An ad agency I was working with a decade ago presented, as part of a new round of work, a rough cut of a crazy video featuring a frog, hot pink background, and loud pulsating music by Joan Jett and the Blackhearts.
One recent weapon is what frog-busters are calling a "hot shower chamber, " a modified freight container used by nurseries to ship plants, with multiple heads that spray heated water onto the plants and kill any coquis that might be lurking there.
