Sudden Tree Death: Need Species ID to Diagnose

Brown Leaves, No Green Under Bark, Big Ants

Without knowing the tree species (Bradford pear + unknown), diagnosis is impossible. Pests/diseases are host-specific.

Next Steps

• Attach close-up photos of leaves, bark, and ants to your question.
• Or email to expert with "Allexpert question" in subject.
• Scratch bark on twigs: green = alive, brown = dead.

Carpenter ants nest in dead wood—they're a symptom, not the cause.
