Management and cultural practices
- Clean dikes and main irrigation canals, including surrounding areas, and free them of weeds.
- Reduce the size of the bunds or dikes (less than 30 x 30 cm) as rats prefer to nest on the higher ground of the rice field. It limits the nesting and burrowing sites and the areas for weeds to grow.
- Cover burrows and place the treated baits.
- To drive out rats in their burrows and nesting sites, flood the
paddies just below the dike level. This practice will not kill them but force them to go to a higher ground.
- Follow synchronous planting, i.e., planting at the same time with other farmers in the same area.
- Completely remove rice straws after harvest.
- Fallow the rice field 1 - 2 months during the dry season.
- When possible, do not kill mongoose, snakes, owls and other birds as they are very good predators of rats.
- Always remember that rat control can be best achieved if most of the rice farmers act together to limit the factors that favor rat population build-up, such as food and shelter.
