Ants for Experienced ant keepers
As ants live in very different habitats with very different climatic conditions, you need make sure that you can provide the right temperature and humidity.
To keep the right humidity you simply need to moisten your ant farm for example with a spray bottle. When it comes to keeping the right temperature though, it gets a little more complicated. You either need a heat lamp, a heating mat or cable or heat the room, in which you keep your ants, to the right temperature.
Nevertheless there are many species you can keep at room temperature. Even if it is 1-3 C° below the recommended temperature it is usually not problematic.
