Overview of Flathead Borers
Flathead borers pose a significant threat to stone fruit trees, particularly peaches and plums. These pests typically attack the trunks and larger branches of trees, causing extensive damage. Their larvae tunnel into the wood, creating galleries that weaken the tree structure and lead to dieback or, in severe cases, tree death.
Signs of Infestation
Identifying flathead borer infestations early is crucial. Signs include:
- Bore Holes: Look for small, oval-shaped holes in the bark, often one-eighth to one-quarter inch wide.
- Mature Beetles: Spot adult flathead borers during late spring and early summer. They are dark brown to black with distinctive flat heads.
- Wood Dust: Find frass, or sawdust-like material, at the base of the tree.
- Declining Health: Watch for wilting leaves, stunted growth, and dieback, indicating internal damage.
Affected Tree Areas
Flathead borers typically attack specific areas of stone fruit trees:
- Trunk: Look for primary infestations here, especially in injured or stressed trees.

Common Stone Fruit Trees Affected
Flathead borers affect a variety of stone fruit trees. Understanding which trees are most susceptible helps you take preventive measures.
Peach Trees
Peach trees are frequently targeted by flathead borers. This pest typically attacks the trunk and major branches, weakening the structure over time. Look for signs such as small holes in the bark or wood dust at the tree’s base. Healthy peach trees are less likely to face infestations, so maintain proper watering and nutrition.
Plum Trees
Plum trees also experience significant damage from flathead borers. The larvae might tunnel into the wood, causing dieback in affected areas. Inspect the trunk and branch junctions regularly. Noticing premature leaf drop or discoloration may indicate an infestation. Prompt action, such as pruning affected limbs, can help preserve the tree’s health.
Cherry Trees
Cherry trees are not immune to flathead borers. These pests typically invade the crotch areas and larger branches, halting growth and reducing fruit production. Monitor your cherry trees for bore holes or drooping branches. If an infestation occurs, consider applying insecticides or using trap trees in your yard to lure pests away from main trees.
Symptoms of Infestation
Identifying signs of flathead borer infestation is key to protecting your stone fruit trees. Look for these specific symptoms to assess tree health.
Entry Holes and Bore Dust
Small entry holes often appear on the trunks and branches of infested trees. These holes indicate where adult beetles have entered. You might also notice sawdust-like bore dust accumulating at the base of the tree. This dust, created by larvae tunneling through the wood, signals infestation. Regularly inspect your trees for these signs. Early detection is essential for effective management.
Wilted Leaves and Branch Death
You may observe wilting leaves as a significant sign of health decline in your stone fruit trees. Infested trees often exhibit drooping foliage and dying branches. These symptoms occur due to the damage caused by larvae feeding within the wood. If multiple branches show signs of death or dieback, the tree may be severely affected. Address these issues promptly to minimize further damage and increase the chances of recovery.
Geographic Distribution
Flathead borers’ geographic distribution primarily spans regions with warm climates, where stone fruit trees thrive. Understanding where these pests typically attack helps you protect your trees effectively.
Regions Most Affected
Flathead borers inhabit various areas across North America. Key regions include:
