Can't dig trenches through rock. Is this a spray termiticide?
When spraying outdoors around the foundation Navigator SC Termiticide/Insecticide can last up to 4-6 months and then will need to be reapplied and is only for treating general pests like ants, roaches etc. You can apply Navigator SC as a perimeter spray up to 4 times per year: Twice at the 0.8 oz./gal rate; 4 times at the 0.4 oz. per gallon rate; or 3 times, spraying once at the 0.8 oz. rate and twice at the 0.4 oz. rate.For termite prevention it must be applied in a trench in the soil adjacent to the structure. We have a step by step guide that will walk you through how to do your own termite trenching treatment. Spraying on the surface is not effective for termites as they are inches below the soil when they are foraging and do not contact the direct surface.
