Some say white others say mild amber which is best?
According to the MSDS sheet for the Hi-Yield 38-Plus Insect Control - 38% Permethrin the product is a light amber in color. We have spoken with the manufacturer and last year they did change their formula to a water based solution that makes the product more gentle on plants, less odor, and is now a milky white color.
