?expand_more
Yes, if it is the older needles on the inside of the branches, spread evenly through the tree, with green tips. Browning at the branch tips, from the top of the crown down, or on one pine while its neighbors look fine points to beetles or root trouble.
Who can confirm pine beetles in North Carolina?expand_more
The N.C. Forest Service has county rangers who can help confirm a southern pine beetle infestation. Your county Cooperative Extension office can also help identify the problem.
Got a pine that does not look right?
We have worked across Craven and Pamlico counties since 2000, from Grantsboro, and we take down a lot of pines. Jon looks at the tree himself before anyone quotes a number, and he will tell you whether it is beetles, normal needle drop or something else.
If you already know what you need, start with trimming and pruning, tree removal or stump grinding. More guides are on our blog.
