There’s no need to use toxic substances to kill off unwanted insects in Japan, because there’s a much more eco-friendly method they’ve been using for hundreds of years. Although it may not be scientifically proven, many people feel this is still the best way to get rid of everything from garden aphids to mosquitoes. And if the method has endured for centuries, it must be at least somewhat effective right?
This uniquely Japanese insect repellent is far cheaper than commercial insecticides, easier to implement, and you only have to use it once a year in spring or early summer. And the best part? It involves Japanese sake!
What’s the secret? We’ll let you know after the jump.
