## Description

Syngenta Demon WP Insecticide 2 Envelopes Containing 4 Water-Soluble 9.5 Gram Packets Makes 4 Gallons Cypermethrin 40%

Review: Truly Effective Insecticide Treatment - My husband is a huge fan of this Demon WP Insecticide. We are constantly ordering it here on desertcart because the cost is reasonable and you get a good value for your money. My husband mixes one envelope of the Demon into a bucket with a gallon of water. The mixability of the demon and water is awesome and there is no seperation noticed. He then pours it into a pump up sprayer and sprays the slab around our house to treat for bugs. He also sprays all the ant beds in the yard and it's very effective at killing the ants. Whatever is left in the sprayer after he's treated all areas in the yard he just leaves the Demon mixture in the sprayer for the next use. This product is extremely versatile and has proved to be a valuable resource for treating all bugs and insects around our home. After the treatment, we immediately see dead bugs, insects, and ants, and the removal of these pests lasts around three months. We highly recommend this Demon WP for your extermination of pests around your home.

## Questions & Answers

**Q: I have 2 young kids.  Is it safe to spray this inside the house (around baseboards).  Getting ants this winter.**
A: I cannot say anything about the ants but I managed to exterminate cocroaches who are the great survavals. The substance have no smell and did not influence the state of health anyway ,though I used it all around the kitchen floor in all the corners and crevices.Nither of my family members complained. I had to repeat the spraying a couple of times until all the disabled creatures died out. I think that the substunce is magic. Very glad that I was recomended to use it.

**Q: Whats the difference in this active ingredient (cypermethrin) and Cyfluthrin?**
A: Cyfluthrin belongs to a class of insecticides known as synthetic pyrethroids. ... Cypermethrin belongs to a class of insecticides known as synthetic pyrethroids, found in Cynoff EC, Cynoff WP, Cyper TC Termiticide, Cyper WP, and Demon WP pesticide concentrates.   But that info really won't help you .      what product are you trying to compare with demon wp?   cy-kick?  

Both Cykick CS and Demon WP are great products.  When sprayed, Cy-Kick CS creates a thick barrier of microcapsules that is impossible for insects to cross without being exposed to a lethal dose of insecticide. Exposed insects pick up microcapsules on their hairs and body triggering a rapid release of the active ingredient, resulting in death. Cy-kick’s active ingredient Cyfluthrin is a pyrethrin, which means it is user-safe, environment friendly, and less likely to cause skin irritation than other active ingredients. Cy-kick CS is virtually odorless, and will not create a visible residue or stain when used according to the recommended label rate. 16 oz.

Demon WP insecticide is a wettable powder that is mixed with water. It can be applied as a crack and crevice and/or spot treatment for residual and contact control of ants, bees, biting flies, boxelder bugs, centipedes, cockroaches, crickets, earwigs, elm leaf beetles, firebrats, fleas, flies, millipedes, mosquitoes, pillbugs, silverfish, sowbugs, spiders, ticks, and wasps. Demon WP will leave a white residue on dark surfaces.   Cy-kick won't

**Q: My daughter has a bad infestation of roaches. Will this work?**
A: Best to use Maxforce magnum roach bait gel and gentrol point source igr discs Or advion roach bait gel and gentrol point source igr discs.   For roaches inside.

**Q: Does this keep stink bugs and keep them away?**
A: Yes, I spray all around my house, screens, doors etc and they stay away or die shortly after. None have made it indoors in 2 years.
