Heat Cable
Definition
A flexible heating wire placed under or behind part of an ant nest to keep it warm, which speeds up brood development, ideally controlled by a thermostat to avoid overheating.
A heat cable is a thin, flexible heating wire that ant keepers use to warm a nest. Together with heat mats, it's the most common external heat source in the hobby. Ants are cold-blooded, so a little extra warmth speeds up their metabolism and helps the
You usually place the cable under or behind part of the nest. Some nests are designed for it: the WaKooshi Venus nest has pre-cut ports to pass a cable under the test tubes, and the Esthetic Ants
A heat cable is most useful if your room is cold or air-conditioned. Lasius niger, for example, does fine at room temperature, but grows faster between 23 and 25 °C. Messor barbarus likes it between 21 and 26 °C.
The danger is overheating. Without control, a heat source can practically cook a colony.
In practice
- Use a thermostat to regulate the temperature automatically.
- Heat only part of the nest, so the ants can move the brood to the temperature they prefer.
- Check your species' ideal range first and keep a thermometer near the nest.
- Turn the heat off during
hibernation , and don't let the cable dry out the water reservoir of a test tube.
