For more than just roses

Sprayed this on my roses at dusk and all mites were gone by morning. I had borrowed my neighbors Bayer bottle first with little change a few days earlier. Prefer no chemicals anyway! I knew Neem oil deters other bugs too, so I sprayed it under all door sills and now no ants or spiders either. Excellent product!

Bought on sale towards the end of the growing season when I moved some outdoor plants into a 4 season sunroom. Spray took care of the little gnats and flies that followed plants inside with one application. Will buy again when needed

This stuff works great.. Just because it's cheap doesn't mean to pass by it on the isle... It killed on contact with the first treatment...
