Adult burnt pine beetle females are 12-30 mm long. Males tend to be smaller than females.
Females are dark brown to black, while males are usually a lighter brown. The body is elongate and oval in cross section, as in most other longhorn beetles. The thread-like antennae are more than half the length of the body.

Adults live for several weeks and may be present between November and March.

Note: The Two Toothed Longhorn borer beetle looks similar but can be a threat to timber buildings.


  • Burnt Pine Beetles are not normally a pest except as a nuisance when large numbers fly or crawl indoors. Numbers can be reduced by spraying the exterior of a building and any stored firewood with NO Bugs Super.
