Community Coqui Control Program Update: October – December 2020

Posted on March 3, 2021 by Lissa Strohecker

The MISC Community Coqui Control Program  expanded during November 2020 with the addition of the Akoa/Ala Olu/Makaio neighborhood. Five Ha‘ikū neighborhoods are now participating in the community program. MISC also began offering community spray nights to groups of six or fewer residents. To get involved in community efforts, fill out this form: https://bit.ly/Community-Coqui-Control-Signup or call us: 808-573-MISC (6472).

  • Neighborhood participants and MISC staff after the first micro-neighborhood community coqui control night on Manuahi Place in Haʻikū

On November 19th, we held the first (online) meeting of the community coqui control advisory group. Participants included community leaders from four of the five neighborhood groups, plus a community leader not currently involved in the program. It was an excellent opportunity to bring the leaders from the different communities together and get their feedback. Terry Tolman from the Lower Kokomo neighborhood said that the coqui spray weeks “are like a barn raising with the community working together.” John Phelps raised concerns about potential impacts to the program if the pandemic affects funding. Interestingly, nearly all of the community leaders have no coqui frogs on their properties yet put in many hours of effort to control coqui in their neighborhoods. Mahalo to all of the participants in our community coqui control advisory group!

Five neighborhood groups are now participating in community-based control: Haʻikū Hill, Haʻikū Mauka, Haʻikū Makai, Lower Kokomo, and the Akoa/Ala Olu/Makaio neighborhood. The Akoa/Ala Olu/Makaio neighborhood held their first community spray week during the second week of November with eight residents participating. We hope more people will get involved as they become aware of the program. Mahalo to Bonnie and Bill Prucha for spreading the word about the program and taking charge to spray coqui around the neighborhood!

  • A resident from the Haʻikū Makai neighborhood applies the 14% citric acid solution to areca palms in his backyard to control coqui

We held eight community spray weeks and three community spray nights during the fourth quarter of 2020. According to John Phelps, the captain of the Haʻikū Hill neighborhood, “Spraying each month has reduced the number of frogs on each property from hundreds to only a handful.” Community participants contributed at least 140 hours of active spraying and many hours of handling logistics, including contacting neighbors, picking up and returning equipment, and other behind-the-scenes activities. Community participants sprayed 14,255 gallons of 14% citric acid solution between October and December.

We are now offering the program to micro-neighborhoods, small groups of six or fewer neighbors working together. MISC staff provide the sprayer and training and then assist with efforts as needed. We started working with three of these micro-neighborhoods in 2020. One community person handles the logistics of rallying neighbors to participate. We will continue to work on a six-week recurring schedule and look forward to expanding this option to more areas. 

The community coqui control program has grown to three staff: a coordinator and 1.5 FTE liaisons, with the addition of Carl Schwarz as a full-time position. This increased capacity is allowing us to offer the program to more residents. The community coqui control program works closely with the larger coqui crew, which mix and deliver the citric acid solution to reservoirs staged in the neighborhoods. They also drop off equipment and treat areas that are inaccessible to community participants.

Community participants received over 930 pounds of powdered citric acid through our no-contact powdered citric delivery program. Participants performed coqui control activities on 96 properties; if you need citric acid for coqui control on your own property, let us know through this form (https://bit.ly/Coqui-Maui-Public-Report-Form).

Removing frog-friendly habitat is a key element of coqui control and proper disposal of green waste helps prevent the spread of coqui frogs (and other invasive species). Through our partnership with Maui Disposal, we provided free green waste bins to the Lower Kokomo and Haiku Makai community coqui control neighborhoods. More than 5.5 tons of green waste were removed under this program!

Haʻikū Residents bring back quiet nights through MISC Community Coqui Control Program

Posted on December 4, 2020 by Susan Frett


Haʻikū communities are taking back their quiet nights from noisy, invasive coqui frogs, with tools and training from the Maui Invasive Species Committee (MISC). MISC is currently working with five Haʻikū neighborhoods –Haʻikū Hill, Haʻikū Mauka, Haʻikū Makai, Lower Kokomo and Akoa/Ala Olu/Makaio. The program is ready to assist and empower more Haʻikū residents in the fight against this invasive species to protect their way of life and health of our native ecosystems.

Ha’ikū residents support each other in controlling coqui frogs on their properties with support from MISCʻs Community Coqui Control Program.

MISC recognized that in addition to strong support from the County of Maui and State of Hawai’i, containing and eradicating coqui in Haʻikū would require strong engagement at a neighborhood level. MISC launched the program to support and expand on existing community coqui control efforts by residents. MISC provides training, equipment, and citric acid solution (a food additive mixed with water). Community members provide boots on the ground – removing vegetation, hauling hoses, and dousing infested areas with citric acid solution. And it’s working. According to Haʻikū Hill team leader John Phelps, “Spraying each month has reduced the number of frogs on each property from hundreds to only a handful.” Neighbors working together can be more effective than independent control efforts, as coqui can quickly move into untreated areas or reinfest properties without a consistent effort. Participants report an additional benefit: the program is a good opportunity to get involved and meet their neighbors. MISC follows all social distancing and mask-wearing protocols whenever working in the community and all control work is conducted outdoors.

MISC provides different levels of support, depending on community need and participation. Individual residents can receive free powdered citric acid to control coqui on their property once MISC has confirmed that coqui are present. Residents can also borrow a 9-gallon walk-behind sprayer or a 100-gallon sprayer that fits in the back of a pickup truck. MISC provides training on how to effectively use the sprayers. 

When three or more neighbors agree to work together across their properties, MISC provides a 100-gallon sprayer to participating residents every six weeks and helps residents with spray operations if needed. For larger groups of neighbors (at least nine committed households, plus a person  who serves as a point of contact) MISC provides a reservoir of pre-mixed citric acid during the specified control week on a six week rotation. Participants report that having mixed citric acid in advance has been a “game changer” as it allows the team to focus directly on control activities. In two neighborhoods, the community groups proposed using a pipeline to effectively treat a larger area. MISC and the residents worked together to design and install the systems.

MISC provides a variety of sprayers to residents wanting to control coqui frogs on their properties.

Over the years, MISC has been able to eradicate 21 coqui populations on the island. Abe Vandenberg, MISC Coqui Field Coordinator, says the key to those successes has been persistence and consistency. He emphasizes the importance of community efforts, noting record levels of participation last summer, “Local engagement is a huge help to the island-wide coqui control strategy. As more community members help remove coqui from their own backyards, they allow MISC staff to take on more challenging work in the gulches and other areas with difficult access. Working the process of small wins will lead us toward the biggest possible success –  a coqui-free Maui.”

Community Coqui Control Progam – September 2020

Posted on September 23, 2020 by MISC

All four of the Haʻikū neighborhoods involved in the MISC Community Coqui Control Program held work weeks during August. One of the communities, Haʻikū Mauka, had record participation: the community worked together to treat half the properties in the neighborhood and collectively contributed 24 hours of effort helping each other remove coqui frogs. 

In the Lower Kokomo neighborhood, more residents learned how to operate the citric acid pipeline that is installed in their neighborhood gulch, further empowering them to keep the coqui frogs out of their backyards! 

Haʻikū residents work together to bring back quiet nights to their neighborhoods.

The MISC Community Coqui Control team held the first  Virtual Block Party with the Lower Kokomo neighborhood. MISC staff presented results of their neighborhood effort over the first year and discussed future plans for the program. The highlight was that the community reported hearing fewer coqui frogs in the neighborhood since the program began! MISC plans to hold Virtual Block Parties with each of the neighborhoods we currently work in before the end of the year. 

MISC will continue community spray weeks on a  6-week rotation through the fall. To further empower local residents to control coqui frogs in their own yards  MISC is offering small, in-person training sessions to learn how to use the equipment available from our community loan program. Community members with coqui frogs in their yards are encouraged to recruit a few neighbors and contact Susan (skfrett@hawaii.edu or 808-633-6646) to sign up for this training opportunity. Participants will learn how to use different sized sprayers, mix the correct percentage of citric acid solution, safely treat their yards and clean the equipment.  Any efforts that community members can take to control coqui frogs in their own yards frees up the MISC coqui crew to work in the gulches and other challenging locations.

Coqui – April/May 2020

Posted on May 27, 2020 by MISC

As preparations were being made for MISC’s coqui crew to safely do fieldwork during Covid-19, the field crew had the opportunity to have an extended experience of MISC’s “Coqui College.” Utilizing virtual meetings, the crew met daily in video and voice chat rooms. They created site response plans, trained new staff, and watched selected presentations from prior Hawai’i Conservation Conferences. Our current crew includes Abe Vandenberg, Coqui Crew Coordinator; Darrell Aquino and Scott Winter, Field Crew Leaders; and Megan Archibald, Teri Green, and Kayani Singh, Field Crew. MISC is currently hiring additional staff. 

Additionally, MISC’s new Coqui Community Engagement Coordinator, Susan Frett, joined Beth Speith on the coqui community project in early March. While unable to engage directly with community members in person due to Covid-19, they developed and implemented an online questionnaire to determine how MISC could further empower community members to control coqui frogs in their yards. Susan and Beth collected, analyzed, and are now following up on feedback to improve the community program going forward. 

Based in part on questionnaire responses, the crew has been out hunting down single frogs, doing habitat work, and spraying smaller amounts of citric to tackle outlying single frogs and small populations. One response alerted the crew to a previously unknown small pocket of frogs in a challenging wildland location. This area likely expanded from a known population of frogs in Haʻikū and is now being controlled. The resident who initially reported this infestation sent this update: “I woke up at 3 am and took a moment to listen outside. I didn’t hear any coqui! I will listen again this evening. Mahalo to you and the crew!”

For a full report on what we learned from the questionnaire please check out this blog post: Results from the coqui community engagement questionnaire

At the same time, the coqui community team has been busy empowering residents to control coqui on their own. The team is distributing citric acid use for frog control using the no contact food delivery model. Between April 17th and May 9th, MISC staff delivered 633 pounds of citric to 17 separate locations around Haʻikū so residents can control coqui in their own yards. Citric deliveries will be available for as long as the MISC baseyard remains closed to the public. Small (1.28 lb) and large (50 lb) bags are available for residents to use in their own yards. Please get in touch with Susan at (808) 633-6646 or skfrett@hawaii.edu to request citric if needed.

No Contact Citric Delivery

As the weather continues to warm into the summer months the frogs will be more vocal. Please let us know what you are hearing especially if you hear them in a new area. We cannot always respond to reports right away but do prioritize responding to reports of frogs in new areas. Please report if you hear frogs where you haven’t heard them before. As this Maui resident said, “this neighborhood does not have coqui frogs YET.  If I were to hear one or more I would immediately inform my neighbors and urge ACTION!” Thanks for your enthusiasm! 

Report coqui frogs using the MISC Coqui Report form.

Community reporting alerted MISC and the Hawaii Department of Agriculture to coqui frogs at a larger nursery in central Maui in mid-May. Check out the story on our blog!
