Fungus Gnat Larvae?

[Miguelito's Blade]

Yesterday I was repotting a satsuki azalea. It came from a local nursery and it was a mess. The water had stopped draining, the root ball (as I discovered) had a center of mainly mud and dead roots except for one spot of white, healthy roots. The bottom of the pot was deteriorated substrate mud, and throughout the pot had a goodly amount of styrofoam. At any rate, I trimmed away as much of the dead roots as I was able, and put it in a training pot with 100% kanuma. As I was finishing with a small addition of soil to bring the level of the soil up to just below the rim, I saw on the base of the trunk a small, white, constantly wiggling worm. It was about 1/8 inch long. I should mention that the base of the trunk was covered in moss as well, which I removed. I read in another post about a similar pest and it was decided to be a Fungus Gnat Worm. I sprayed the tree with Sevin but I resort to your collective wisdom to tell me what more I need to do.

If you see a cloud of gnats forming you need to do more. If yu now have 100% kanuma, there will be very little for gnats to be attracted to. Leave it alone. Let it grow.

All pots have a host of things living in it. It is not a sterile environment. Let nature sort things out, while you create the optimal environment for your tree to thrive. Keep an eye on things.

Thank you for the sound advice.
