Volunteers on Oahu have caught thousands of invasive coqui frogs by hand in Waimanalo, a small win in a fight against a pest that costs Hawaii billions in damage and lost income.

• A volunteer frog task force has captured more than 3,800 coqui frogs in Waimanalo over two years.
• The goal is to stop the loud invasive frogs from spreading further across Oahu.
• Invasive species cost Hawaii billions of dollars in damage and economic losses.
• The work is being done by hand, one frog at a time, rather than through large-scale eradication.

Outlook: Volunteer capture efforts are expected to continue and expand as the group pushes to contain the frogs before they take hold island-wide.
