Since both products contain synthetic pyrethroids there is no valid reason to mix Suspend SC and Tempo together, it would not make either product work better or produce better results, though it could make treated areas repellent to insects lessening the effectiveness of the treatment. Instead you may want to choose a product that has dual active ingredients such as Transport or Temprid. This will help avoid any type of resistance issue since both of the products contain two active ingredients from different classes of insecticides.
