You mentioned pest control in the soil - have you tried mosquito bits? I ended up mixing some in with the soil for a Monstera and I also put a layer over the top and it does seem to make a difference. I do have to combine it with those unsightly yellow sticky traps, though. Between plants and the inverts I keep, my house is full of containers of damp dirt.
In case anyone is thinking about getting a katchy, you can read the reviews, but I give it a thumbs-down. I used it only a few times before fall and it worked okay, but when I pulled it out again in the spring I just get orange error lights and no response when I reached out to them.
I’m glad you’ve had better luck with Katchy than I did. I bought it because of a personal recommendation, but it didn’t really work long enough for me to determine if it was better than sticky traps.
Plus I’m the weirdo with a soft spot for moths, so I just generally leave them to fight it out with the spiders :). I cannot handle the fungus gnats flying up my nose, though. It doesn’t seem to matter if there is one fungus gnat or fifty - they all think there’s a party in my nostrils.
