My spider plant has lots of little tiny white worms or larvae crawling in its soil. What are they?

And how do I get rid of them?

My spider plant has lots of little tiny white worms or larvae crawling in its soil. What are they?
Sounds like fungas gnats.





U of Colorado has a good piece about them, they are listed around the bottom of the page.





Shows photos which should help you identify as well as ways of managing it.
Reply:Mealy bugs, spider mites, white fly - seems you are in the larvae stage of one of those. Over watering / poor drainage can give these pest a good start. Best remedy is to totally repot / transplant. Empty entire contents into a trash bag and shake loose the plant itself. Try to shake plant of all dirt, etc. Then gently water sprayer through the plant/roots, then place in whole new set up. Would lightly dust with a bit of Seven Dust for good measure. I live in a humid area and most plantings are in ground - keep it all under control with dusts (spread sulphur dust everywhere in Spring). Seven Dust for incidentals.
Reply:Sounds like maggots so they will turn into flys soon. Dump the plant and burn it before they do.
Reply:Spray it with an insecticide for houseplants. Change the soil.
Reply:It could be plant mites. Hold it under a blast of water. If that doesn't work, spray it with an all purpose plant insecticide. You may have to get rid of it. Your other plants may get the mites.
Reply:My guess is fungus gnats - you probably water your plants too much. In general, let the soil dry up before watering and don't overfertilize them.
Reply:You don't have to burn your plant. Change your soil in your pot. Knock of any old potting soil, you may need to rinse of roots under water. Replant in a NEW pot with new soil. There are several all purpose sprays or powders you can use to control insect festation. Before using your old pot it needs to be scrubed out with hot water and bleach.
