Loose mites or fruit flies have you down? Then step up with Bug Blade, an all-natural powder from Josh's Frogs that will stop bugs in their tracks. Made of diatomaceous earth, Bug Blade will form a barrier that all kinds of small insects and other invertebrates will be unable to cross. Simply spread a thin layer of Bug Blade around the base of your vivarium and prevent escapee fruit flies from crawling to freedom! A small amount of Bug Blade around the base of fruit fly cultures will prevent the movement of mites from culture to culture. Bug Blade is also effective in protecting your vivarium from ant invaders!
