    5 of 5 Stars   Kill is almost instant!
    March 20, 2007

    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!

    5 of 5 Stars   Warning does leave white residue.
    January 3, 2008

    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).

    5 of 5 Stars   The best stuff!
    February 19, 2006

    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.

    October 3, 2005

    Cluster flies and asian beetles. I used Cynoff last year and it worked just great. I used to have our house sprayed at a cost of over $225/year. Now I do the spraying myself and save a bundle.

    5 of 5 Stars   This Stuff is Fantastic; Works Great!

    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.

    I like mixing my own pest control solution and with Cynoff WP, the job is complete and very effective. I'll buy some more in the future when I run out of my current supply.

    5 of 5 Stars   Terrific product!
    April 20, 2006

    Absolutely terrific product. I purchased Cynoff WP to control spiders (I'm an arachnophobe) and the incessant wasp invasions. It seems to be doing the job quite well. I treated a couple of outbuildings and was pleasantly surprised to find it also solved another problem - carpenter bees. This is the first product I have found that has had any real effect on those beasts. I have an office in one of the buildings, and have experienced no odor or other problems. Very highly recommended!

    August 1, 2006

    Cynoff WP is the only thing I found to control flies. Works for spiders and a lot of other accompanied pests.

    4 of 5 Stars   Cynoff is Awesome
    April 14, 2011

    Sprayed 2 homes last weekend and as of today I haven't seen any pest which is great and consider the fact that we are having a major drought here. This product did not leave a white powdery residue, will use again

    5 of 5 Stars   Carpenter Bees are gone
    June 20, 2011

    My sister owns a log cabin and I went to her with my concerns of Carpenter Bees drilling through every thing on my back deck. She told me about Cynoff WP. The price was very reasonable as I had spent that much on things that didn't work.We sprayed the deck and then all around my house being I read how many bugs it did kill. I was very impressed there is no odor. I have lung issues and have to be careful.  I noticed within 2 days a no bug zone. We can now sit out on our back deck and not one bee, fly, wasp or any creeping crawling flying insect has been seen.  I then went to the basement and proceeded to do around windows, doors. and baseboards. I even sprayed where the spiders like to play. It is now 2 weeks and not one insect has been spotted. This stuff is the greatest!!  Now if you could find something that kills Poison Ivy we would be set for life :) I called and spoke with a representative and she walked me through all my questions. I can not thank you enough for helping me with the carpenter bee problem. The other insects gone were like a gift I did not expect. Thank you Do My Own Pest Control!!!

    Cynoff WP does exactly what it claims. My bug problem has been nonexistent since I first sprayed. The product was delivered quickly and I received it ahead of it's scheduled delivery date. I will definitely use this site and this product again.

    I have purchased this item last spring in hopes of killing hundreds of earwigs that just multiply every year.I have seen many dead ones around my house inside and out after using Cynoff WP and can say that I am winning the battle after years of disgust.I reordered more for the entire yard perimeter as it kills mosquitoes too.I can say this works as my earwig population has reduced tremendously this year with a few stragglers from last year that got away.It also kills other insects too! Great product and will continue to buy as needed.Thank you!

    5 of 5 Stars   Spray and Forget
    August 30, 2010

    I've been using Cynoff for 4 years now and find it's like having a headache and using Excedrin (you can't live without it). I HAD problems with yellow jackets building hives under my eves on my home in the fall. That was eliminated by using Cynoff. Ants were finding a way into the house also, but a quick trip around the house, spraying the foundation and about a foot of lawn in front of the foundation is all it took to halt that. Since I started using this miracle bug killer I haven't had one squeaking cricket sneak into the house, either. This product will be used by me forever. It's one of those rare products you can buy that actually WORKS. Buy some.

    We use Cynoff WP for cluster flies. It is the ONLY thing that has helped us in 8 years. It has reduced our flies by 95%.

    5 of 5 Stars   Great for scorpions
    October 1, 2012

    Since they took Dursban off the market this is the best product I have found to keep scorpions out of the house.
