i have a few boxwood's at the back of my house . for the past 3 weeks if you stand near them it sounds like a bowl of rice crispy's . now i just noticed all of a sudden on the ground around them it looks like ground up boxwood leaves and some leaves that look like they were broke off . does anyone have a clue what type of bug is doing this ? i plan on cutting them down because they are so close up to the house it is causing mold on the side of the house . but i am worried that what ever type bug it is may get in my other bushes and plants . any help would be greatly appreciated . thanks in advance
