Pine Sawyer Beetle Indoors: Firewood Hitchhiker

Large metallic beetles emerging indoors in San Diego mountains likely came from firewood. Pine sawyers breed in dead/dying pines; adults emerge from stored logs.

Prevention

1. Store firewood outdoors until burning.
2. Bring in only what you'll burn immediately.
3. Screen windows/doors; seal gaps.

Facts

• Don't bite, sting, or damage homes.
• Not a sign of infestation in live trees.
• One beetle = no population indoors.

No treatment needed. Just adjust firewood habits.
