Does not work in the slightest! The roaches walk right over it as if it is water. I have sprayed twice in one week and they are still coming!! I purchased it after reading the amazing reviews and it is horrible, a can of black flag did better! I have watched them walk where I know I have sprayed and go on living happily ever after. It doesn't even deserve the 1 star but I had to give something. Guess I will try again with a different product as I have to get these things out of my house.
FenvaStar EcoCap is a residual and microencapsulated insecticide, therefore it will not provide an immediate knockdown of listed pests. Most over-the-counter products are intended to be quick-acting, but they offer no residual protection after they are dry. FenvaStar should not be applied more than once every 7 days.
We also recommend using a roach bait gel and Insect Growth Regulator for roach control, in addition to good sanitation and exclusion practices. See our Indoor Roach Control Guide for more information: http://www.domyownpestcontrol.com/indoor-roach-control-c-2_348.html
