RESPONSE
At the Coconut Rhinoceros Beetle (CRB) Response, our mission is to protect Hawai'i's communities, industries, and natural environment from the threats and impacts of CRB. Our mission is achieved through education, awareness, detection, prevention, and treatment, with the help of our partners and the public.
Coconut rhinoceros beetles (CRB) or Oryctes rhinoceros, native to Southeast Asia, are a threat to palm species outside of their native range. Adults are about 2" in size, and larvae grow to 3.5 - 4" before pupating.
If you are on O'ahu you do not have to report CRB. On all other islands, please report any coconut rhinoceros beetles, larvae or tree damage. For more guidance on what to report or to submit a report follow the link to our reporting page.
We recommend implementing best management practices, and exploring treatment options for controlling CRB populations.
CURRENT STATUS
Coconut rhinoceros beetles (CRB) have not spread to all parts of Hawai'i. Their range in the Hawai'ian Islands is currently limited to O'ahu, certain parts of Kaua'i, and recently found on Maui and Hawai'i Island. You can help prevent accidental transport of CRB in Hawai'i by limiting the movement of infested breeding material.
