    Apparently jimscott's experience isn't the same,
    though I realize it's printed on the bottle.
    Good growing, Jack

    Neem oil is a low or short persistence oil - it evaporates in about 3 days - which is why it is relatively safe to use on CPs. For insects that rapidly reproduce like aphids spray twice a week.

    The instructions must also be followed in order for it to be effective, e.g. spray all surfaces (top and bottom) until runoff. This can be a problem with decumbent or ground hugging leaves as often found on Dionaea.

    This isn't from experience. I've never used it. I have only drowned aphids and once used the Bayer product for roses. Where I am deriving the info about aphids is directly from the link provided by Fryster. Here's a copy and paste"

    However, this does not work for all insect species. The neem ingredients accumulate in the tissues deeper inside the plant. The phloem, the outermost layer, contains hardly any. A tiny aphid feeds from the phloem, it can not penetrate deep enough to get a dose of neem. But any leaf hoppers, grass hoppers or similar chomping insects will be incapacitated quickly.

    People eat neem leaves to cleanse the blood, stimulate the liver, and boost the immune system. So we certainly don't need to worry about a bit of neem inside our lettuce leaves. To me this is a much more attractive option than having poisonous foulicides build up in my garden.
    Neem oil suffocates insects

    Many gardeners use white oil (plain mineral oil) or even olive oil to combat soft bodied insects like aphids, thrips or whitefly. The oil coats the bugs and they suffocate. Neem oil insecticide does that as well. But it's more like a little bonus on top of everything else it does.

    I just bought Schultz's Garden Safe.. from Lowes. My Home Depot doesn't carry it. I'm looking at the label for instructions for the use / application. There are none.

    There weren't directions. I looked. All that was on the inside was precautions and first aid, in more than one language. But then again, the label was already open. So maybe someone else had it and returned it. IDK... but I did look. I'm not that stupid!

    I wasn't taking a jab at you, so sorry again J.S.
    I just meant there is much to learn of a label.
    I also have had a hard time with aphids and neem as a control.
    It will work on them but once you've got an infestation,
    I'd probably go with the bayer too.
    One for my head, some for the plant, cause sometimes I am that stupid.
    Good growing, Jack

    I hear ya... on more than one level. All is cool. The plants, themselves, right now, look like "death warmed over", after applying the product. I just have to wait it out.
