Bio-Repellent Scientific Industries (BRSI) is a California-based company specializing in the development and manufacturing of non-toxic, environmentally friendly pest control solutions. The company is best known for its patented "Deter" product line, which utilizes food-grade ingredients to repel birds and other pests without causing them physical harm. BRSI's technology focuses on sensory-based repellents that stimulate the trigeminal nerve of pests, creating a sensory aversion that discourages them from nesting or congregating in treated areas. Their products are widely used in commercial, industrial, and residential settings as a sustainable alternative to traditional chemical pesticides and are recognized for being NSF-certified.
