How Cyper WP Insecticide Works

Cyper WP is a residual insecticide concentrate with the active ingredient Cypermethrin. Cypermethrin is in the synthetic pyrethroid class of insecticides. It is a man-made active ingredient that attacks the central nervous system of insects that come in contact with or ingest it. Cyper WP is diluted with water and applied with a gallon pump sprayer. After it dries, Cyper WP continues to work for up to 3 months.

Cyper WP Target Pests

A variety of crawling and flying pests including (but not limited to) ants, carpenter ants, cockroaches, crickets, scorpions, and spiders

PESTS CONTROLLED WITH CYPER WP: Ants, Bees, Boxelder Bugs, Carpenter Ants, Carpenter Bees, Centipedes, Chiggers, Cockroaches, Crickets, Earwigs, Elm Leaf Beetles, Fire Ants (mounds), Firebrats, Fleas, Flies, Millipedes, Mites, Mosquitoes, Pillbugs, Scorpions, Silverfish, Sod Webworms, Sowbugs, Spiders, Ticks,  Termites (above ground only)

Target Uses of Cyper WP

Cyper WP (same as Demon WP and Cynoff WP) insecticide is a loose white 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.

Cyper WP has a residual of up to 3 months. 1 x 1lb. container of Cyper WP yields up to 48 gallons of finished product.

Cyper WP (Wettable Powder) is excellent for larger, tougher pests such as cockroaches, spiders, scorpions, or stink bugs because there is a high concentration of active ingredient. The wettable powder formulation also makes Cyper WP ideal for porous surfaces such as concrete since the individual particles of active ingredient are larger and can more easily stay on top of the surface.

*Cyper WP leaves a white powdery film that may be visible on darker surfaces. For applications where this is a concern, consider using a liquid concentrate instead.

ACTIVE INGREDIENT: Cypermethrin 40.0%

    Very effective

    By Pam on 04/02/2009

    I've used Cyper WP in my home in northern KY. It was very effective and me and my neighbors on both sides of my house used this product at the same time. It works better when you can treat inside and outside of your home. It's a lot cheaper than an exterminator. I repeat treatment about every 3 months to prevent the bugs from coming back. Thank you very much, I can now sleep at night without worrying.

    Cyper WP Works Great

    By Jim on 06/06/2010

    Verified Purchase

    Our Ranch house was infested with scorpions. We were advised Cyper WP would do the trick. We literally counted about 40 dead ones after the application and have seen only one or two that were acting very sickly. This stuff works. It actually has killed everything that crawls or flies when that pest comes in contact with it. I will be ordering more in quantity for friends and family. Thank You for having a bulk discount.

    The best I ever used

    By George on 08/03/2006

    Starting in 2005 I noticed late evening every night on my patio carpet several black bugs and identified them as Oriental cockroaches. In March of 2006, it became terrible. A friend looked on his computer and found that Niban bait was recommended. He gave me your number. My first conversation was with Michael and he recommended Cyper WP with the Niban. He told me to remember that Niban was a bait and not to use the Cyper WP near the Niban. I used a 3 gallon watering can with 4 scoops of Cyper WP, mixed good, to eliminate the nest which was in a long crack in our side walk, adjacent to our patio. I soaked the entire patio carpet, and the entire perimeter of our house. I put the Niban bait, sparingly, not closer than 25' to our sun room and patio. This type of cockroach loves water. I removed my landscaping bark which was always wet from watering flowers. I have since ordered 4 Cyper WP. It has been a good month and a half with NO black water cockroaches in our sun room. Once in a while I will find one on our patio carpet, on his back dead. The Cyper WP in also good for killing ants. The best I ever used. I have 1/2 acre of land so sometimes its a struggle. Thank you for all of your help.

    Cyper WP

    By Sean on 07/30/2010

    Verified Purchase

    Does exactly what it said it would do. I had a very bad spider (Brown Recluse and Wolf) problem inside and outside the house, within a day I saw no more living spiders in my house, period. Word of caution, pay attention to what it says about if you have dark floors. I do have dark floors and it leaves a very noticeable white residue. They have others for inside the house that are clear, i just didn't read thoroughly. Great Product.

    Cyper WP Review

    By Jim on 07/17/2010

    Verified Purchase

    Seems to be doing the job on black widows and scorpions. Strangely, more scorpions were seen indoors after first application but they were asking to be taken to the ER. Leaves a slight residue, which is the whole idea with the powder, but it's not objectionable and can be wiped/washed off if need be.

Q
I need to know how to use Cyper WP with Permethrin SFR for Wasps.

I need to kill wasps on my property, and I plan on using Permethrin SFR mixed with Cyper WP. When mixing these two products together, should I use the recommended amount for each product as if I was using each product alone? I need a quick knock down from the Permethrin, but I also want a good residual from the Cyper WP. What are your suggestions for the amount of each product per gallon of water in a tank sprayer? Thanks!

A
Permethrin SFR and Cyper WP are both very similar products, and we really do not think you should mix them together or need to. Cyper WP does have a slightly longer residual than Permethrin SFR, but it also has a fast knockdown just as good as the Permethrin SFR.  Typically, you would mix one ounce of Permethrin SFR with a gallon of water and one scoop of Cyper WP with a gallon of water (the Cyper WP comes with a scooper since it is a powder).

Q
What product do you recommend for spiders, earwigs and general pest control?

What product do you recommend for me? I live in New Orleans, LA. I am mainly dealing with spiders and earwigs. What do you recommend to treat my the perimeter of my home and foundation with? I'm looking for something with the longest residual, that could hold up against the hot, humid summer sun, as well as frequent rain. In addition, what lawn treatment do you recommend? Thank you.

A
Cyper WP can be used indoors and outdoors for spider, earwig and general pest control. Cyper Wp is a wettable powder formulation which stands up well to moisture, heat and sun. When treating indoors be sure that all pets and other people are out of the application area and they can return as soon as the area is dry. The Cyper WP product label recommends 2 scoops of product per gallon of water, sprayed directly into cracks and crevices, under appliances, around door frames and window frames and in places where utilities (cables, pipes, wires) enter into the structure. Outdoors you should spray around the bottom of the foundation, on the ground adjacent to the foundation, door frames, window frames and places where the utilities enter into the structure. Talstar PL Granules would be a great choice for insect control in lawns

Q
Demon Wp has worked well for me for 4yrs in S. FL. Your out so thought I'd try Cyper wp?

Wondering if the residual ingrd. that helps it stay outdoors is the same. Demon got rid of heavy roach ,spider infestation when I bought my home and has kept it away for 4yrs. I spray inside every 6mos and outside every 3. I did see today that your supposed to spray every month. My bad. I do mix it to the fullest 2 scoops per gallon and I empty a 2gallon sprayer each time around the house perimeter outside. I have a 1000 sq ft ranch home. I do the soffits and down 3ft and then the ground 3ft out and the bottom of the house 3ft up. Seems to be working hoping cyper will work as well?

A
Yes. Demon Wp 1lb jars have been discontinued. We recommend Cyper in its place. It is considered the "generic" of Demon and will do a fantastic job!

Q
What can I use to get rid of spiders indoor?

I use Cyper WP for outdoor use. We have some small black spiders. What is safe around people?

A

Cyper WP can be used indoors and outdoors for spider control. When treating indoors be sure that all pets and other people are out of the application area and they can return as soon as the area is dry. The Cyper WP product label recommends 2 scoops of product per gallon of water, sprayed directly into cracks and crevices, under appliances, around door frames and window frames and in places where utilities (cables, pipes, wires) enter into the structure. We have recently added a spider control kit to our website that includes Cyper WP, Cobweb Eliminator and glue boards. Using Cobweb eliminator will help discourage spiders from forming webs on the surfaces that have been sprayed and the glue boards will help trap wandering spiders and help monitor problem areas.
