Coqui Information

Sounds
If you can hear the sound of one coqui, the odds are extremely high that you already have more than one frog and a resident population. Females and juveniles live on the ground and are silent. A mature male is the only coqui that sings, and he does so from dusk to dawn. By comparison, the sound of a leaf blower is about 75 decibels. The sound of a coqui can reach up to 95 decibels. He does this to attract females and to warn other male coqui of his territory. During the day, males are on the ground, as well, protecting the eggs.

We are not an extermination service.
To best understand this, it is necessary to know some fundamentals of the coqui biology.
Coqui are native to Puerto Rico where they are kept in check by natural predators, which include snakes and tarantulas. Hawaii obviously doesn't have these species so the frogs go unchecked. This is compounded by the fact that females lay clusters of eggs approximately every 2 1/2 weeks; each cluster or "clutch" of eggs numbers between 30-75 eggs. The mortality rate is only 2%, which means that 98% of these eggs will hatch. Given that on any given day a female can be laying eggs, their numbers can increase exponentially at a very rapid rate and become overwhelming if left unabated.
