D-Fense SC Insecticide
Product Review (submitted on July 25, 2017):
We had major issues with boxelder bugs and occasional issues with other common pests. Treating with the big box store insecticides just didn't cut. One application of D-Fence along the walls and crevices put an end to the problem within a few days.
I also use this product along the exterior foundation as an added layer of protection.
There is no odor and the product lasts for several months before I reapply. If you don't have a pump sprayer they sell them here. The product is not messy to mix and a little goes a long way.
