Cyzmic CS Insecticide
Product Review (submitted on January 4, 2020):
I used Cyzmic to spray a friend's house that had a major spider infestation. Spiders and webs everywhere, looked like Halloween. The old house had never been sprayed. I gave the exterior a triple treatment, and the interior a single treatment. Visited six months later. Significant difference. I located a few webs, but did not see any spiders. Much improved. I gave the exterior another single treatment. Will probably take several applications, but this product clearly works.
