The key lies in uncooked rice, which becomes a potent bait when mixed with plaster powder (also referred to as white cement or lime). This mixture is deadly to both rodents and cockroaches when consumed.
To prepare this homemade pest control solution:
Mix equal parts of finely ground raw rice and plaster powder.
Distribute the mixture into small containers or bottle caps.
Place these traps in strategic locations such as under sinks, behind furniture, in dark corners, or near drain openings—where pests are likely to travel.
