Customers overwhelmingly praise this natural concentrate for its exceptional effectiveness against aphids, whiteflies, gnats, spider mites, and powdery mildew. Reviewers consistently highlight the organic, non-toxic formula as a safer alternative to synthetic pesticides, valuing its safety for vegetables, pets, and the environment. Many appreciate the concentrate format, noting that a little goes a long way and makes up to 20 gallons of solution, offering excellent value. Users find it easy to mix and apply with standard sprayers. A few mention the strong odor and note limited effectiveness against Japanese beetles, requiring repeated applications on some pests. Overall, most customers consider it an essential, highly effective solution for organic gardening.

Works for Aphids but

Would Recommend

Gets rid of aphids but they will come back. Does not have a horrible smell, maybe only for sensitive noses, doesn’t compare to fish fertilizer smell which is horrific.

Works if reapplied often enough

Would Recommend

This product worked for me as advertised, it kept the Japanese beetles off the plants I sprayed quite well, but also as advertised, it needed to be reapplied after @ 5 days. In the past, I used Sevin spray, which worked really well for much longer, but The Neem oil is better for the environment so that's a choice I made.

Would Recommend

A good alternative to toxic chemicals. The downside is that repeated applications are necessary. however, considering the health of my family this is a small price to pay. The directions are straightforward, but there are several pages that are attached to the bottle that is cumbersome. However, it is good to have them accessible rather than having to run to a computer to look them up on a website.
