Mosquitoes place eggs in still water. such as found in a cistern.
Mosquitoes are a familiar flying nuisance, and they need still water to lay their eggs. Since many species also carry disease, preventing standing water for them to use can drastically reduce this risk around the home. Landscape cisterns, used to hold rainwater for property use, can offer the ideal breeding place for mosquitoes. There are several steps that can be taken to prevent the cistern from becoming a mosquito breeding tank. Does this Spark an idea?
Instructions
1. Change or use the water in the cistern once a week. Be sure the container is empty and completely dry. Mosquito eggs and larvae can survive in tiny amounts of water.
2. Use a tight-fitting cover to prevent the mosquitoes from gaining access to the water. Add a small amount of cooking oil to cover the water surface if the lid is not tight, was left off, or if mosquitoes have found a way in.
3. Add the bacillus known as Bt to the water. This bacteria is harmless to animals. Follow the product label instructions for application rates.
4. Keep mosquito fish in the cistern if you are familiar with keeping fish as pets. These fish eat mosquito larvae, but will need care and proper water parameters. Fish are the most complicated method of mosquito prevention.
