                  FEATURES & BENEFITS

                  • Broad pest spectrum provides “cupboard to curb” control of more than 90 insects with a single product.
                  • Application flexibility allows Tandem to be used indoors for residential and commercial areas and outdoors for perimeter or spot treatment for general pests, and full yard treatments for turf pests. Tandem can also be used in food-handling establishments, as directed by the product label.
                  • Patented iCAP technology protects the  active ingredient in various capsule sizes to ensure controlled release and durability against harsh environmental conditions.
                  • One product tackles a broad range of pests and eliminates the need to carry multiple products on a technician’s truck.
                  • Application as a spot, crack-and-crevice, void, banded spray or full yard treatment makes it flexible for technicians to use in any way needed.
                  • Controlled release of the active ingredient provides immediate and residual control lasting up to four months, giving customers a peace of mind and ensuring control will last through quarterly service protocols.
