Directions for CYNOFF WP Use

Cynoff WP must be diluted in water for spray or brushing applications. The product comes with a plastic scoop with 0.33 oz. capacity. Use a full scoop of Cynoff WP per gallon of water to yield a solution having 0.1% of the active ingredient. Doubling the amount of the concentrate yields solutions with 0.2% active ingredient content. Depending on the target pest/s, solutions must have 0.1% to 0.2% active ingredient content.

Apply the product as a coarse, low pressure spray to infested areas and potential insect-harboring sites such as basements, attics, behind and under appliances, storage areas, cabinets, shelves, baseboards, under sinks and along plumbing. Pay particular attention to cracks, crevices and voids.

Using hand or power sprayers, apply the product by brush or residual spray to building surfaces, porches, window screens, patios, lawns and other grass areas to control outdoor insects.

For barrier treatments, create a band measuring 6 to 10 feet around structures to protect them from infestations. Apply the product as a coarse spray, at the rate of 1 gallon per 400 square feet. Also treat building foundations and other potential entry points to a height of 3 to 5 feet.

Seems to be very effective, sprayed the perimeter of the house two weeks ago, greatly decreased the bug popultaion and i never see any where I sprayed.

I have spider-phobia. And from god knows where, my basement was full of spider webs and big spiders were all over the place. I had gone to the market and the market attendee there heard the problem and suggested the Cynoff. You have to dilute it to water for it to work, but man, this thing works wonder.

I am an accountant. I am quite busy and I even have to work extra hours on the weekends. It is quite difficult for me to find time for my family. My wife is very helpful but she is afraid of pests and wanted me to give the treatment. A colleague of mine recommended me to use Cynoff WP as she had used it herself and found it quite effective. I mixed it to be strong as I didn’t want to give a treatment more than once in a month. But that was more than two and a half months ago and there hasn’t been any pest infestation in my home since then.

My garden seems to attract a lot of different pests frequently. I am almost always busy with my garden and applying pest control products took a lot of time. I wanted a product which would have residual effects lasting a month or two at least. But, fortunately, I got Cynoff WP Insecticide which has a residual effect of three months. If you hate pests as much as I do, then Cynoff WP Insecticide iis your product.

The residual effects are also very good as I had given the last treatment a month ago and the effects still haven’t worn off.

5 of 5 Stars! (5/5)    Review by   Mark Cunningham  (Posted on )

It is really hard to apply the pest control products in the cracks, crevices and holes of the house and a trouble. If it was once a month it wouldn’t be a problem. One of the prime reasons for me choosing Cynoff WP Insecticidewas its great residual effect. I had an ant infestation in the cracks, crevices and holes of my house. Cynoff WP Insecticide is a very useful weapon in killing ants since it reaches the cracks, crevices, holes and corners of the house easily. I am really glad I chose Cyndff WP Insecticide .

Always will I buy professional pest control products from pest mall. I was just SO AMAZED by the professional resultsOf the Cynoff WP! Plus, it felt rewarding knowing that I saved SO MUCH money from doing it myself instead of calling a pest control servic.e this time! Pest mall does a great job making sure you get the package safely AND the best price.

I live in an area full of mosquitoes. No matter what I did the mosquitoes would not go away. It got to the point that I would close all the windows and doors of my house and my house started getting a damp smell. I ordered Cynoff WP Insecticide - 1 Lb and it was delivered to me two days later. Then I mixed it that day, itself and applied it around the porch, and the outer walls of the house. I applied it two weeks ago, and the mosquitoes are still not coming to my house!

pesticide for cockroaches
My house is near to the forest and it mostly has wooden furniture. So, roach,ants and spiders have been bugging us, since we had used the CYNOFF WP. It was very effective

5 of 5 Stars! (5/5)    Review by   Troy Benton  (Posted on )

I love the fact that Cynoff WP Insecticide doesn’t leave stains or smell behind. It leaves a strong residual effect that ensures no new insect entry in the structure for three long months. I used Cynoff WP Insecticide to kill carpenter bees. It took about 5-6 hours for the first bee to infect all the others and die but in the end it was worth it. Cynoff WP Insecticide is the perfect product in my eyes.

I am thoroughly disgusted by stink bugs. But there seems to be a great deal of stink bugs in my garden. I wanted a product which would get me rid of the stink bugs but wouldn’t leave a horrible stench behind on my flowers. Cynoff WP Insecticide is an insecticide which kills your pests in a few hours time. When it killed the infestation I was really happy. I thought that its effects would end in a week or two but it, surprisingly, lasted me three months which saved me a lot of money.

I am a high school teacher. I don’t have a lot of time and need to take care of the house as well as do my job well. My friends and even my family are amazed that I am a high school teacher and still get time to do all the house hold works, keep the house clean and bug proof. I would like to thank Cynoff WP Insecticide for doing such a quick and good job that leaves such strong residual effects but not a smell!

cypermethrin insecticide
I am very happy with Cynoff WP Insecticide performance so far.

5 of 5 Stars! (5/5)    Review by   Catherine Sherrill  (Posted on )

buy cypermethrin
I had a severe ant infestation in my kitchen. My kids would spill sweet stuff all over the house and so the ants are always attracted here. I bought Cynoff WP so that the ants would be killed and wouldn’t come here anymore. And I was right in buying Cynoff WP Insecticide - 1 Lb as it solved my ant problem in just one day.

CYNOFF WP will work better than you think. But just make sure not to get it near your food areas because that'll only make things more complicated. They shipped the CYNOFF WP pretty fast for me. I hope people will get the same great experience I did with killing pillbugs with the CYNOFF WP

It's been two months and there are no signs of ant infestations in my home. I will be so happy if the CYNOFF WP lasts another month! CYNOFF WP works really well! I have been sleeping so well in my own home now that there are no more ants crawling on my bed!

I’ve had a spider problem for as long as I can remember. It’s one of the charms of living in the country I suppose. I used to use a different product but I couldn’t stand the smell. This CYNOFF dust was easy to mix and has provided lasting protection without the awful smell.

We had a wasp’s nest near the back of our property. It wasn’t really much of a problem until my daughter had a bunch of friends over and one of them got stung. My husband is the pest control guy in our house so he decided on the CYNOFF powder which he mixed up himself. He attacked the nest in the early evening and we managed to clear them all out before the sun went down. This stuff is perfect.

I’m a real estate agent and I was recently assigned a new property. It was overrun with roaches and we didn’t have room in the budget for an exterminator. My boss purchased the CYNOFF and had one of his handymen mix it and apply it. It cleared out the roaches and they haven’t returned. I even managed to sell the house a few weeks later, my boss and I are both very happy with this product.

Is this product recomended for control of box elder and ladybug type bettles
A.   Boxelder bugs are on CYNOFF WP label as a target pest but ladybugs or Asian beetles are not on the product label as a target pest. Unfortunately, we do not have any WP formulations that have ladybugs on the product label as a target pest. However, we do have several liquid concentrates that are just as effective. Suspend SC and Talstar both will be effective against boxelder bugs as well as ladybugs.
