Don't waste your money on any other insecticide. Excellent. *by I***P on August 11, 2026* A professional exterminator told me about Demon, probably 20 yrs ago. Been using it ever since. The ONLY DIY way to go. You won't use anything else after you try it. Buy a 2 gallon plastic tank sprayer for $15 and drop a packet of water soluable Demon into it. It annihilates ant hills, termites if you have them, fleas, palmetto roaches like here in FL. Fortunately, they die a swift death with Demon. Spray it around the outside of your house as well. Or put it in a hose end sprayer if you have a flea problem in your yard. Guaranteed gone. Spray some behind your refrigerator and range, etc., if you notice a roach, but you won't after using this stuff. Oddly enough, if you spot spray your cabinets under the sink or closets, my cat has never been affected. ## Frequently Bought Together - Syngenta Demon WP Insecticide Containing 4 Water-Soluble 9.5 Gram Packets Makes 4 Gallons Cypermethrin 40% (1 Envelope) - Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White - Syngenta Demon WP Insecticide Containing 4 Water-Soluble 9.5 Gram Packets Makes 4 Gallons Cypermethrin 40% (2 envelopes) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/16269333-demon-wp-insecticide-1-envelope-containing-4-water-soluble-9](https://www.desertcart.be/products/16269333-demon-wp-insecticide-1-envelope-containing-4-water-soluble-9) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-21*
