Hawaiian officials are happy now that the EPA has temporarily approved the use of hydrated lime to combat coqui frogs (Eleutherodactylus coqui). As reported by The Maui News, hydrated lime is much cheaper than the currently used citric acid, and has the added benefit of not having to be applied directly on the frogs. Of course, hydrated lime dust can also be caustic to other animals, including humans, and it can raise the pH of the soil. Should be interesting to see if lime application has any long term impacts on the fragile island habitats.
