Roundheaded Borers (Excluding Asian Longhorn Beetles)

Cerambycidae family

Wood-boring larvae of longhorned beetles (Cerambycidae family) that tunnel through trees. Adults are called longhorned beetles due to their long antennae. These pests primarily attack damaged, dying, or recently-killed trees where they lay eggs on bark.

Identification & Symptoms

What to Look For

Holes in bark with round exit holes
Stains or oozing liquid on limbs or trunks
Piles of coarse sawdust around tree base
Foliage discoloration and wilting
Limb dieback
Tunnels packed with sawdust under bark

Potential Damage

Tunneling through wood weakens tree structure
Branch and limb mortality
Complete plant death in severe cases
Reduced timber value from tunneling damage

Lifecycle

Adults lay eggs in bark crevices of green wood. Larvae bore beneath bark and into wood, spending 1-3 years tunneling. Life cycle varies by species and season from 3-4 months in spring/summer to 9 months in fall/winter.
