Tempo SC Ultra is labeled for termites. Please take a moment to review our SubterraneanTermimte Treatment Guide for more information on implementing a successful treatment plan.
Termites are not a surface dwelling insect, so applying insecticide sprays, such as Tempo SC Ultra to the foundation will not be a work. We have a step by step guide that will walk you through how to do your own termite trenching treatment. You can see the guide by clicking on the link here. Termidor SC would be the top product to use for the trench.
Tempo SC Ultra will kill termites above ground but will not replace a soil application or wood treatment. When treating for subterranean termites you would want to do a soil treatment with a termiticide like Termidor SC. If you are treating for drywood termites we recommend using something like Bora-Care to treat raw wood. Please look over our guides on Subterranean Termites and Drywood Termites for more information.
Tempo SC and Demon Max should not be tank mixed. You should use one or the other as directed on the label for the targeted pest/area treating. Please take a few moments to review our treatment article on How to Get Rid of Termites for a successful application with suggested products.
