Captain Jack's Neem Max 12 oz Ready-to-Use Spray for Houseplants | Multi-Purpose Fungicide, Insecticide, Nematicide and Miticide for Organic Gardening

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.

Quick shipping. Good value for the amount. Natural effective way to protect your veggie garden. The odor is noticeable but light enough to ignore.

Sprayed my lilies top and bottom sides and left for a week and they are still alive with some holes from the beetles; but last year they were completely eaten and gone before blooming. Happy about seeing flowers!!!

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, lost 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.

Spray hose did not work and was the only reason i purchased. For easy handling. Otherwise i would rate 5 stars. Smells weird, but Product works. I had thrips on all my indoor plants after washing them and applying Product every week most pest are gone. Plants are healthy again. Good size for cost.

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!

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 grow most of our veggies and indoors under lights year around, and bought this neem oil primarily to eliminate spider mites that I brough in with an online purchase. I did get the battery operated spray, but I use a spray bottle that dispersed the spray more evenly. Neem oil will kill bugs and eggs, but it is a contact spray and must be sprayed directly on eggs and bugs to kill them. Leaves must be sprayed top and bottom, stems must be sprayed, and even the soil must be sprayed for any bug or eggs in the soil. Especially when the plants have a lot of foliage, multiple sprays are required in an effort to spray all of the bugs and eggs. For something like spider mites, this means spraying the plants thoroughly every other day for up to 2 weeks. If you miss any mites or eggs, they start reproducing all over again. For example, a spider mite female, within a few days of hatching, can produce 8-20 eggs per day and live up to 3 weeks. That means that one female spider mite, if left undisturbed, can theoretically produce 300+ eggs by the end of her life. If you get spider mites, you must be diligent in consistent spraying to prevent a severe infestation. I have been battling spider mites for a couple of years, and I can't honestly say you ever get rid of them. About the best you can do is to control them. If you do have spider mites or other bug problems, this gallon bottle, since it is ready to use, will not last long depending on the number of plants you have. It might be more cost effective to buy a concentrate that needs to be diluted. If you have a number of plants to spray, as I do, this gallon bottle is a good size, but is not cost effective. I do like that this spray is all natural and not toxic, but there are other options for concentrated sprays that are added to water that last much longer. This spray is effective as a contact spray, but the key word here is "contact". If you miss one female or one egg, they can start up all over again. I hope this review was helpful for you.
