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

My husband is a huge fan of this Demon WP Insecticide. We are constantly ordering it here on Amazon 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.

If you have spiders and want them gone this is the way. If you have grasshoppers this will make them go away scorpions don’t like it and you can even use it on fire ant mounds my family sprays it all along the baseboards in our homes to keep unwanted insects out Thank you Demon WP

I’m familiar with the active ingredient (cypermethrin), and I know it’s a very strong insecticide, so I expected it to be effective — and it definitely is. After treating my garage, I kept finding dead insects, especially cockroaches. It works by paralyzing them, so once they come into contact with it, they can’t move anymore and die right there. What surprised me the most is how long it lasts. Even after about a year and a half without reapplying, it was still effective in an enclosed space — insects were still dying from the treated surfaces. I also had some diluted solution left in a sprayer, and I used it later around the entrance of my new apartment and in the hallway. It still continues to work — insects step on it and die, even though the mixture was prepared a long time ago. For outdoor use, of course, it would need reapplication more often because of rain and exposure, but in enclosed areas it lasts a very long time. Overall, I highly recommend it. I’ve tried other liquid treatments before (even for mosquitoes around patios and fences), and this type of formula has always been the most effective for me.

Very happy. When applied to ant mounds I can see dead ants. Love this product. Have and will keep buying this product.

Product works well

Ok, I am ordering more Demon WP , always keep some around for spraying for bugs, was turned on to this stuff when we lived in Florida, very pleased with the results. We had Palmetto bugs in Florida , (some call ‘em roaches) some were so large & they happen to run across the airport runways , the fuel guys would ride out to fuel”em up thinking they were airplanes. But, in closing I’ve used this since 1996, it works. Live in NC now and still use it .

Amazing, I have using this for 3 years, and it does the job. You want see anything crawling for at least 6-9 months. No odor, safe for kids and pets. No stains and you can spray anytime. Anywhere.

To say this works well is an understatement. Simple yet effective I highly recommend!!!!
