    Nematodes or some larvae?

    I just top watered one of my VFT pots that has been showing some yellow leaves lately and slowed growth all of a sudden and as some of the water pooled around the bottom of the pot in a previously dry saucer I noticed that small peat debris in the water are slightly wiggling around. After a bit of concentrated starring i've noticed several millimeter long thin (thinner than hair) worms wiggling around... Some of them get stuck to small peat debris and that is what caught my attention initially

    Could these be the nematodes that are causing my VFT the harm? I don't think that these are fungus gnats larvae since the pot was in a dry saucer and these worms are just too thin and small. If they are how do I get rid of them?

    I tried taking videos where the wiggling of peat debris can be spotted. Can't see the worms with it though.

    Here they are for entertainment purposes:

    1) look at thecenter of the video frame


    2) center but slightly shifted right.

    Hey Gill,

    Indeed my eyes aren't as good as they used to be, so your video looked like dirty water
    with one piece of dirt moving about a bit!

    If it were me, since your VFT has been having a difficult time anyway,
    I would remove it from the pot and immediately throw away everything except the VFT!
    Then I would run it under the tap with temperate water, to wash it off a bit.
    Then let it soak in a cup of clean Rain/R.O./Distilled water for the day.
    This should encourage any "bugs" to go-a-swimmin', leaving a nice clean VFT!
    I would then pot it up in a new pot with some new mixture.

    You could use something else on the plant to kill off anything left, but in my experience,
    just cleaning things off real good works just fine,
    and avoids using things that may just complicate the issue if not done properly.

    Well, that is what I would do, FWIW.
    Good Luck
    Experience is the best teacher. At least it used to be.
    But then, common sense isn't so common anymore, is it.

    Thank you for the advice. I do realize the videos don't do the justice to the horrors I've seen swimming in that little tray, I pasted them just to make my post less plain

    I've since have been looking around my custom google search and found few posts here and there where people suggest using imidacloprid containing sprays to poison the little ba****ds. Also neem oil contains azadirachtin so I will attempt to mix this into their diet as well.

    If all fails I'll be forced to repot it. My problem is that I will have to repot all my plants because I have definitely contaminated my little collection when I was shifting pots around and swapping them temporarily between the trays...

    I'll get the insecticide today and pick the worst looking VFT to test it on. Will try both neem extract and imidoclorpid (hopefully they will not react with each other) together and report back what I find.

    P.S. I wonder now why i did not see them before, I suspect that after I initially applied neem, nemathodes migrated deeper into the pot and some got washed out with the last watering.

    Im like Paul, only probably with worse vision LOL

    ummm but just for laughs and giggles.... Brownian motion?

    CP particle theory woohoo, Ive always wanted to combine the two (Carnivorous unification? LOL)

    now my brain hurts really bad

    Well If I could see particles down to micron size with my much abused eyes my brain would probably also hurt.
    But unfortunately no dice... the theory you proposed will have to be scrapped.. Those are worms... and they boogie like this (close enough):

    plant parasitic ones tend to move sort of slowly. There are free living and ones that eat other nematodes.



    is a quick and dirty I shot via a microscope and USB2 cam attached to it. infective larvae of a rootknot nematode that was extracted from tomato roots.

    Well maybe the ones I got are hyperactive from all that neem oil extract I dumped into the pots previously...
    What about the human parasitic ones? Do they move fast?

    /me crosses his fingers and mutters really fast: "i hope i myself wont get any worms after this, i hope i myself wont get any worms after this....."

    Nothing significant can be made of your videos.

    I'd be a bit more cautious when "dumping" chemicals or insecticides on my plants, especially when mixing stuff that is not normally sold or found as mixtures. Just because Neem Oil is "organic" it doesn't mean it can have harmful effects on plants or humans. Yeah, it's "organic" or "natural', so what? Hydrogen Cyanide can be derived from peach or grape seeds. Does that make it (in enough concentration) any safer?

    In Barry Rice's "Growing Carnivorous Plant" it was mentioned that when he treated plants in a terrarium with Imidacloprid it killed the worms in the medium. Even though he was most likely talking about earthworms (annelids). Oh the Horror...the Horror...growing CPs in a terrarium! Well he didn't actually say they were CPs but in a book about Carnivorous Plants...
    Grand Hotel... always the same. People come, people go. Nothing ever happens.
