I am not sure quite what is going on but I have never had such a problem with spider mites as I have this year (it seems that fungus gnats are also way worse but that’s a post for another time)
This photo is of some office plants shortly before I took them to the dumpster (no compost pile at work). I am not sure quite what happened–if these plants started the infestation–as you can see, they are infested beyond saving–but last week we carted out a pothos that had been in the office forever. As I remarked, it predated me and I have worked there 12 years. So that was a real loss, but it was equally as infested as these plants. Which plant infested which, I don’t know.
I do understand why this happens so quickly at work. The office faces south and the building is brick. Every sunny day, the offices where our plants are heat naturally to very warm temperatures. So these insects, which love dry warm air, breed rapidly as they are known to do.
They have a much tougher time in my cold house, thank goodness, but I still have some, even there.
I just wonder why they are so prevalent lately when I literally haven’t seen them in years?I guess we are having a spider mite pandemic too. Sigh.
