How to Control Coconut Rhinoceros Beetle with quarterly beetlejuice yard spray

The Beetlejuice Spray is a naturally occurring fungus and one of Hawaii’s most effective biological tools for controlling Coconut Rhinoceros Beetle (CRB). Used in organic gardening, agriculture, and landscaping, It targets CRB but does not harm people, pets, or beneficial wildlife.​

Why Use a Quarterly yard Beetlejuice spray ?

The Beetlejuice fungus spray is a natural enemy of CRB, keeping beetle numbers balanced in healthy soil. Modern landscaping and mulch use to have reduced natural populations of this fungus—so reintroducing it is key to biological control. Hawaii studies show that it kills both CRB larvae and adults in 3–10 days after exposure.​

Where to Apply the Beetle juice spray

Most CRB spend their lives breeding in mulch, compost, and decaying vegetation. For best results, apply Beetlejuice directly to these breeding sites. While Beetlejuice can be used on tree trunks, it is less effective there as it thrives in moist, decomposing material.​

How the Beetlejuice spray Works

• The spores land on a beetle’s body and germinate in mulch or soil.

• The Beetlejuice fungus grows inside the insect, producing natural toxins.

• CRB die and new spores erupt from their bodies, ready to infect others, repeating the cycle for weeks or months in cool, damp areas.​

Benefits

• Certified organic beetlejuice formulations available

• Safe for humans, pets, pollinators, and earthworms​

• Self-sustains in the right, moist environment

For best long-term results, use the spray alongside proper mulch management, sanitation, and trapping—the foundation of integrated CRB pest management in Hawaii.​
