Caffeine Croaks the Frogs

posted on October 5, 2001


A morning cup of java may give you a wake up jolt … but it can "croak" a frog. The Environmental Protection Agency has approved the use of caffeine to kill tiny Caribbean tree frogs, which have infested 226 sites on the Big Island of Hawaii. Pure caffeine is used in a spray form and causes the amphibians to have cardiac failure. The frogs, native to Puerto Rico, are about the size of a dime, but each male chirps up to 90 decibels … which is comparable to the noise level of a lawn mower. ######################
