I've used another neem oil before and boyyy did that thang stunk. Made my whole living room smell like buttcheeks and sour eggs for a week. This Green Alcove variation did not have that funky odor and was herbal, floral, and pleasant thanks to the peppermint and lavender (didn't notice rosemary much). The included bottle is sturdy plastic and instructions are clear. I mix with 16 oz of water (plastic water bottle amount) and the sprayer works to spray fine mist. I lay a blanket on the floor since the product drips down and don't want my vinyl floor wet.
Ever since the summer began, I've started to see small annoying fungus gnats flying around my desk. That's why I don't leave out a cup of tea or orange juice since those buggers always take a bath in it. But, it's probably my own fault for not completely draining my plants after I bottom feed. They're so big and heavy and a little plant lady could only do so much when her husband's not around. So those moist standing water is probably what attracted them in the first place (promise I'll do better)!
I used this neem oil mixture on all my plants for about 4 days now and I haven't been seeing any fungus gnats. Now, I also have yellow sticky traps on the soil (they're visibly working too) and my own sugar, dish soap, apple cider vinegar concoction so it might be a combination of these things. Still not willing to leave out my cup of morning tea but I don't randomly see a bugger flying across my computer screen so I'm a happy plant lady! It seems to be working! I will continue to use it for another week for safety measures.
Overall, I would gladly order this blend again and it is a concentration so it will last me for a while. Also included a pic of my desk setup for attention!!! I'm so proud of it and feel very happy every day when I work there!!! Hope my plant folks out there can appreciate it too!!! :-)
