Good stuff. Like the concentrate.
Would RecommendNeem oil does the trick on aphids and other pests. This is the first time I bought the concentrate - makes a lot of sense. I top is actually a measuring cup and works quite well. This small container will make GALLONS of spray for your pests. Highly recommend. And, it happened to be on sale the day I bought it.

Strong Horrible Smell
Would Not RecommendThis product has a strong horrible smell and almost killed my plants when I sprayed the soil. It works to kills gnats on contact but it is too strong. Use more water than product.
