Fogging is great to pretreat bins and control bugs in warehouses or mills.  Done regularly in enclosed areas, the process can keep bugs from infesting grains, feeds & seeds.
Since 1 gallon of Inselux will treat 64,000 cubic feet (50,000 Bu Bin), this bundle (including the free fogger $300 value) will treat 1,152,000 cubic feet of space or 925,000 bushels of space.
