It works.
I’d never used organic anything in my garden before last summer. I ordered a 2 pack of captain jack and, let me tell you the gods honest truth, I will never go with another brand. Ever. The best thing I can say is that captain jacks products work. I don’t care one way or the other about it being organic. I just wanted something that would work. Big business always seems to be cutting corners so you can’t count on the big names these days because you may get a bottle of neem oil that is diluted or watered down and don’t half work. I don’t have a big garden. Actually it’s pretty small. Despite its size I put money in gardening: good seeds, fertilizer, time spent tilling, pulling weeds and watering. So do a lot of other folks with big gardens. It’s a great feeling to get your moneys worth in this day and age. Go with the Captain. He works.

This has helped my indoor fungus gnat problem immensely! I took my plants outside and doused the soil, mixing it into the top layer, soaking it. I then sprayed the leaves all over and let them dry outdoors before bringing them back in. (It’s a little stinky). I have been using sticky traps for the gnats that are usually covered in a day and day 1 after spraying and there are no signs of survivors! I will keep spraying on a biweekly basis or if I notice gnats again. Worked great!

5.0 out of 5 stars Works great, but there are more cost effective options
Reviewed in the United States on October 23, 2023
Style: Ready-to-UseSize: 32 ozVerified Purchase
Unfortunately, my plants get pests (which I guess is one of the challenges that makes owning plants so rewarding). Captain Jacks is super good at getting rid of the pests that are on the leaves, and it is super convenient to have the insecticide solution premixed in the bottle. However, I think it is a bit more cost effective to buy the neem oil separately and make the mix on your own. This is especially true if you have many plants that need to be treated over a period of time. Given the fact that you are supposed to soak the plants once a week with the spray until the infestations is managed, the spray is used up quite quickly.

4.0 out of 5 stars Miracle product with a bad smell
Reviewed in the United States on April 15, 2024
Style: Ready-to-UseSize: 16 ozVerified Purchase
I struggled with gnats on my house plants and all online resources pointed me to neem oil. This spray works SO well. I spray it on my plants once a week and it has done a great job of removing and repelling gnats. The one downside of the product is that is smells like rotten eggs and sulfur. It may have more to do with neem oil than this specific product but it is not for the faint of heart. It only stinks right after you spray it so I try to spray it before I run errands and it makes it bearable. I would say the efficacy of this product definitely makes the smell worth it!

My Hawaiian plumeria plant was covered in white spots and was not looking healthy. It lost all of its leaves and was basically hibernating. I determined the culprit to be a white mold common in my area for this species, So I sprayed this on it and waited a week and my plumeria is back to normal, sprouting leaves again just in time for spring. It doesn't smell horribly but then again you should be smelling this thing when spraying.

My house plants got gnats and I tried everything to get rid of them. I was using another spray product which I mistakenly thought had neem oil in it. It has essential oils instead. I bought this along with the Zevo gnat catchers. I sprayed this on all of my plants and it took care of the problem with one use! I would definitely recommend!
