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.
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.

Extra Tips for Using Cyper WP
Some settling may occur after tank mixing Cyper WP. Be sure to agitate the tank after resting, and only mix the amount of product you intend to use within 24 hours.
Store concentrate out of direct sunlight and extreme temperatures for maximum shelf life of 3+ years.
Not labeled for use on edible plants
Exposure to direct sunlight will break down residual more quickly, so applications may need to be made more frequently in these areas.
Cyper WP is not suitable as a space spray with equipment such as misters, foggers, or aerosol equipment. The product will clog or damage the equipment and is not labeled for this use.
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.
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.
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.
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.
Can you please explain the difference between Demon WP and Cyper WP?
There 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.
How 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.
Is 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.
I have spiders in and on my house. Which product is better for killing them, Cyper WP or Demon WP?
Cyper 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.
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.
