An untrained eye believes a Borstel to be a very uncared for hairbrush or fluffs of dust and hair. Borstels live in every civilization or even animal tribe that allows for furr-knots. They hide as unrecognizable dust bunnies or bird nests. Not really dangerous, but annoying since they clog up drains and love to start dancing on the floor as soon as you put the vacuum cleaner away. Really greedy and bold Borstels try to eat the hair still on your head. A loss of hair and empty patches might be the result.
How to fight it
Keep your house spotless and vacuum every tiny little area. They are just dangerous as hiding place for other monsters.gab
