Termidor Foam is an excellent termiticide/insecticide for use in and around structures and limited outdoor spot treatments.  For treatment of known or suspected galleries, harborages or wall voids.  Use with Termidor SC.  

Ideal for treating both subterranean and drywood termites as well as ants.  It's also highly effective on carpenter ants.  The unique formulation offers better control and coverage with thicker, stronger cell walls that stay intact up to six times longer than other foam termiticides.  And because the foam cells resist breaking, it’s less likely to run.
