3 of 3 people found this review helpful:    By D.J. from TX on 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 firends and neighbors! Was this review helpful to you?

2 of 2 people found this review helpful:    By Toby from Wisconsin on 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. Was this review helpful to you?

2 of 3 people found this review helpful:    By R Bruni from Birmingham, AL on 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). Was this review helpful to you?

By Tom from Marble, NC, USA on April 20, 2006 Absolutely terrific product. I purchased Cynoff WP to control spiders (I'm an arachniphobe) 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!

By Chris from Georgia on 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 noticable but the main thing is it is CHEAP and it will work , you Will be happy. Don't call the pest control until you try this first...it will save you lot's of money. Was this review helpful to you?
