Product Review: CSI Bifen L/P Insecticide Granules 25lb The CSI Bifen L/P Insecticide Granules are a highly effective insecticide that is designed to control various pests in both residential and commercial settings. This product contains bifenthrin, which is a broad-spectrum insecticide that can kill or repel over 100 different types of pests, including ants, spiders, cockroaches, mosquitoes, and more. One of the key benefits of this product is its long-lasting effectiveness. The granules are designed to provide protection for up to 3 months after application, which means that you won't have to reapply as often. This can save you time and money in the long run, especially if you have a large area to treat. Another advantage of this product is its ease of use. The granules are easy to apply and require no special equipment or training. Simply mix the granules with water according to the instructions on the label and spray the mixture onto the affected areas. It's that simple! Overall, I would highly recommend the CSI Bifen L/P Insecticide Granules to anyone looking for an effective and easy-to-use insecticide.
