Mosquitoes can breed in even the smallest amount of standing water, posing serious health risks. Rainwater harvesting systems are particularly vulnerable if not properly protected. Fortunately, preventing mosquitoes from entering and breeding in your system is simple with the right components and practices.

Six Steps to Mosquito-Proof Your Rainwater System
1.**Eliminate Standing Water** β Empty or change any water-holding containers around your home at least weekly.
2. **Use First Flush Diverters** β Install a First Flush Diverter to remove the initial runoff that may contain mosquito larvae and roof contaminants.
3. **Install Leaf Eaters** β Use downspout filters like Leaf Eaters to block debris and reduce insect breeding areas.
4. **Fit Mozzie Stoppa Valves** β These stainless steel mesh valves prevent mosquitoes and pests from entering tank overflows.
5. **Ensure Proper Airflow** β Devices like the Mozzie Stoppa allow air to flow across stored water, raising oxygen levels and improving water quality.
6. **Seal All Inlets and Outlets** β Block access to all entry points using appropriate screens or flaps.
