Cyper WP (Discontinued)

Walt Cline - Pest Control Professional Pro Tip: "The 1 lb bulk form of Cyper WP is now discontinued. We continue to have the Cyper WSP (water soluble packets) in envelopes and the Cyper WSP in a larger container is coming soon. Cyper WP is a great product to use outside for the large roaches. Cyper WP, like other cypermethrin products does not control indoor German roaches well. Since Cyper WP is a powder that mixes with water, it tends to leave a film residue that can be seen. If you need to treat inside, you might consider Optimate CS as a good alternative."

great product
We used inside for german roaches. worked great. Why not selling anymore? Loved this product. It did leave a little residue but killed the bugs. Liked the residue better than the bugs.

Its a bug terminator
I have used it for 4 yrs and my house is the only one on the block with no bugs. No scorpions, no roaches, no spiders, no ants, one tarantula got close but died also. I use it with a backpack sprayer and protect my entire yard on 3 gallons every 3 months. My neighbors pay an exterminator $ 30 every month and still have bugs. I use a 1 lb can every 2 yrs. That's less than $ 2.70 per month over 4 yrs including the cost of the backpack sprayer.

Excellent product
This is my second Cyper product as I was using Cyper LO before. I have had excellent results with both products. I have noticed that here in Louisiana I have to reapply about every two weeks to keep the paperwasps from coming back. The only product I have found that gets rid of them though. I love it.
Review by Victoria / (Posted on 7/29/2014)
Great to MIX
just added some to my mix with Equil Lambda and Bifen and I don't have any more insects or any creatures. And my DOGS love that no more fleas and ticks. I did have to keep them away from the area but they were fine after 4 hours of the poison being placed.
Review by Ben / (Posted on 7/18/2014)
Finally found a product to kill the scorpions in the house
and garage. Have used this for 2 - 3 years and it is extremely rare to see a bug in the house. The insects in the garage are all dead. Told 2 friends about it and they love it, too. So nice to find a product that works so well. Am about to order our 3rd Cyper WP.

Sprayed inside, now no more black ants. Sprayed in garage, no more spider. Im now 1 happy camper. recommended Cyper WP to my friend, expect order from them soon...
Review by Le / (Posted on 7/11/2014)
Worked for me
I had an annoying aggregation of sun-bathing box elder bugs. One application did the trick. They either died or they're sunning themselves at the neighbor's house. I've noticed other pests moved along with them. I'll continue to use the product on a regular basis from now on.
Review by Noah Mobugs / (Posted on 7/2/2014)
Did not help for flies around the barn
I bot this as recommended on the DIY website and applied as instructed. I have re-applied and seen lots of flies sitting on treated areas. I even sprayed manure piles that were covered with flies, but noticed no decrease in numbers.

Cyper WP works
I have been using Cyper WP for two years and have had amazing results. I live on a lake and had been fighting roaches, palmetto bugs and spiders for years. A good many products work moderately well, but Cyper solved my problem. I use a tank sprayer on my ATV and spray the entire outside of my house up about 3 feet and around all the first floor windows each spring. My house is vinyl covered and that made control of spiders a never ending task. Cyper solved this problem with 1 spraying a year.

Best Product

Review by Gary / (Posted on 5/20/2014)
tremendous product
Used this product years ago when daughter had an overwhelming infestation of Yellow Jackets. Found a nest size of TWO pillows in rafters. Were traveling throughout house in heater ducts and air conditioning. This product saved the day!!

Will be using it again as wasps are invading again, but not for long...

Cyper WP
I live in Arizona were we have issues with scorpions. Started using this product two years ago and have not seen one scorpion on our property.

As for all the other bugs we have here, they have been eliminated as well.

Great product if you don't like creepy crawlers.
Review by Bob / (Posted on 5/13/2014)

One reviewer complained it did not work on German cockroaches but it kills vermin from Somalia,Nigeria,Cambodia,Thailand, Haiti and Mexico etc. in a high rise.

I have been well pleased with this product so far . I sprayed once about a month ago and have not seen any bugs . I am very well pleased .

Cyper WP does the job.
Inside and out, the only product we use for virtually all pest control.
Fleas, roaches and pillbugs all disappear. I also use to spray fireants mounds and it seems to be effective there as well.
Highly recommend this product AND DIY pest control service.
Review by Avcad59 / (Posted on 4/30/2014)
Best pest control product ever
I'm on my second order of Cyper and it is definitely worth every penny. Great company, my order came within three days and to top it it shipped free.

Only thing to buy. Only place to buy it

I have been using this product for several years. I use it around the outside of my home, and it controls pests very well.
Review by Jt / (Posted on 4/17/2014)
Great Product
Superior performance for fleas, roaches etc. ; we used extensively in rental houses where pets had been and fleas etc were Totally out of control. Used high concentration to knock down and returned to saturate area. Product completely removed all pests. Could not be happier with performance.
Review by Avcad / (Posted on 4/9/2014)
Have used this product before
I have used this product before for years. I continue to acquire because it works for me. Kills lots of bugs around my house.

Prompt delivery by Do-it-Yourself was great.
Review by pacaarmijo / (Posted on 3/25/2014)
Great product
I have been purchasing Cyper WP for many years. Works better than any other product I have used. Can be applied indoors or outdoors. No odor and very little residue. If want a insect free home this is the product.
Review by Skillet / (Posted on 3/22/2014)
Best all-around pesticide out there
The price and quality cannot be beat. I HATE spiders. I hated even having to type that word. After many hours of research and a lot of trial and error and wasted time and money, I have finally found the best product to solve my problem. No more you-know-whats. This coupled with D-Fense Dust has me completely happy. No more, uh, bugs!
Review by Marty / (Posted on 3/14/2014)
I live in Arizona and have a HUGE scorpion problem. This stuff kills those nasty things. Love this product and use it every year during the summer when scorpions are everywhere.
Review by Sharon / (Posted on 3/9/2014)
Excellent Product
I've been using this product for years - tried a few others, but I stick with Cyper WP now. Effectively kills everything claimed on the label and more. I have recommended this product to everyone. I sprayed my storage basement down a year ago and this stuff is still working down there! Amazing.
Review by Karen / (Posted on 11/22/2013)
Works great
Have used indoors discreetly and outdoors...always works all kinds of insects. From the large "water bugs" roaches that exit sewer system to ants seeking refuge inside. Great product.
Review by Joe Peshi / (Posted on 10/31/2013)
Demon Killer
Kills all the Demons it comes in contact with and those that try to crawl through the residue. It's 1/2 the cost of Demon and easier to use and store. Will definitely continue to use and will reorder along with several other high quality/value products.

Hot Stuff!!
This product WORKS!!! OMG!!! It's like a Bug BarB-Q!!! I love it!
Review by SunshinePC / (Posted on 10/29/2013)
Great product
Wife went thru several pest control services and thousands of dollars and was still not completely satisfied with any of them. I told her that I would take care of it. I ordered a sprayer and Cyper WP. That was several years ago and I have not heard one thing from her (at least about insects). I spray twice a year and highly recommend this product.
Review by GK / (Posted on 10/26/2013)
It works
I live on a lake and use pine straw mulch. This translates to a bumper crop of palmetto bugs and roaches. I purchased the Cyper WP on the recommendation of an exterminator. I used a 12 gallon tank with 12V electric pump to treat around my house and all outbuildings. I could not believe the number of palmetto bugs and roaches that it killed the very first night. I used the boric acid dust inside the house. I saw my first palmetto bug last night and it has been about 2 months. I plan to use the Cyper WP again in about 2 months and will purchase the Cyper WP as an inside treatment. Very good product.
Review by Larry / (Posted on 10/24/2013)
not effective
Based on the reviews, I thought I would get rid of roaches immediately. Three weeks later, still lots of roaches. I even put 4x amount and did not see any difference. I mixed a solution of bleach and water and had better results. Suspect the powder was not the real stuff. It didn't come with required MSDA sheet. Order again? NO

DIY RESPONSE: Sorry to hear you had issues with the product. Cyper WP is not recommended for German Roaches, but is effective against "water bugs". For German roaches we recommend roach baits as the best treatment option. All material safety data sheets are available on our website. They are found at the bottom of each product page.
Review by dw / (Posted on 10/24/2013)
Excellent product
I have a large yard with many trees and bushes. We use leaves and pine straw as mulch around plants. Asian roaches thrive in this mulch. Thousands of them. We also have millions of what we call sugar ants. I don't have problems with fire ants since these sugar ants came in, so I don't know how effective this product is on fire ants. I use a 25 gallon pull-behind electric sprayer and mix Cyper WP at 2 scoops per gallon and spray around all my bushes and around all buildings from the ground up to about 3 feet up the walls on the outside. I even spray up the trunks of trees about 3 feet. I spray the floors of my garage and outbuilding. I have checked these places for 2 weeks and have only seen a stray ant occasionally. It does the job.

Works great for boxelder bugs
This worked very well to kill boxelder bugs and is cheaper than some of the other products I've tried in the past. It not only knocks down the bugs that are present but continues working for a day or two as evidenced by the dead bugs laying around.

The downside is that it does leave a milky kind of residue on windows or anything dark. Personally, I'll take the over-spray instead of the bugs.

Definitely will buy again!

Wiped out Ants in Southern Calif.
Had thousands of small ants. This product killed the ants and stopped new ones from returning for about 5 months. I retreated and got the same results. Great product.

Scorpians Beware..... and all you other little buggers
I live in Southeastern Arizona. Been using this product for 6 months and have not had one living bug on the property. Fantastic product. Told two of my friends about using this product and doing your own pest control. They started using it and dropped their pest control service as well.

It will save you on average about $400.00 a year doing your own pest control. It's easy and you know it works!!!!!!!.

great for roaches and spiders
Was a pest control person for 13 years this is same as we used it is 1 of the best for roaches and spiders kills fast lasts very little smell can't go wrong with this great price as well nothing you will find at chain stores will come close
Review by jrose / (Posted on 5/10/2013)
I tell everyone about this
I bought this early last year, mostly for the spiders and centipedes we get in our house. However, we also have minor termite problems, carpenter bees, ants, mosquitoes, ticks, stink bugs, etc. This kills them all. One container lasted the entire year last year, even though it had been a particularly long pest season. I'm ordering again for this season, and I wouldn't consider any other product. When my neighbors, family, and friends complain about their seasonal pest problems, all I say is "Cyper WP" and send them this link.

Stink Bug Killer
I just got on line to place another order for this stuff! Folks, this stuff is the best for killing ALL bugs outside here in Wv. I spray all around the house and buildings to keep bugs out, then when the sting bugs get ready to swarm, I spray from top to bottom and continue to find PILES of dead bugs on my porch weeks after I have sprayed. Can't go wrong with this stuff.

Live in rural area outside Phoenix prone to scorpians this is all i use and it leaves death in its tracks......
Review by daveymack / (Posted on 9/22/2012)
Best stuff ever! Had roaches in and around my yard and patio. Started using this about 2 years ago. Complete clean out! I continue to spray twice a year or so and I usually spray at dusk or in the evening when bugs are most active in order to make sure I get the black widows as well. Highly recommend!

Good for Scorpions in Texas
I used this inside and outside primarily for control of scorpions after we constructed a new house. Scorpions everywhere... It kills them adequately, but we have lots of dark trim inside and out, and as warned by the site here it does leave some visible residue. So, I am now using this as a perimeter treatment outside (it's cheap), but switched to Cyonara for the inside, also a great product.

Oh, as a side benefit, killed all the spiders and even wasps after we sprayed it during construction. Went from creepy crawly insects all over the place to a total dead zone in a matter of hours.

Great Product for Fire Ants
I have been using Cyper for years. I actually darn near cleared 30 acres of fire ants. Using a hand held pump sprayer I spent a day spraying fire ant mounds. The next day there were hundreds of thousands of dead fire ants. Two weeks later I went around to the same mounds and found tiny new hatched ants. Sprayed mounds again and pretty much eradicated all ants for the rest of the long Mississippi summer.
Review by Ward / (Posted on 5/29/2012)
Superior Product
I’ve been using Cyper WP for years to treat my house, barn and garage for insect control. Applied quarterly, Cyper controls all bugs and spiders I know of. Cyper does not quickly kill wasp, mud dobbers and hornets but it will keep wasp, mud dobbers and hornets from building nests on treated surfaces. Directions state to control Carpenter Bees to apply Cyper full strength powder in bee holes with a ‘powder puffer’ bulb. Treatment like this does kill Carpenter Bees. Excellent Product!
Review by Ward / (Posted on 5/29/2012)
Cyper WP
Ordering again after finally using all of my first purchases over 2 years ago. This is the only product I've found that really controlled our huge scorpion and red WASP problems .We have 5 acres with 2 barns and 2 storage buildings that Wasp and scorpions love. So glad i found this stuff. Same active ingredient as Demon but near half the price, can't beat that.
Just be sure to spray early early in the morning for wasp when they are less active; it's not a knockdown spray but it will kill them or run them off. On some tough next sites i had to reapply a few times to get them to disappear but eventually they did and i had my yard back.
Review by Scott / (Posted on 5/28/2012)
roaahes, ants, wasps no more!!!!
We've been using the cyper for the past 4 years. it takes care of our biggest problems roaches, ants, and wasps. i have children with asthma so roaches arent even allowed to be moving NEAR my home let alone inside it. We treat the inside of the house once a year, and treat the outside every month or so in the summer and ever couple of months in the winter. I have found I only need to spray the eaves and wasp nesting areas once a year. the residual is FANTASTIC.
