If you keep beetles or stag beetles, as autumn deepens, you might find yourself wondering, "How should I care for them in winter?" The overwintering of insects is not difficult if you have the right knowledge. By managing larvae and adults according to their respective characteristics, they'll show you their healthy forms come spring. In this article, we'll explain winter care and management in detail.

Larval Winter Management: Continued Slow Growth in Cold Temperatures
Beetle and stag beetle larvae don't completely stop their activity during winter. As temperatures drop, their metabolism slows, but they continue to grow steadily while eating the bedding little by little. For this reason, it's not okay to just leave them during winter—you need to continue providing minimal care.

Bedding Change Frequency and Methods
Winter bedding changes should be done approximately once every 2-3 months. Since larvae eat less compared to the active summer and fall period, frequent changes are not necessary. However, if the bedding becomes covered with feces or shows significant deterioration, replace it sooner.
When changing the bedding, work as quickly as possible to minimize the time larvae are exposed to low temperatures. If you bring new bedding to room temperature beforehand, you can reduce the stress from temperature changes.
Key Points for Humidity Management
Humidity management is especially important in larval breeding. If the bedding becomes too dry, larvae weaken; conversely, too much moisture promotes mold and bacteria growth. The ideal condition is firm when squeezed but not crumbly—when you squeeze it in your palm, it holds together and then breaks apart slightly. If the surface becomes whitish and dry, gradually add moisture with a spray bottle.
Choosing the Right Location
Containers should be placed in a location without direct sunlight and with minimal temperature fluctuations. Suitable spots include indoor hallways, closets, or shelves near entryways. However, if temperatures drop below freezing even in the entryway, move containers to a warm indoor location. Rooms with excessive heating also promote drying, so regular humidity checks are essential.
