Bonide Captain Jack's Neem Oil, 32 oz Ready-to-Use Spray

My hibiscus plant was affected by aphids and the buds used to fall prematurely. From the time I have been using this spray, the buds are blooming. It has drastically reduced the number of aphids. Though it has a strong smell which I dislike, as a spray it’s doing its job.

I don’t really know if it’s doing anything. Nice for peace of mind if nothing else. My tomatoes haven’t been eaten by bugs so no complaints.

Helps fairly well with plant pest infestations. It doesn't keep them away very well though. As I keep having to retreat my plants. Working on a different solution, but I will be repurchasing this. I am happy that none of my plants were adversely affected by this, as they have been by other pesticides.

I tried everything to get rid of the fungus gnat infestation started from a fb marketplace indoor plant, and this stuff was a godsend. I recommend repotting highly infested plants completely, and directly spraying the roots before potting into fresh soil. If you don’t repot, you will need 2-3 rounds of drenched soil, and should do it outside if possible. I was able to do two rounds of drenching on seven 6” pots, three 12”, and four 8”, and still have some leftover. This stuff isn’t terribly stinky, but it doesn’t smell great and should air out; especially with pets, kiddos, and sensitive noses. I used the solid stream setting and sprayed directly on the soil until it was completely wet. You can always propagate and start fresh if all else fails :) it gets better and there is hope!! No more embarrassing gnats, yippee!

I have always heard that Neem was really effective, but I was honestly pretty skeptical that it would actually work. But I got white fly, powdery mildew, and rust on my Star jasmine vine, and I was so upset, and then it started spreading to other nearby plants and I knew I had to do something ASAP. I have lots of cats that love to spend time in my garden eating grass and rolling around, so it was really important to me that I didn’t use any sort of pesticide. I use this brands fertilizer, and it is excellent, so I figured I would try their Neem Oil. First, you have to coat all the leaves really well and this product makes it so easy to do that because the spray bottle is so excellent. I wish I could have the spray bottle for all of my cleaning products and anything I ever have to spray. It gives a nice healthy coat to all your leaves with very little effort. I just let it dry and a few days later did it again, and then I fertilized, and now my jasmine is not only fully healed, but blooming again and sending off really happy new shoots of growth. I will never use anything else.

This neem oil spray works well for mild pest issues and is convenient since it comes ready-to-use. I appreciate that it’s organic and can be used up to harvest. However, the spray nozzle clogged a few times, and the smell is quite strong (though that’s expected with neem). It also didn’t fully clear up a persistent aphid problem on my roses—I had to reapply more often than the label suggests. Good for maintenance, but don’t expect miracles with heavy infestations.

This product is awesome. Living basically in the woods, I bought this product to spray on my outdoor potted plants to rid them of bugs to bring them inside. So far so good. I have an extreme situation with brown recluse spiders. I have a tarantula so I can’t treat indoors, I use different products. But, I sprayed this product on outdoor spider webs while treating my plants. Within several days, I stopped seeing webs, recluse. Researching said a neem product will not kill recluse on contact, but, will kill them within several days of contact. Not only does this rid your plants of bugs, it’ll do the same to your deck. I highly recommend it.

This is hands-down my go-to spray for keeping insects under control in my vineyard. I’ve tried a lot of products over the years, and Captain Jack’s Neem Oil is the one I keep coming back to. It does an excellent job of controlling soft-bodied insects and mites without harsh chemicals. Since it’s labeled for organic gardening and can be used up to the day of harvest, I feel comfortable using it on my vines. The ready-to-use 32 oz spray bottle makes it super convenient — no mixing, just spray and go. Coverage is good and it doesn’t leave a heavy residue. I use it preventatively and at the first sign of pests, and it consistently helps keep populations down. The 3-in-1 action (insecticide, fungicide, and miticide) is a big plus because I’m dealing with more than just one type of problem out there. A couple of practical tips from my experience: • Spray in the early morning or evening to avoid leaf burn in hot sun • Make sure to coat the undersides of the leaves • Reapply after rain if needed If you have a vineyard, orchard, or just a lot of plants you want to protect organically, this is reliable stuff. It’s earned a permanent spot in my spray rotation. Highly recommend.
