11.10.23 in post #35 I mentioned microwaving the soil you can search to kill White Fly, Aphid and Gnat etc eggs for indoor potting soil. I have a Katchy black light vacuum from Amazon for attracting fruit flys, Gnats, Mosquitos and Moths. House flies will go to it but it has to be on 24/7 since they are dormant at night. The pests dehydrate and stick to a tacky disposable disk that is optional. I make my own from Raid window Fly clear sticky strips.
