They eat a wide variety of animal food, both dead and alive, as well as vegetable matter and juices. We saw one eat the little ants on a crumb of bread and then eat part of the crumb. Although frequently active in daytime, they are primarily night prowlers and solitary in habit. Sometimes, however, several will form a tangled mass of bodies and legs and remain immobile unless prodded into activity. Then they stink.
Some people use perfume for the same purpose.
