They attacked those who were lost, and though they were extremely dangerous to lone Muggles, a wizard or witch could easily repel them with charms and hexes. They could also be repelled by dousing them in Beautification Potion, as their temporary "beautiful" appearance was repulsive to them. Red Caps were normally around three or four feet tall, with red eyes and long, sharp nails. Red Caps were most often found in Northern Europe.

Red Caps were less dangerous during their mating season, as they became more interested in attacking each other than any invaders of their territory.
