The latest new product is a spray or brush on resin that the company claims stops scorpions from getting into your home. The above video clearly shows scorpions climbing on their product high enough to reach the weep holes or footing seam.
The Scorpion Repel product will cut down on entry but will not eliminate it 100% as the Pest Border Barrier will. In addition they do advocate pesticide treatment even after applying their coating. This product has a limited life span on your home and will yellow from the sun. Being that it is a new product with very limited background the results remain to be seen.
