With the chemical, deet currently dominating the mosquito-repellent market, the scientists are looking into nature to find an alternative. An Australian researcher-team has isolated yet another natural mosquito repellent, claimed to be one of the most effective — from an unlikely source — smelly frog skin.
To isolate this chemical used to make the repellent, Williams along with his colleagues have used low levels of electric current to the skin of five different Australian frog species. And the resulting current caused them to expel larger amounts of their natural secretions than they normally would have, using it to make the effective and natural repellent.
We can call the product totally eco-friendly, only if the frog is not killed or diseased in the process.
