I've been noticing these bugs on my house plants for a while and at first I thought it was just a few wondering in from outside but there are too many of them now for that to be the case. They aren't very active. They usually are sitting still and eventually die. But their droppings are quite annoying little brown puddles. And I've been finding them all over my house. They especially like sitting on my house plants. I don't think they are eating them but I would like to know what they are and know where they are coming from. Anyone else familiar with these guys? Thank you for any advice or help with what to do about them.
