Signs of Pine Beetle Damage in South Alabama

Early Signs on the Trunk

• Pitch tubes: small blobs of sap, often white, yellow or reddish, where the tree tried to push beetles out of the bark.
• Boring dust: fine reddish-brown sawdust in bark crevices or around the base of the trunk.
• Small holes in the bark, about the size of a pencil lead or BB.
• Woodpecker activity that strips patches of bark while the birds feed on the larvae.

Black turpentine beetles tend to attack the lower few feet of the trunk and leave large pitch tubes. Ips beetles often start near the top or in large branches.

Signs in the Canopy

As beetles cut off the flow of water and nutrients, the needles change color, usually from green to yellow, then to reddish brown. By the time the whole crown has turned, the tree is typically dead, even if some needles are still hanging on.

Under the Bark

If loose bark is peeled back, beetle galleries appear as winding channels etched into the wood. Southern pine beetles leave S-shaped galleries, while Ips beetles leave Y- or H-shaped patterns. Blue staining in the wood is common after an attack.

What to Do If You See These Signs

A pine with fresh pitch tubes all around the trunk and fading needles usually cannot be saved. Removing it promptly lowers the risk of beetles moving into healthy pines nearby and prevents a dead, brittle tree from falling later.

If only a few pitch tubes are present and the canopy is still green, the tree may be fighting off the attack. A tree health diagnostic can help determine whether to monitor it or remove it.

Why Dead Pines Are a Safety Risk

Beetle-killed pines dry out and weaken quickly, and they can snap or drop large limbs without warning, especially in wind. A dead pine near a house, driveway or play area should be handled through professional tree removal rather than left to fall.

Keeping Healthy Pines Healthy

• Avoid damaging roots with vehicles, trenching or grade changes.
• Water during long dry spells when practical.
• Remove lightning-struck or storm-damaged pines promptly, since they attract beetles.
• Have dead and damaged limbs removed with proper tree trimming and pruning.

Other Reasons a Pine Turns Brown

Not every brown pine has beetles. Drought stress, root damage from construction, lightning strikes and root diseases can all cause needles to yellow and drop. Lightning often leaves a long strip of missing bark or a spiral scar down the trunk. Normal seasonal needle drop in the fall affects only the older inner needles, while the tips stay green. Looking for pitch tubes, boring dust and galleries is the best way to tell beetle damage apart from these other causes.

Watch Your Pines After Storms and Construction

Beetles are drawn to injured and stressed pines, so problems often show up weeks or months after a hurricane, a lightning strike or heavy equipment working near the trees. If you have had a storm, a new driveway or foundation work near your pines, check the trunks for pitch tubes over the following season. Catching one infested tree early can protect the rest of the stand.

Have Your Pines Inspected

If you are seeing pitch tubes, boring dust or browning needles, call Dothan Tree Service. We will look at the tree, tell you what we find and give you a written estimate if it needs to come down.
