Cynoff 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. Cynoff WP is diluted with water and applied with a gallon pump sprayer. After it dries, Cynoff WP continues to work for up to 3 months.
Cynoff WP Target Pests
A variety of crawling and flying pests including (but not limited to) ants, boxelder bugs, cockroaches, crickets, earwigs, spiders, and wasps
Cynoff WP (similar to Cyper 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 target pests. Cynoff WP has a residual of up to 3 months. 1x 1lb. container of Cynoff WP yields up to 48 gallons of finished product. NOTE: Cynoff WP is the exact same product as Demon WP, but less expensive.
Cynoff 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 Cynoff 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.
Cynoff 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.
Best applied with a 1 gallon sprayer. Apply to outside foundation and all entry points such as around windows, doors, cracks and crevices, etc. Cynoff 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 sprayer with one half of the desired volume of water, add Cynoff WP, and fill to desired volume. Close and shake before use in order to insure proper suspension of the wettable powder. Shake or re-agitate the sprayer before use if spraying is interrupted. Mix only the amount of solution needed for the application.
*Retreatment may be necessary to achieve and/or maintain control during periods of high pest pressure. Repeat application is necessary only if there are signs of renewed insect activity.
*Repeat application should be limited to no more than once per seven days.
Each 1 pound jar of Cynoff WP makes 24-48 gallons of finished solution.
Standard Application Dilution rates / Mixing Ratios for Cynoff 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 that receive more direct sunlight
*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
Cynoff WP is for use in the following areas:
Permitted areas of use include industrial buildings, houses, apartment buildings, laboratories, buses, greenhouses (noncommercial), and the nonfood/feed areas of stores, warehouses, vessels, railcars, trucks, trailers, aircraft (Do not use in aircraft cabins), schools, nursing homes, hospitals, restaurants, hotels, and food manufacturing, processing, and servicing establishments.

Use 1-2 scoops per gallon of water and apply with a hand pump sprayer. Cynoff WP insecticide may be used as a general spot, crack and crevice treatment in non-food areas. All areas where insects hide or through which insects may enter should be treated.
Cockroaches, Crickets, Firebrats, Silverfish, Spiders, and Ticks: Apply as a coarse, low pressure spray to areas where these pests hide, such as baseboards, corners, storage areas, closets, around water pipes, doors and windows, attics and eaves, behind and under refrigerators, cabinets, sinks, furnaces, and stoves, the underside of shelves, drawers and similar areas. Pay particular attention to cracks and crevices; also see OUTDOOR USE.
Ants: Apply to any trails, around doors and windows, and other places where ants may be found. Refer to BARRIER TREATMENT directions to prevent infestation; also see OUTDOOR USE.
Bees and Wasps: Application to nests should be made late in the evening when insects are at rest. Thoroughly spray nest and entrance and surrounding areas where insects alight; also see OUTDOOR USE.
Boxelder Bugs, Centipedes, Earwigs, Elm Leaf Beetles, Millipedes, Pillbugs, and Sowbugs: Apply around doors and windows and other places where these pests may be found or where they may enter premises. Spray baseboards, storage areas and other locations. Refer to BARRIER TREATMENT directions to prevent infestation; also see OUTDOOR USE.
Apply as a residual spray either by hand or power sprayer to surfaces of buildings, porches, screens, window frames, eaves, patios, residential lawns only such grass areas adjacent or around private homes, duplexes, townhouses, condominiums, house trailers, apartment complexes, carports, garages, fence lines, storage sheds, barns, and other residential and non-commercial structures, refuse dumps, garages and other areas where pests are found.
Barrier Treatments: To help prevent infestation of buildings, apply to a band of soil and vegetation 6 to 10 feet wide around and adjacent to the building. Also, treat the building foundation to a height of 2 to 3 feet where pests are active and may find entrance. Apply as a coarse spray to thoroughly and uniformly wet the band area, using 1 gallon of spray mix per 400 square feet.

Extra Tips for Using Cynoff WP
*Some settling may occur after tank mixing Cynoff 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.
*Cynoff 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 must agree , this is far better than calling a pest control company, and it works very well. Cynoff WP killed my roach problem and I have not seen any roaches in 5 months. I have seen plenty of dead ones that I can scoop up and throw away. If you have roaches or other bugs causing you problems this is THE BEST STUFF . It goes on wet and dries to a power that is hardly noticeable but the main thing is it is CHEAP and it will work, you will be happy. Don't call pest control until you try this first...it will save you lots of money.
I've used Cynoff WP as a drench for fire ants after opening the mound with rebar. I pour about a gallon down in the hole. The kill is almost instant! I also use it as an exterior spray every 3 months and it keeps out nearly all bugs! Thanks for making it available to the homeowner. I've recommended this product and your site to many friends and neighbors!
Cynoff WP works great for roaches inside and out. Warning, since it is powder based it leaves a milky white residue where sprayed. I will use something different for inside next time (liquid based and clear drying).
I was skeptical at first when my husband ordered because I never heard of the product (and thought was a little pricey) but it really works. We used it to eliminate wasps that build nests under our porches and siding, and were surprised to see the results. Spiders and other bugs were falling out, along with the wasps. We will definitely use this product again.
Yes. Unless other wise noted, the pesticides on our website are safe to use in a home with children. As with any product, it is important to follow the label instructions and precautions to ensure safety. Cynoff WP should be used as a crack and crevice treatment indoors.
Is there a product that does not leave a white residue? I have a dark house inside and out.
A comparable product to the Cynoff WP that will not leave a white powdery residue is Cy-Kick CS. Just like a wettable powder, 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.
I have been told that there's not a pesticide that will kill this type of scorpion, and Cynoff WP only kills off their food supply which will make them move. What product do you recommend if it isn't Cynoff WP?
Cynoff WP will kill scorpions, but scorpions do take longer to kill than other insects. Most insecticides must be ingested for them to work, but since scorpions do not groom themselves like other insects it takes longer for them to get a lethal dose. It is also true that Cynoff WP can help eliminate much of the scorpions food source (other insects), making your property poor hunting grounds and forcing the scorpions there to move and stopping new scorpions from moving.
Will Cynoff WP Get Rid Of Bees, Wasps, and Hornets on Wood sided barn?
My barn is 100 long by 60 feet wide with 14 foot walls. The siding is all wood and most of it is exposed at this time as the stain has worn off. This has provided excellent staging for bees, hornets and wasps. I intend to stain the entire barn, but I'd like to get rid of the stinging bugs first. Can I spray Cynoff WP on the entire exterior walls of the barn to effectively reduce the massive numbers of wasps, hornets and bees? If not this, what should I do?
Yes, Cynoff would be a great option for you. Bees and Wasps: Application to nests should be made late in the evening when insects are at rest. Please be aware that this product has the potential to leave a slight residue over dark areas.
I understand that it dries to a powdery film. Could this film transfer onto my cats feet and coat at all, to later be ingested?
Cynoff WP is safe to use around pets when used as directed on the product label. Cynoff WP is a crack and crevice treatment indoors and when used this way cats would have very minimal opportunity to contact the product. Also, once the product is applied there is only enough active ingredient to kill a tiny insect and not enough to have an effect on an animal as large as a cat.
