Researchers at the University of Adelaide found, however, that secretions from the dumpy tree frog are more effective in warding off mosquitoes, and hold potential as a natural mosquito repellent. In their study published in the latest issue of Biology Letters, mice given these secretions remained bite-free for approximately 50 minutes compared to 12 minutes for the untreated group.

Additionally, two other species - the desert tree frog and Mjoberg's toadlet - released mosquito repellent odour from their skin, although their secretions were not tested.
