Permethrin is the best choice all around for general outdoor spraying. Termidor or fipronyl is not labeled and not recommended for general spraying and will burn trees and cause the leaves to drop and fall off.
Termidor is the best overall treatment for termites, but should only be applied as a soil or a wall void treatment.
So basically, you will need both products to do what you are wanting to do.
Masterline is a Univar private label brand. Bifenthrin is only 1 of the many products that Control Solutions private label bottles for Univar. I am surprised that you can't get any Bifenthrin products, but you can get Fipronyl. I would check the chemical labels and look at the active ingredient on each bottle and see if you can find one that says - Active Ingredient: Bifenthrin.
