Nematodes in house plant? #680042

Asked February 03, 2021, 8:36 PM EST

Hello! I found a very sad Monstera plant a few weeks ago, I assumed it had root rot because the soil was SO wet and moldy and the leaves had signs of root damage. It was still pushing out new leaves though so it seemed like it might survive. I took it home and it has been living in a sunny window and hasn't been watered in about a month. The soil is still quite damp. It appears to be doing better than when I first found it. A few days ago a leaf turned yellow rather rapidly, so I went to check it out and the leaf came out of the soil in my hand, with little worms at the very base with the soil. The worms are very very very tiny and clear. They have no distinct head. They are so tiny they are practically impossible to capture in a picture, although an attempt is attached. Upon further inspection they are clearly eating the living tissue of the roots. To me they look like nematodes, although I know most nematodes are microscopic. I am looking for some kind of control but can't find any nemacides in stores nearby. I am hesitant to buy a giant container of nemacide online just for this one plant. I am looking for a place to buy a small quantity locally, or other solutions that would rid the poor plant of the worms. I live in an apartment without access to a yard or hose or outdoor sink, and am hesitant to try and bare root rinse and re-pot an already sick plant. Any advice would be greatly appreciated!

It may be that this particular house plant is damaged beyond repair and it may be the best decision to compost it and begin anew.  You could also replant with new soil, add fertilizer and wait for any improvement like more vigorous growth and or new leaves rather than adding pesticide to the soil. Good Luck with the ailing plant.
