It works and doesn’t make a mess!
This is amazing just two sprays and my little insect problem is gone. The item does not smell bad and does not make a mess. I use this on Millie bugs in an enclosed area and had no problem at all. I definitely recommend following the directions on the back and keeping a paper towel just in case. This is a great value for my money and I believe this small container will last me all year if not, two years. I sprayed my plants several weeks ago and still have not had a reoccurrence of insects. Highly recommend.

Works great
Have spider plants and learned the hard way they attract gnats! Lots of them! Use this and they were gone quickly amd stay away! Does have a slight smell if you are sensitive like me but not bad or overwhelming

Smelly
This stuff smells so bad. Better open window if you have indoor plant problems and need this. I have been using it for months and have seen little help with my insect issues. Makes a mess. Good thing its natural ingredients. It sprays really nice and had the spray and stream option.

Super affective
I’ve used it on succulents, plumerias, houseplants and exterior plants such as potatoes, strawberries and corn. Been affective for mealy bugs, I forget the species however one succulent had an infestation (this took probably a couple weeks of treatment) and even caterpillars! I did save the most impressive for last, one of my Desert Rose (extremely difficult species) came with a caudex whose whole bottom half was mushy with a fungal infection so my first thought was I had to cut it in half, dry it out and hope for the best however as is usually best with this plant I had to exercise restraint and think of a different plan. Then I thought of trying this stuff and it’s actually working! Awesome product, it does take time and sometimes lots of applications so it’s not an immediate result and isn’t designed to be. Also it smells realllly bad. Will always have this on hand

Plant saver bug killer!
This was a life saver/plant saver! We had so many gnats from our plants that were literally swarming around the house. I tried all of the home made stuff and nothing worked. I really didn’t want to have to throw out all of my plants, so this was a last resort. I’m so glad I got this! Within one use, the bugs were already highly decreased!! I just didn’t realize that the smell would be so potent and gross (whatever works) so I recommend to spray the plants outside. That’s what I did the next dose, and now the bugs are gone and my plants are saved!!

Effectiveness is Questionable, But It Seems to Work Somewhat
It is hard to tell how well this works because some plants just get hit quickly by fungus and other issues when outdoors. Other plants survive all conditions. I use this on roses and other similar plants and it seems to stop the spread. For longevity, it really depends on the weather and where your plants are situated.

Grade: A
My green babies and I Love this product! This need oil gives all my plants a little shine and perks them up when sprayed at the base and soil. It’s very effective and has good longevity. Premade and arrives ready which makes it easy to use. It’s not sticky and doesn’t have an odor until I add oil. . I like to add pure peppermint oil to it to help deter bugs. I only use two brands of Neem oil and this is one of the two.

Ready to Use Neem Oil Spray for Indoor and Outdoor Plant
I used this spray on indoor plants and outdoor containers as part of routine pest control and maintenance. The ready to use formula applied as a fine mist that coated leaves evenly. Once dry, there was no visible residue, spotting, or leaf damage. I did not observe buildup on leaf surfaces or lingering odor after application. The spray functioned as a straightforward option for regular plant maintenance and preventative use.
