The description above says specifically for automatic misting systems. I bought it and used it for a year and had to replace 55 nozzles that clogged. Also, when I cleaned out the drum there was an oily residue on the bottom. I called and this information (for misting systems, mix with water) was confirmed. However, it contains petroleum, and the detailed five page label says for outdoor spot treatment only, to dilute with oil, and not to get on plants and anything that might stain. Save yourself grief and expense and use something else.
