The Coconut Rhinoceros Beetle (Oryctes rhinoceros)

---

The Coconut Rhinoceros Beetle (Oryctes rhinoceros) is an invasive pest threatening the heart of our island — our palms. These beetles bore into the crown of the tree to feed, leaving V-shaped cuts, chewed fronds, and over time, can cause crown rot or even tree death if left untreated.

We see every palm as part of the island’s identity — worth protecting with care, precision, and respect for the ʻāina.

What to Look For

• V-shaped cuts or holes in new fronds
• Chewed or shredded bases near the crown
• Soft or hollow areas at the top of the trunk
• Frass (a sawdust-like residue) near the crown

If you spot these signs early, treatment can stop further damage and help your palm recover.

Our Treatment Method

We use systemic trunk injections, a precise and environmentally conscious approach. The solution is delivered directly into the tree’s vascular system, protecting it from the inside out — right where the beetles attack.

The treatment is sealed inside the tree, not sprayed into the air, meaning there’s no drift, no runoff, and minimal impact on people, pets, or pollinators. Just a healthier, stronger palm.

🌺 Our Promise

At Treevive Kaua‘i, our goal is simple — to protect Kaua‘i’s palms while keeping the island’s environment safe.

Every treatment is measured with the tree’s full life cycle in mind, ensuring long-term health without harm to the surrounding ʻāina.

We’re here to help you preserve paradise — one palm at a time.
