Well ive had a garden in my window for about two weeks now and all the plants seem to be doing great except for one. My cilantro was mostly dead this morning and while looking over it i noticed a bunch of small tan and white bugs living on it. 5 or 6 of them actually.

My question is are these spider mites? And do they pose a threat to the rest of my plants that were growing near the cilantro?

Thanks in advance
