There are some guidelines when it comes to taming those sprouts, and no matter how many you get, you will want to treat them all the same. Most importantly, DO NOT pull on the sprouts, as it can remove strands of wool and create a small hole in the rug, or worse, damage the warp and weft. The best way to remove them is to take scissors, and with the blades parallel to the pile, trim the tuft off so that the surface of wool is even with the surrounding rug.
Some people may worry that they will cause damage to their rug by trimming the sprouts. Fear not, trimming the sprouts properly should not harm the rug. To understand why trimming the sprouts is not harmful, let’s better understand why the sprouts occur in the rug in the first place.

One type of wool yarn used in rugs is created by hand twisting the fibers. This yarn can be fashioned with either a drop spindle or a hand turned spinning wheel. Because both practices are basic spinning methods, there is some variation in the yarn. This variation is what gives handmade rugs their charm and individuality. The image below illustrates how different the strands of yarn can be, and you can see where the sections of yarn are looser or tighter depending on the weave. The yarn shown was specifically created to have a high amount of variation to highlight the artisans work; the yarns used for hand knotted rugs typically does not have this much variation. The photo also illustrates how each strand of yarn can have sections that are more tightly twisted than others.
How does the sprouting process happen? Over time, the sections that are not spun as tightly can relax and lengthen. As they elongate, the individual fibers sprout up out of the knots that create the rug. This will be most notable in high traffic areas. It does not mean the knots are coming undone or damaging the essential structure of the rug. In trimming off those fibers, you are not harming the rug.
