Yes, and I just don't understand it. I have a handful of plants that live on my back porch year round, but they never show any sign of pests. But just as soon as I bring in a plant from outdoors....BAM! The whole room is overrun with bugs! I don't have a problem with bugs in the GH unless I try to bring in something from outdoors. And what's really stupid is that I NEVER see any sign of infestation when the plants are outside. I think the plant gods are trying to tell me: "You live in Northeastern Washington. It gets COLD in the winter. You are NOT allowed to have green things in the winter here!"
