1. **Wood**: Use untreated wood, as treated wood can be harmful to hedgehogs. Plywood or cedar is a good choice. Make sure the wood is thick enough to provide insulation and protection from the elements.
2. **Insulation**: To keep the house warm, especially in colder climates, consider using insulation materials like straw or hay inside the walls. This will help maintain a stable temperature.
3. **Roofing Material**: A waterproof roof is essential. You can use shingles or metal sheets to protect the house from rain and snow. Ensure that the roof overhangs a bit to direct water away from the entrance.
4. **Entrance**: Cut a small entrance hole (about 4-6 inches in diameter) that is low to the ground. This makes it easier for hedgehogs to enter and exit.
5. **Flooring**: A solid floor is important to prevent moisture from seeping in. You can use plywood or wooden planks, but ensure there's enough drainage if the house is on grass.
6. **Ventilation**: While insulation is important, so is proper ventilation. Make small holes near the roof to allow air circulation without letting in drafts.
7. **Sealing Materials**: Use non-toxic sealants to protect the joints of the house from moisture and pests. Avoid any chemicals that could harm hedgehogs.
8. **Decoration**: While not necessary, you can add a small sign or decoration to make the house more inviting, but ensure it doesn’t compromise safety.
By using these materials, you can create a cozy and safe haven for hedgehogs in your garden or backyard. Remember to place the house in a quiet, sheltered area away from predators and direct sunlight.
