I have noticed a white insect crawling in the dirt of my indoor angel plant. I have washed it down using mild soap and water but it keeps coming back. I assume the white is the larva because I also see black flying insects around the plant. Please help on a organic method to kill this problem. Thanks. . .
It might be aphids. If so, this article might help: https://www.gardeningknowhow.com/plant-problems/pests/homemade-aphid-control-a-natural-way-to-kill-aphids.htm
If you see something crawling around in the soil, it's probably fungus gnat larvae. This article should help: https://www.gardeningknowhow.com/special/children/fungus-gnats.htm
If it is fungus gnats, one of the most important things to remember, fungus gnats love, love, love wet soil. Let the soil dry some between waterings.
