Quick Answer
Humanure composting can attract pests or animals if not properly managed. However, with adequate techniques and materials, these risks can be minimized. Proper humanure composting typically involves using a secure, covered composting system and incorporating adequate carbon-rich materials to achieve optimal decomposition.
Choosing the Right Composting System
When selecting a humanure composting system, it’s essential to choose one that is designed to minimize the risk of attracting pests or animals. Look for a system with a secure lid or enclosure that can be easily locked or covered. For example, a 3x3x3 foot (0.9x0.9x0.9 meters) worm composting system with a secure lid and 1-2 inches (2.5-5 cm) of gravel or sand at the bottom can help deter pests. This type of system can process up to 10 pounds (4.5 kg) of humanure per week.
Incorporating Carbon-Rich Materials
Incorporating sufficient carbon-rich materials into the composting process can help absorb excess moisture, reduce odors, and minimize the risk of attracting pests. Aim to add 2/3 to 3/4 carbon-rich materials (such as coconut coir, shredded newspaper, or cardboard) to 1/3 to 1/4 humanure, based on weight. For example, adding 5 pounds (2.3 kg) of coconut coir to 2 pounds (0.9 kg) of humanure can help create a balance and reduce the risk of attracting pests.
Maintaining Proper Composting Conditions
Maintaining optimal composting conditions, including adequate aeration, moisture, and temperature, is crucial for minimizing the risk of attracting pests. Regularly turning the compost pile and ensuring adequate aeration can help prevent anaerobic conditions that may attract pests. Additionally, maintaining a temperature range of 130-140°F (54-60°C) within the composting system can help kill pathogens and weed seeds, reducing the risk of attracting pests.
