    Unhappy Neem oil? Does it work for gnats?!?!!

    We've recently experienced some very steady heavy rains here in Hawaii and many of my orchids have suddenly sprouted gnats!! I know it's a by product of rotting media, but in this case many of the orchids were just repotted in June & July! It always seems that when we have heavy rains this happens.

    I used to use horticulture oil (I got it mail order) but I don't have access to that right now and I've seen neem oil in my local garden shop. Has anyone used it? Does it work for gnats? and is it safe for my 'chids?

    Thanks in advance for your advice & expertise!

    At least neem oil works the same as horticulture oil, not sure if it is good for gnats.

    I prefere to use neem oil over using checmicals. For me it does work very well. Although I am sure there quite a few people who would disagree with me. All I know is, that it works! Here is a good link to look up neem oil and it uses and what it does http://www.neemfoundation.org/organic%20farming.htm Hopefully this link will help you make your decision. I sware by it, and alot of people I know who have used it in lue of chemicals have also made the switch for the betterment of the environment

    Hi JW,

    I use Neem for all my pest control. Stronger concentrations for serious infestations. It won't hurt you or your orchids at all. I keep a spray bottle filled with it for foliar critters, but in the case of gnats, you'll want to soak the pot. Make up a bucket of it at either the recommended concentration, or slightly higher, and then give the pots a soak for a good 5-10 minutes. You'll want to do this every few days until your gnat problem is gone.

    I'm interested in finding more about the practical aspects of switching to Neem oil. I sure hate using the chemical sprays. I would like something nontoxic that would work against mealies. Do you have to take the plants outside to spray them? With cold weather this is getting harder and harder to do. Is it nasty in some way that would make its use for living area plants undesirable? A mess to use? That kind of info.

    I sprayed my plants with neem oil in bath room. One thing with neem oil is you can't spray in hot days, and need to keep the plants in shade after spraying, or the plants will be at risk of sun burn.

    I'm with Qing, Mehera. It's totally safe to spray indoors. It has a funky smell, but that fades quickly. It's good against mealies, but you have to dig them out of their hiding places and sometimes spray every few days for a few repeats to get them all. True with any insectiside.

    It's an oil though, so take that into consideration. You don't want to get it all over the place, so I stick a pot in the bathtub and spray away. It rinses off with the next shower!

    That's also why you want to keep a plant out of direct sun until the oil dries. It will act like a magnifying glass and fry those tender leaves!

    If you need a source for it, just PM me.

    The scent of neem reminds me of onion soup! You can tell when I spray from a block away. I also only spray in the late afternoon after the sun faded slightly to help avoid burns from the magnification of the oil.

    Could Neem oil work if I just sprayed it on the top of the potting media? I have an occasional gnat flying around and a bit of a mold issue, both will get worse as the Summer heat comes. It seems the mold is only on top and since everything is growing along good I don't want to "fix what's not broken". Does anyone else use it in this way?
