Spider Mites: Swim or Die!
Don't mind me, I'm just ranting.
I am in the middle of my second SM outbreak in my sunroom (first was early Dec.), I slacked off on running the humidifier and the mites gained a hold. It seems blasting them off in the sink daily wasn't enough to keep them off the undersides of the leaves. Currently am completely dunking each plant daily in a bucket of warm water + a few drops of soap to see if the little witches can float.
The good news is that the fungus gnats have completely succumb to the mosquito dunk product, and it's not a problem to use it daily for maintenance. There's a cheap product called "Mosquito Bits" which comes in a shaker ($11.00, I've not used a quarter of it in a month), and I am shaking a tsp or less of bits into the water daily.
