Box elder bug problems
By Todd on April 12, 2010
Verified Purchase
I had a Box Elder bug problem for the last 20 years. I have used several different products out on the market and have not found anything that would work. Since I have bought Cynoff EC and applied it to the surrounding foundation of my house the bugs have not returned. I am very pleased with your product and would recommend Cynoff to anyone having the same issue I have had.

Great Product. Same as Pros use
By Lorraine on November 10, 2010 Verified Purchase
We priced a professional and they wanted $150 for the first treatment followed by $60 every two months. In addition, they wanted everybody and all pets removed for 4hrs when they came for the treatment. I checked and this is the stuff they use. Easy to mix and use, not nearly as harmful as many products, and it seems to work great! Don't waste your money on the "Pros" just "Do My Own Pest Control!"

Needed help with spiders and other crawling pests
By Annie on August 11, 2010 Verified Purchase
So far, since spraying a week ago, we are seeing fewer spider webs. There are crawling insects laying on their backs with feet in the air. It looks like we have a good product here. We mixed it according to directions on the label. I was so pleased that it did not leave a white residue on the paint, screens and windows. This bottle looks like it will last a long time.

Cynoff EC = Dead Spiders
By Paul on July 11, 2011 Verified Purchase
I have been fighting brown recluse spiders for almost two years. Most of my fight has been done by a "professional exterminator". After doing a lot of research on the brown recluse spider and pest control in general, I discovered that my exterminator was not using the best pesticide for spiders, he was not using an appropriate amount of pesticide and he was not applying the pesticide in a way that would create an effective bug-barrier. Prior to me taking on the spiders myself, the only dead spiders I found were in some of the 30+ glue traps that I have stationed around the inside of my home and in my garage. Since I have been doing my own pest control, the spider-count in the traps is down substantially and I am actually finding dead or dying spiders outside of the traps. Cynoff EC is a real killer. I use Cynoff EC inside my home because it is non-staining; I use Demon WP around the perimeter of my home and in the garage because it is a wettable powder and it has a little more staying power. Cynoff EC and Demon WP have the same active ingredients, but the Cynoff EC drys clear and the Demon WP leaves a visible residue on my wood floors. Both work very well against spiders.

Cynoff EC
By Craig on November 11, 2010 Verified Purchase
We've had a ladybug problem for 5 years and used Cynoff EC to take care of it. The spray was easy to apply, it didn't stain our house, and it was very effective. We sprayed a little over a week ago, and we continue to see new dead bugs. We are very happy with this product and plan to reapply if needed.

Cynoff EC
By Bunyan on May 17, 2013 Verified Purchase
Wasp and Mud daubers were ruining the walls and ceiling with nest building in my carport. I have been using Cynoff EC for at least ten years for the control of wasp and mud daubers inside my open carport. An application twice each year has done wonders. The wasps and mud daubers will fly around the wall and ceiling but will not light.

CYnoff EC
By Candy on June 3, 2012I live by myself and always thought of myself as a clean housekeeper. For some reason however, bugs decided to come and invade my house. Every morning, when I turned on the kitchen light the little critters would scurry for darkness. I bought this product, sprayed as directed. The first morning, there was a bug :(. The second morning there were 2 bugs, but they were legs up. For the following week, I might see a bug but it was dead. I have not seen anything for 3 weeks now and I could not be happier with my choice. The money spent was well worth it

Gets rid of stink bugs
By Brian on September 22, 2011Last year I had dozens of live stink bugs getting into my enclosed and heated porch. After I sprayed around the edges of all the sliding glass doors with 1 oz Cynoff to 1 gallon of water, I'd see a few dead ones a week. I've also used the same concentration for carpenter bees with good results.

QWill Cynoff EC leave a noticeable film on my dark siding?
I notice that several of the cypermethrin based products say they leave a powdery film on dark surfaces. I want to spray my dark gray siding where I have a massive stink bug infestation. Does this product leave a similar film?
ACynoff EC will not leave a white powdery residue on dark siding. The products that leave that white powdery residues are in fact wettable powders and all have the letters WP in the product name (Cynoff WP, Demon WP).

September 28, 2009Dorian asked:
QWill Cynoff EC kill a yellow jacket nest in the ground? If so, how should it be applied?
ACynoff EC will kill a yellow jacket nest in the ground. If you know where the entry point is then you should mix a gallon of product in a one gallon hand pump sprayer. Once you have a mixed a gallon worth of solution, remove the adjustable nozzle off of the end of the sprayer so the solution flows out of the wand of the sprayer quickly instead of spraying out of the nozzle slowly. You should place the nozzle in the exit/entry hole and flood the opening until the solution back flows out of the hole signaling you have filled the entire void in the ground. It is best to do this at night or early morning using a flashlight when all of the bees are in the ground and less active.

QWill Cynoff EC kill scorpions too?
ACynoff EC is not labeled for scorpions but it should still kill any scorpions that come into direct contact with treated surfaces. We do carry a Scorpion Control Kit which contains all of our top selling scorpion products.

QWill Cynoff EC kill Bed Bugs
My Exterminator has been using Cynoff EC to treat a an indoor bedbug and tick problem. I see that Cynoff EC kills ticks will it kill BB too?
ACynoff EC is not labeled for bedbugs so we cannot recommend you use it for bedbug control. We do have many products that are labeled for ticks and for bedbugs. Please refer to our Bedbug product page and our bedbug kits to see what we recommend to get rid of this pest.

QWhen spraying for normal indoor routine spraying what is the ratio of of Cynoff EC to water?
ACynoff EC can be used .5 - 1 ounce per gallon of water for indoor use. Use the higher rate for severe infestations and the lower rate for maintenance
June 18, 2010Jerry asked:
QHow long is the residual effect Cynoff EC expected to last?
Cynoff EC is a residual pest control product. When used indoors I would expect it to be effective longer than when used outdoors. I read that it should be applied every two weeks for proper control of fleas, but that seems like a very short residual effect. So, how frequently should I treat with Cynoff EC for control of ants, roaches and flies?
ACynoff EC can be expected to last up to 30 days outdoors and up to 60 days indoors. UV light and rain outside can deplete the residual outside, but UV light is the main culpret. If one side of your home is in direct sunlight all day, then you may only get 3 weeks out of the product. For fleas specifically it is a good idea to treat once and then again exactly two weeks later because fleas hatch every two weeks and your chances are better if the product is stronger than weaker. After the first two treatments you should be able to only apply every 30 to 60 days for maintenance control.
June 30, 2010Julia asked:
QIs Cynoff EC safe to use with a well on the property?
I just need to know that using this isn't going to hurt my well water. I also have horses and dogs on the property. What precautions should I use?
AAll people (except for the applicator) and animals need to be out of the area when Cynoff EC is being applied and they can return as soon as the area is dry. You should not treat closer than 15 ft to the well. Synthetic pyrethroids like Cynoff EC will not reconstitute once they are dry and are not known to move through the soil.
July 7, 2011Mart asked:
QIs Cynoff EC safe to use on vinyl siding?
Using the recommended application with a fogger and mixed with light mineral oil.
ACynoff EC mixed with oil can cause staining on older siding or siding that is in need of paint. Homes with newer siding or freshly painted siding should be fine. Just to be safe, you should always test small inconspicous areas to be sure staining will not occur.
May 1, 2012Greg from Ms asked:
QWhen spraying indoors Cyonff EC indoors, how long before it will be safe for indoor dogs to return?
ADogs can safely return to treated areas treated with Cynoff EC after the area is dry. Usually this will take about an hour.
September 28, 2012Kathy from Spring Texas asked:
QIs Cynoff EC safe to use around cat?
I have 2 young cats and a 15 yo cat. I don't want to spray anything around my house or front & back door that would hurt them. I have a problem with dirt daubers. They've nearly ruined the red brick around my front door.
ACynoff Ec is safe to use around most cats. Cats should be removed from the area during the treatment and they should be kept of the area until it has dried. Please read the Cynoff EC product label for the complete usage instructions.
