What should I write great? There is very little powder in such a package, but it worked perfectly! The caterpillars I have before, so thoroughly it was hand collected. The powder I mixed as indicated on the package, and sprayed my boxwoods. A few days later, I still saw 3 black dried caterpillars, but then the nightmare was over. Since the end of May, the boxwoods crawler free and prosper again magnificently.
