What are those maggots on the roots of my dead lettuce plant? (lemmy.world)

When one of my lettuce plants started wilting, I pulled on it and found I could just pull it straight out of the soil with no resistance. On the roots, I found these maggots. (You may need enlarge the picture a bit.)

Does anybody know what these are?

How likely is it that those are why the lettuce started dying?

Can they spread to other nearby potted plants?

What can you do against these?

They don't harm the plant, nor any people. They're just a nuisance when the plants are indoors, because then you've got bugs flying around indoors.

Watering with mosquito dunks tea, and sticky traps placed to touch the rim of the pot (since they like to walk up to the highest point before flying) worked to eliminate them for me.

    They don’t harm the plant

    I don't buy this. I just caught them going through the roots of a plant with severe root damage visible. Granted, this was in combination with overwatering, but still. There are also plenty of voices in the Internet saying that, if those larvae run out of other organic material in the soil, they will start eating plant roots.

    Right, they're infesting the plant because of the root damage. You gave them a great food source. But if they run out of damaged roots, they won't start in on the healthy ones.
