Electronic mosquito repellers attract mosquitoes

Isaias Cabrini and Carlos Fernando S. Andrade (Universidade Estadual de Campinas, Sao Paulo) report trials of commercial devices claiming to repel mosquitoes. They conclude that generally mosquitoes, including Aedes aegypti, are attracted to these electronic devices (which the authors term negative repellency). They advise that "Because the manufacturers do not present data for efficacy, government authorities should regulate the commercialization of electronic repellers". The devices emitted frequencies from 7.2 to 22kHz.
