Insect Pest Prevention and Management

Invasive pest species are easily spread by people moving themselves, their pets, and things they use as they travel from place to place. These pests pose a threat to our natural ecosystems, recreational activities, agricultural crops, and even human health. You can help the spread of invasive pests by following the guidelines below.


Trees are being destroyed through the transportation of invasive insects and diseases found in firewood. Do not move firewood, but instead obtain it from local sources. Burn firewood in the same general area as the wood source. As a general rule, 50 miles is too far and 10 miles or less is the best.

Prevention of infection

  • Contact the Oregon Department of Agriculture (ODA) for a free inspection of outdoor household goods and recreational vehicles if you have recently moved from a northeastern state.
  • Grant ODA seasonal survey staff permission to place traps on your property during the summer.
  • Look for and report to ODA any suspected egg masses and pupae which can travel to the US from Europe, Russia, China, and other infested areas.
  • Check with ODA before importing plant material or ordering it online to determine if the material is quarantined or could potentially harbor invasive pests.
  • Inspect your vehicle before a long trip and after arriving at your destination.
  • Report an invasive pest using the online insect identification and report form​.


Buy It Where You Burn It

Be aware that firewood can harbor insects and diseases that threaten Oregon's valuable forest resources. Transporting firewood can move these pests to new locations. Website
