What Can Go Wrong When Using Beetles?

April 5, 2026

Quick Answer

When using beetles for taxidermy or mounting, things can go wrong if the beetles are not properly cared for, leading to mold, decay, or uneven drying. This can result in a poorly preserved specimen. Incorrect beetle selection can also lead to suboptimal results.

Beetle Selection and Caring

When choosing beetles for European mounts, it’s essential to select the right species. For example, the species Dermestes maculatus is commonly used for drying and preserving small game such as rabbits and squirrels. These beetles can be kept at a temperature between 65-70°F (18-21°C) and 60-70% humidity, and the substrate should be kept dry to prevent mold growth. The beetles should be fed a diet of dried blood, bone meal, or commercial beetle food.

Mount Preparation and Beetle Application

Before applying the beetles, the mount should be prepared by removing any loose skin, flesh, or other debris. This will help the beetles to work more efficiently and prevent the spread of bacteria or mold. The beetles should be applied evenly to the mount, covering all areas that need to be dried or preserved. The beetles will typically take 2-6 weeks to complete their work, depending on the size of the mount and the temperature and humidity levels.

Troubleshooting Common Issues

If problems arise during the beetle-aided drying process, it’s essential to identify the cause and take corrective action. For example, if mold appears, the substrate may be too wet or the beetles may not be working efficiently. In this case, the beetles should be removed, and the mount should be dried further to prevent the spread of mold. Regular monitoring and maintenance are crucial to ensure the success of the beetle-aided drying process.
