Bonide 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

While this sprays out way to much and way to fast the only problem I see is it not lasting by the time you finish one plant it is gone But it works great. The smell is nasty. And the directions while clear are scary. States if it gets on you to wash for 25 min scrubbing each area for 25minutes. And call poison control. Nothing about why or anything but I did get it on me and I didn’t grow an extra horn so idk. Does it kill bugs I’m not sure as grasshoppers and something are still eating holes in my leafs outside plants I fear spraying indoor plants as the jet of power when it sprays out is strong might hurt tiny indoor plants I wish there was a setting to tell it to calm down.

No gimmicks just Neem oil spray that takes care of the gnats and fruit flies on contact. The battery sprayer was a real surprise and also very convinient , not sure why they don't highlight it in the product description.

I bought this because my vegetable garden and a few houseplants were dealing with aphids and early signs of powdery mildew. I wanted an organic option that would protect without harsh chemicals. The 64-ounce bottle and the idea that it acts as an insecticide, fungicide, miticide and nematicide sounded like a practical all-in-one solution for my outdoor and indoor space. In everyday use I shake it well and spray it on affected leaves or drench the soil around seedlings. It’s ready to use right from the bottle, which is handy, and I can apply it as a spray or a soil soak depending on the issue. I used it on tomatoes, peppers, and a few potted herbs, and I noticed pest pressure ease within a few days. It targets eggs, larvae and adult insects, which helps prevent reinfestation. What stood out most is how gentle it feels compared to harsher chemicals while still delivering visible results. The option being plant based and approved for organic gardening gives me confidence to keep using it. I also appreciate the size, since a 64 oz bottle lasts longer than smaller sprays, especially when you have a mixed indoor and outdoor setup. One small note is that like any garden spray, it has its limits and you need to follow the directions for application frequency. It has a mild scent and may need a few hours to dry, but those are minor tradeoffs for ongoing protection. Overall, I’m happy with it and would rate it five stars.

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.

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.
