Hawaiian Residents Kept Awake by Invasive Frog Croaks as ‘Loud as a Jet Airplane’

Invasive Coqui Population in Hawaii Concerning Officials

HONOLULU (AP) — The coqui is a tiny, coin-sized frog whose distinctive nightly mating calls are a beloved sound in Puerto Rico and other Caribbean islands. But people in Hawaii don’t share the same sentiment.

The frogs have been growing in population in the state in recent years and are now starting to show up in larger numbers on Oahu — home to most of the state’s population. The frogs already have a strong foothold on the less-populated Big Island, and people there complain of being kept awake at night with a thunderous roar of chirps as thousands of male coqui simultaneously summon partners — a mating chorus some say can be as loud as a jet airplane.

Listen to this recording of the frogs:

The frogs are also preventing the state’s plant nurseries from exporting to some markets, and depressing some Big Island property values. The frogs aren’t stopping tourists from visiting, but there’s a fear they could if they spread further.

There have been just as many reports of coqui on Oahu in 2011 as the seven prior years combined, said Derek Arakaki, who helps hunt coqui frogs for the state Department of Agriculture. Before, Arakaki and two others on the coqui-eradication team would head out to capture the frogs on Oahu once a month or maybe twice a month. This year, there have been times when they’ve had to go coqui hunting twice a week.

The frogs are a significant problem in their non-native Hawaii because the state has no natural predators to stop their advance. As a result, they have spread quickly through the lush forests and yards near Hilo since they were accidentally introduced to the Big Island in the 1990s. They have been making a steady advance into the more heavily populated Oahu in recent years, sneaking onto the island on plants and stowing away in cars, piles of lumber, cargo pallets and whatever else that’s being sent to Honolulu.

Invasive Coqui Population in Hawaii Concerning Officials“Compared to the amount that’s on the Big Island, very few are actually getting through,” said Carol Okada, an Agriculture Department plant quarantine manager who heads the state’s efforts to control invasive species. “But the amount that’s getting through is still enough to establish a population, so we are still very concerned.”

Coqui, which get their name because of their “ko-kee” chirps, are showing up in diverse places. The International Marketplace outdoor bazaar in the heart of Waikiki, the state’s tourist mecca. Near a banyan tree in front of a multiplex theater. Seven coqui were found in a home in the upscale Diamond Head neighborhood. The residents had brought back some plants from the Big Island not knowing they needed to be inspected for coqui before shipping them to Oahu.

Coqui eradication team members spot them by mimicking their mating call, which prompts the frogs to call back. They hone in on the sound and trap the frogs with a clear tube. Sometimes, they’ll spray water to entice the frog to sing.

In a few cases, the coqui team has found so many frogs they’ve had to kill them with citric acid, the preferred chemical for eradicating the frogs.

That was the case in the rural windward Oahu town of Hauula, where coqui had spread out across several homes and a city park. Residents there heard nocturnal chirping, but didn‘t call the state’s pest control hotline because they thought birds were making the sounds. By the time the authorities were notified, the frogs had been around and breeding for two years. It took the crew several months to get rid of the infestation.

The problem is only made worse by recession-induced budget cuts that forced the state to slash the number cargo inspectors to 50 from 95.

This caused the Agriculture Department to prioritize checking out-of-state cargo, because imports are more likely to carry harmful species like snakes — an animal that hasn’t become established in Hawaii.

Okada said the state will have to capture more pests that get through because there haven’t been enough people to spot them at the ports.

“When you’re not at the front end, you end up chasing it on the back end,” Okada said.

The state has had this problem with snakes, which could wipe out Hawaii’s native endangered bird species they ever became established here. A dozen — from boa constrictors to ball pythons — have been either captured or turned in to authorities since July.

“There’s a reason why all the snakes are coming out this year. We’re not out in force anymore,” Okada said.

Gov. Neil Abercrombie enabled the state to hire 10 more people to bring the inspector count close to 60, but Okada said they’re still far short of where they need to be to effectively intercept pests entering Hawaii or traveling inter-island.

Okada said one scary thing about this past year was that many coqui were found closer to the base of Oahu’s heavily forested mountains. The coqui population could explode if they started breeding somewhere like the back part of Manoa valley, where it frequently rains.

Authorities are asking the public to call the state’s pest control hotline if they think they hear a coqui.

    Someone needs to create a tasty dish out of the frog and charge ridiculous amounts at all the best restaurants for very small portions. The frog would be hunted to extinction within a few years and have to be protected by the greenies.

      I lived on the Big Island for four years between 2001 and 2005. When we first arrived there were NO coqui frogs at all. By 2005 they had infested Kapoho where we lived which is situated near the world famous tide pools. Now, as the sun begins to set they are SO LOUD you have to close your windows which eliminates any air circulation in your house because there is no air con there (that is affordable). Believe me when I say it is extremely painful to your ears. You can’t sleep at night because they call all night until sunrise and sometimes even after.
      It really is damaging the real estate and tourist market to the point where many people will never return to that beautiful area simply because of the frogs. You can‘t drop cats in because they won’t eat frogs..too bitter and besides the mongooses kill and eat the cats. The only way to stop them is spray bleach or citric acid directly on their skin. Period. Trust me, you don’t want them in your yard.

      Funny that after all that journalistic rhetoric, in Puerto Rico where the Coqui frog is from it venerated in many ways: if you catch one means good luck, is thwe only frog that doesnt have a tadpole stage but is fully formed right out of the egg, the male takes care of the babies, and best of all Puerto Ricans go to sleep in peace to the sound of the Coqui frog as if ther is no chirping means that something or someone lurks in the darkness. They have no crisis nor overpopulation in PR, it is the most adorable and friendly specie. No other place in the world has Coqui frogs as they are indigenous of PR and for many centuries believed that it would die inmediately after leaving the island. Apparently a puertorican was able to do what many scientist have failed in. Relocating the frog succesfully. This frog is a blessing to all the people of Puerto Rico and a bad omen to whomever attempts against the tiny frog. The Government of Hawaii must have discovered that Coqui frogs are traditionalist conservatives from PR and that is why they are suppressing their Freedom of Speech. Hawaii, if you mess with the Coqui, you are doomed for certain destruction. You have worse things to deal with such as crime and the high cost of living and the fact that Obama allegedly was born there. They are a National Treasure! Get rid of Wayne Newton first!
