Product Documents

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%

Cyper WP Application Instructions

Cyper WP is best applied with a 1 gallon sprayer. Apply to outside foundation and all entry points such as around windows, doors, cracks and crevices, etc. Cyper WP is very toxic to fish. Do not apply near bodies of water or where there may be water run-off. Always read the label completely before use.

Fill applicator tank with the desired volume of water and add Surrender brand Cyper WP Insecticide. Close and agitate before use in order to ensure proper use suspension of the wettable powder. Shake and reagitate application equipment before use if application is interrupted. Make up only amount of treatment volume as required. Do not store dilution in application equipment overnight.

Cyper WP will continue to work for 90 days indoors and 30 days outdoors. We recommend waiting at least 7 days between applications.

Each 1 pound jar of Cyper WP makes 24-48 gallons of finished solution.

Standard Application Dilution rates / Mixing Ratios for CYPER WP:

*1 scoop (0.33 oz.)/gal. of water – 0.1% – maintenance, more frequent applications, foliar applications

* 2 scoops (0.66 oz.)/gal. of water – 0.2% -- clean-out, severe infestations, exterior applications which receive greater direct sunlight, scorpions

*For Perimeter Barrier Applications around Structures – Mix 1-2 scoops of Cyper WP in 1-5 gallons of water to cover 800-1600 square feet. Higher volumes may be needed for dense vegetation or landscaping materials.

*1 scoop is the equivalent of 0.33 oz., 9.5 gm., or 2 level tablespoons

  • Store concentrate out of direct sunlight and extreme temperatures for maximum shelf life of 3+ years.
  • Not labeled for use on edible plants

    4 of 5 stars  Very effective
    By Pam in Latonia,KY 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.

    5 of 5 stars  Cyper WP Works Great
    By Jim in Victoria Tx 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.

    5 of 5 stars  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.

    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.

    By Jim in Utah 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.

    By Becky in Florida on 02/16/2015

    This was my second purchase of Cyper WP. I always have used Demon but can no longer get it so Cyper was recommended. I do believe it works just as well as the Demon. I took away a star because I don't care for the white residue it leaves. I'll continue to use it because I live in South Florida and you have to stay ahead of the bugs, so the residue is really a pretty small price to pay.

    Sprayed 4 gals of this around the perimeter, porches, garage, and shop, just about a week ago. It knocked down a bunch of spiders and a few roaches so far. Very straightforward to mix and spray. We'll see how long before it needs to be reapplied.

  • 5 of 5 stars  Kill the little buggers!
    By K. in SE Texas on 01/04/2015

    I had used the "Malevolent Spirit" branded cyperethrin for a couple of years, with great results, but they no longer package a 1 pound package. I use this with a sprayer on the end of my water hose, and need to mix it strong to get the proper concentration. This one pound tub is perfect for my purposes, and it costs less than the other brand! It will kill nearly any bug, yet is safe for pets once it is dry.

    By Trudy in Vicksburg on 12/04/2014

    There were no instructions with the product as to how to mix it. Also, the container was only filled about half way. We have only used it once, but we do think we will like the product. A friend of ours, who uses the product, told us how to mix it, and I am sure once we get it mixed correct, it should work and get rid of our roaches.

    Expert Response   Expert response:
    The product label for Cyper WP is a booklet that needs to be peeled open from the label. You can also view the product label on our website anytime here: Because the product is a solid, it is packaged by weight rather than volume, so the powder will settle after packing and will not fill the container completely.

QCan you please explain the difference between Demon WP and Cyper WP?

AThere is no difference between Cyper WP and Demon WP other than the fact that Cyper WP is half the price for the same size as Demon WP.  They both contain the same active ingredient and perform the same.  Demon WP is the name brand, the first one made, by Syngenta.  Cyper WP is a generic version made by a different company called Control Solutions.  Just like there are about 10 different brands of aspirin at the grocery store that all do the same thing, pest control products are the same way and there can be multiple manufacturers that essentially make the same product.

QHow many scoops of Cyper WP should be mixed per gallon of water?
Hi. This is my first time using Cyper WP and I have the one pound container. It came with a scooper, but the package does not state anywhere on how much to use. I am guessing that it is one scoop per gallon. But I do NOT want to guess, so that is why I am asking you how many scoops per gallon?


Each jar of Cyper WP comes with a full product label attached to the the jar. If you take a close look, you will see that you can peel off the label and there is a direction booklet attached. Cyper WP does come with a scooper and you do use one or two level scoops per gallon. Most of the common pests require 1 scoop per gallon of water. If you are treating carpenter ants, carpenter bees, cockroaches, fire ants, scorpions, spiders, ticks or wasps, then you need to use 2 scoops per gallon of water.

QIs Cyper WP safe to use on a lawn with pets and dogs?
I want to use Cyper WP due to having a lot of spiders at my house. We have found brown widows with their "spikey" eggs. We also have black widows and common house spiders. We have 2 dogs that stay outside and are known to lick, chew and dig in most places. Is it safe to apply Cyper WP in the backyard where the dogs are if I let it dry before putting the dogs back out?


Yes, Cyper WP is perfectly safe to apply around pets and/or children.† When you are applying the product you should do exactly as you suggest, which is keep the pets inside or if applying inside in another room until the product dries.† After it dries which is usually about 30 minutes, it is perfectly safe to allow pets entry back into the yard or living space.

QI have spiders in and on my house. Which product is better for killing them, Cyper WP or Demon WP?

ACyper WP is the generic of Demon WP. Both products contain the same active ingredient in the same concentration. Cypermethrin, the active ingredient in both Cyper WP and Demon WP, is known to be one of the most effective active ingredients for spiders and other hard to kill insects. You might also want to check out our spider control kit, which comes with all the products you need to effectively control spiders.

QWill Cyper WP kill crazy raspberry ants?


Cyper WP will kill any type of ant that you physically spray it on, but the problem with most ants is that the colony is somewhere else.† If you want to get rid of the problem for good you have to get rid of the colony, which is the source of the issue.† We sell a Raspberry/ Caribbean Crazy Ant Kit that has been very popular for these crazy raspberry ants and it includes Termidor SC.† Termidor SC does not kill the ants right away, but it allows them to walk over the barrier you apply around your home, and the ants end up taking the product back to the colony where it spreads like a plague.† It works like a liquid bait.† Residents of Texas have been very successful with this product.

QDoes the Cyper WP kill fleas?
Inside and outside? Is it safe for pets?


Yes, Cyper WP is labeled to kill fleas and it's safe to use inside and outside. It can only be used on baseboards, cracks and crevices inside your home. The 1 lb jar has been discontinued though but we do have Cyper WSP or Demon WP available, these products are also safe on pets.

I would, however, recommend our Outdoor/Indoor Flea kit. You can use both, Onslaught insecticide and Martins IGR, in broadcast applications inside and out. Meaning you can use it on your carpet as well for a more thorough treatment. Both products are also safe for everyone as long as you follow the label instructions and let the area being treated completely dry before letting everyone come back into that area, including your pets.

QAny version that works longer than 30 days for Carpenter Bees?


We recommend looking at one of our Carpenter Bee Kits for a complete treatment program for Carpenter Bees. Most insecticides used outdoors will only have around a 30 day residual. Please read the information below for guidelines on how to do treat thoroughly for this pest.

Getting Rid of Carpenter Bees

Carpenter bees nest in wood; they do not eat it like termites. Before treating, make sure you have located all entry points of the bees, which look like perfectly round ½ inch holes. We sell all the products mentioned below, and all are included in our carpenter bee kits.

  • There will be male carpenter bees hovering around the openings. The male bees do not have stingers but may act aggressively and startle passersby. You can choose to use a knockdown aerosol to eliminate these bees or just swat them away. Females are equipped with stingers but rarely sting. 
  • An insecticide dust is the key product you will use to kill carpenter bees. A dust product like D-Fense Dust is perfect for the small holes that lead to the bee’s chambers. The bees will have to pass through the openings and will come in contact with the dust. Using a hand duster will ensure the dust can coat the tunnel surfaces and reach deep into the tunnels. There may be many entry holes and it is important to treat them all.
  • After you have treated the entry holes, the holes need to be plugged. However, you should not plug these holes while the bees are inside; they are likely to chew their way out. The larvae hatch and emerge in the spring – when you are most likely to notice them- so treat when you see them and notice the holes. Treat again in the summer and once more in early fall, before the bees return to their chambers to overwinter. It is very important to plug the holes because carpenter bees will return to their old nests every year. Use plastic or wooden plugs or putty and always finish the wood with varnish, sealant, or paint to further deter the bees.
