What Customers Are Saying

The neem oil-based product is an effective and versatile organic pest control solution. It successfully repels and eliminates a wide range of pests, including insects, mites, and fungus, on both indoor and outdoor plants. The formula is praised for being safe and gentle, without harming plants or the environment. For best results, it should be used proactively and consistently, though some customers noted it may need reapplication after heavy rain. While a few experienced issues with effectiveness or plant damage, the majority of customers are very satisfied with the product's performance.

Lumpy Product

Would Recommend

I'm guessing this product is lumpy because of the chemical make up. It's my last hope at eradicating the white flies that have begun to destroy my Crepe Myrtle.
