Frequently Asked Questions
Q: Why is CRB a problem?
Coconut rhinoceros beetles feed on palms and other tropical plants, damaging their fronds and killing the tree in severe cases. The average economic value of a single palm tree on Oahu is $3,000, in addition to its cultural and ecological value, and there are tens of thousands of palms on-island.
Q: Where are beetles being found?
A: Most of the beetles are found in Pearl City Peninsula South of H1, and the Waipio Peninsula. There are significant populations in Ewa Beach, Iroquois Point, Waipahu, Waikele, Mililani Agricultural Park, and agricultural lots in Kunia.
Q: What should I do if I find a beetle/larva?
A: Capture it alive if you can (dead is OK) and put it in a hard plastic or glass jar that is well-ventilated. Note where you found it, take photos and notify the CRB Response immediately at 679-5244 or BeetleBustersHI@gmail.com. We will schedule a time with you to pick it up.
Managing green waste and palms
Our best management practices were developed to ensure your yard, farm, or business does not become a CRB breeding site or vector for beetle spread. The CRB Response is happy to work to find a solution for your needs.
Always report tree damage, coconut rhinoceros beetle larvae or adults, or potential breeding sites to the CRB Response team. Contact us to discuss treatment options specific to your needs and location, and we can help assess your risk.
2. Know your Zone
Coconut rhinoceros beetle populations have not spread across Oahu or to neighbor islands, but transporting green waste or palms from infested areas to uninfested areas is a likely pathway for spread. Minimize the movement of green waste, and contact us for free inspections of materials before they are moved.
3. Contact Us
The CRB Response is available for a free site survey and inspection if you are concerned about mulch on-site. We are also happy to provide recommendations about hot composting that heats mulch piles over 140 degrees F.
