FOAMING TREATMENT is the answer for areas that are difficult to treat such as under slabs, outside steps, around rubble foundations, behind veneers, interior voids (walls, chimneys, masonry), plumbing accesses, and around air returns. Foams or air bubbles result when air is forced into the termiticide and foaming agent; at contact with the structure, the foam disperses the solution into every fill and void, ensuring maximum coverage. Foaming treatment prevents termites from seeping through edifices and discontinues termite activity in your home or dwelling.
