Infestations of Crotch Gnomes are easily spotted by their tall pointy red hats. Not to worry though, while crotch gnomes may be irritating - have short stubby legs, and do not move very fast, making them easier to exterminate. Be sure to stay away from any small animals like Rabbits or Foxes, crotch gnomes are drawn to them.
Crotch gnomes maybe spread in the following ways:
Direct pubis to pubis contact
Excessive amounts of time spent in Nordic Countries
Hat making classes
Playing with foxes or rabbits
