I'm having a big little worm problem with my houseplants. They are about 1/3 to ½" long. There are hundreds of them.

They do not seem to respond to gnat larvacides. (Knock out gnats)

I am currently soaking the soil with the larvacide and when I see other bugs I used Prynol. These other bugs look like the mature fungus gnats. I see very few of those.

The worms do not seem to be affected by either the larvacide (knock out gnats) or the Prynol insecticide.

I have also recently been seeing many small round bugs. About 1/12" long with legs. When I see those I spray and soak the soil with Prynol.

Help what can I do to get rid of these bugs aside from throwing everything away.

Some of the plants are edible.

Thanks
