01 / LISTEN & RECOGNIZE

A little frog.
An unmistakable call.

Coqui are small, mostly brown frogs. Males make a high, two-note “ko-kee” call at night. Their persistent calls and effects on native ecosystems make early reporting valuable on Maui.

02 / REPORT DIRECTLY

You heard it.
You’re the best contact.

Share what you heard or saw with the responding organization. Use your own contact details so staff can ask questions and follow up with you.

Before you report

  • Where? Address or location, nearby landmarks, and where the sound seems to come from.
  • When? Date, time, and whether you have heard it on more than one night.
  • What? Say whether you heard or saw it. Include a recording or photo if you have one.
  • Who? Your name, phone number, and email for direct follow-up.

You can report a suspected call without first seeing or catching a frog. Describe any uncertainty.

03 / CARE FOR YOUR PROPERTY

Small steps.
Less room to spread.

Start with MISC’s current advice. Regular attention to plants and green waste helps reduce places where frogs can hide.

01

Check plants
before moving them

Inspect new plants. If plants may contain frogs or eggs, keep them in place and ask MISC about treatment before moving them.

MISC treatment guidance
02

Reduce hiding
and nesting places

Thin dense vegetation and remove accumulated dead leaves and plant debris. Handle green waste carefully so frogs and eggs do not travel with it.

03

Get guidance
and equipment

MISC offers treatment guidance, citric acid, and sprayer loans. Request supplies directly and wait for confirmation before pickup.

Moving green waste?

Ask MISC how to handle potentially infested material before transport. Never dump it in gulches or vacant lots. Check Maui County’s green-waste disposal information ↗ for approved options.

Follow current product labels and MISC safety instructions. Get permission before entering or treating someone else’s property. Read MISC’s current community program guidance ↗

A FEW COMMON QUESTIONS

Know your
next step.

I hear it, but haven’t seen it. Can I report it?

Yes. Describe the call as suspected coqui, note the location and time, and share a recording if possible. You do not need to identify or catch the frog yourself before contacting MISC.

Will someone come to my property?

MISC assesses reports and prioritizes its available resources. Reporting does not guarantee a visit or treatment. Its current program supports residents with advice, supplies, and equipment; residents coordinate their own treatment activities. See current assistance options ↗

What if the sound comes from a neighbor’s property?

Report what you can hear and the approximate location directly. Do not enter or treat another property without permission. Keep reports factual and share location details privately with the responding organization.

Should I send my report to WCE management?

Please submit your coqui report directly to MISC or the state reporting system and remain the contact for follow-up. If you also have a concern involving association-maintained property, you may separately notify management of that property concern.
