Citric Acid Vouchers

In an effort to mitigate the invasive spread of coqui on our island and protect our native habitat, and in partnership with Nutrien Ag Solutions in Hilo, this program offers vouchers for a 50-lb bag of citric acid at a discount to the public.

How to Order

Call our office at 808-961-2681 or submit a request form online. Vouchers cost $82.50 and can be redeemed at Nutrien Ag Solutions in Hilo. It is recommended that you call or complete a request form so we can ensure we have enough vouchers available.

Pick up and pay for your voucher in person at the HCEOC office at 47 Rainbow Drive or mail your payment to HCEOC and allow up to one week to receive your voucher via USPS.
