Captain Jack's Neem Max, 128 oz Ready-to-Use Spray Cold Pressed Neem Oil, Multi-Purpose Insecticide, Fungicide, Miticide and Nematicide for Organic Gardening

I started using this back in 2025 and I’m telling you it works so good on plants that you think have no life. It brings them back to life. It’s wild. It stinks like urine but I don’t care it does the job.

I love this product. The sprayer wand and apparatus is so much better than trying to hand spray the plants, especially trying to spray the underside of the plant which is needed for adequate parasite control. My affected plants are healthy again and have never looked better!

While I didn't have any pests to get rid of per say I do use this pretty routinely on all my houseplants as a preventative and to keep pest issues at bay. Also, this is a great spray to use on new houseplants when bringing them home to prevent any pests infecting other houseplants. This and also wiping down the plants with neem oil wipes. Will reorder when needed.

This is a high quality product, perfect for organic gardening. The price was good; however, the product shows a sprayer with this bottle, which is why I bought it, but no spray attachment came with the bottle. I will have to find another way to put it on my plants, which is disappointing.

I’ll give it one star for now. Only because the spray mechanism did not work. Product came fast. I put it into a little cheap hand sprayer and sprayed it all over my flowers and flower beds because the caterpillars are destroying my flowers so did not want to wait on a replacement bottle. Don’t know how that is going to effect the product being effective or not, I've never used this product before so don’t know how well it works. I hope it helps because i went organic instead of a actual chemical pesticide. If the product actually helps i might come back and give it a few more stars. Well i won’t be giving it anymore stars, everyday since i applied it still seeing the caterpillars that are destroying my Lilly's.

I wanted something to combat fungus gnats in the soil of some of my house plants, so I ordered this product, with the sprayer wand, which makes it very easy to use. I have a couple fiddle leaf fig plants which are notorious for getting gnats in the soil, yet they are not happy about being repotted with a soil change, so what to do? I sprayed the entire plant outside- under the leaves, on the leaves, stem and the soil surface as well. I know I may have to amend this process with another soil Bonide treatment, and that's fine, but the neem oil in the Captain Jack did a beautiful job of treating these huge leaves. At first the spray left white dots, and I thought I would have to wipe off the surface again but once dry, the leaves are gorgeous, shiny and clean looking now that the spray has dried. I see no evidence of bugs, so mission accomplished~ The battery-operated wand makes this very easy to use but do spray outside if you can.

Been using this for aphids indoors for about a week now, there’s certainly less of them. I’m hoping another week will see all pests gone. I’ve had other neem oils have pungent smells in the past, so I was happy that this one only has a minor odor. Regardless, post two stars for the worst possible spray mechanism ever. It is not the spray nozzle pictured (which works well), but instead one that is difficult to press and ineffective at dispensing the product. Instead it barely sprays and most drips onto your fingers and makes a mess. Hard to control bugs when you can’t spray the product on your plants. Cheapest quality bottle ever.

I’ve been using this neem oil spray on my citrus plants, and it works really well. It’s very easy to apply since it comes ready-to-use—no mixing or guesswork needed. After a few applications, I noticed a clear reduction in insects, and my plants look much healthier overall. What I like most is that it helps keep pests away without being too harsh on the plants. I’ve used it regularly as part of my routine, and it’s been reliable so far. If you’re dealing with bugs on citrus or other garden plants, this is a solid option that actually does what it promises. Would definitely buy again.
