I ordered neem oil because there were extremely tiny bugs crawling along my orchid pot and I was concerned they were harming the orchid. It turns out that they are probably just eating the decomposing moss medium, rather than the plant itself, and the neem oil did not stop them as they appear to live within the substrate, but I just need to repot to fresh medium. I believe they are springtails, which are harmless to plants if not beneficial.***However***, the very same day the neem oil arrived, I checked on the orchid to apply the oil and there was new webbing all over the leaves. THAT is definitely a problem as it indicates a pending invasion of spider mites. Since it's springtime now, we have had the windows open, which is likely how one came in and started laying eggs. I absolutely doused every part of my orchid with the oil spray and then removed the webbing and wiped the leaves with paper towels. It's been a couple days now and there are no signs of spider mites (just springtails). I’m very happy the springtails arrived because they caused me to purchase the neem oil just in time, *before* the spider mites could hatch.It's for this reason that I actually recommend buying neem oil before you even need it, because every plant owner deals with pests at some point. It was only a matter of time for me. Be sure to isolate any plants that have pests as soon as possible.In regards to this specific neem oil, I appreciate that it came with a spray bottle so that I didn't have to buy one or use one of the few we have, and it also has the instructions on it, which is convenient. It's super simple to get ready--just a specific amount of pumps combined with water (though I do wish there was a fill line). The oil doesn't smell bad at all. The only downside is that the oil gets all over the surfaces you spray it nearby, but that is to be expected given that it's oil--which also means that it's a little difficult to simply wipe up, as opposed to water. I recommend laying an old towel down.In conclusion, get the neem oil now, before you regret having waited!
