The dawn soap will breakdown the hard shell of the bugs body and then the Talstar P will kill them
Talstar P will do a great job for boxelder bugs! We do not recommend that you use soap with the Talstar P or any other insecticides. The Talstar P may be used to spray directly on the plant foliage and it can be used inside and outside of the home. Please take a moment to look at our "How to Get Rid of Boxelder Bugs" article for more detailed information about this type of pest.
