Growstone Gnat Nix! Options:Growstone Gnat Nix! 9 Liter Bag Because perlite is sterileGnat Nix! controls gnats at different points of their lifecycle, therefore preventing adult emergence from hatching larvae and deterring females from laying eggs in the growing media. As a result, their lifecycle is interrupted, and its population significantly reduced. Like all Growstone products, Gnat Nix! is made in the USA from 100% recycled glass.
