    Great Product

    Demon WP always does a great job of keeping the bugs out of our house. We've used it for many years. We have tried other insecticides at times, but we always come back to Demon WP. Nothing beats it.

    Great product!

    This is a great product! I have been using it for years and I never see any bugs in or around my house! I used to have lots of waterbugs outside my house at night. And occasionally I would get ants inside. Since I have been using demon WP, I have seen any at all! Great product, and the price is just as great! Thank you!
