I have used this product for years and have never had any issue with it doing a good job. My complaint is with the wand. I have the new battery type wand and this is my third unit that has had a bad wand. It works for a couple of months then quits. I have changed batteries and it is still dead. I am getting ready to just start putting it in pressure tanks and spraying from there. The wand needs to be researched and determine why they are not lasting long. The only pull handle worked better than this new design.
I used this product for the first time in my house after seeing an increase in Palmetto bugs. We used to use Arrow peat control who came in to spray our floorboards, but since switching to another provider we have seen this issue progressively worsen. I've sprayed this product two nights ago now, and have seen a few bugs dead by our baseboards for the past two mornings. So glad I went with this solution. I'll be spraying the external now, and am hoping this works for the 12 months as advertised.
