Demon WP Insecticide
- Product Review (submitted on February 1, 2020):
- I have been using this Demon for many years. We have a lot of water bugs coming out in the spring. I spray inside and outside including around my windows and doors. I was told by an exterminator to switch back and forth between the powder and liquid. I really don't have to spray but once a year. The only bugs I see are the dead ones. Can't really say anything but great about this product.
