  • Demon WP Insecticide For Insect And Pest Control
    By David Goodrow on 1/10/2016
    Tried Demon a few years ago because of a flea problem and Demon killed all the fleas, inside & outside. Continues to kill fleas and everything else for months. 98% smell free and safe for inside use. Very good product.

  • Demon WP Insecticide For Insect And Pest Control
    By Reagan Koons on 11/2/2015
    I've been using this product for a long time. So long I forgot how many years. It works great both inside and outside around the house. I'm glad I found y'all because it was becoming cost prohibitive for me to go to the local farm and ranch store. Y'all made it possible for me to save enough money to buy my annual amount of Demon WP. Thanks a bunch. Now if I could get a recommendation for a product that would deter varmints such as skunks, 'coons, possums from digging under my house I would appreciate it. Thanks again.

  • Demon WP Insecticide For Insect And Pest Control
    By Richard Getteau II on 8/15/2015
    After getting stung one time in the middle of the night, I have been using this in and around my deer lease trailer for the past couple of years. It works great and on the rare occasion I see a scorpion in the trailer, he's already dead. It also kills pretty much anything else. So that also helps to keep the scorpions away.
