Eliminating rats and cockroaches naturally is possible with simple, household ingredients—most notably, raw rice and plaster (also known as white cement or lime). This eco-friendly and cost-effective remedy avoids harmful chemicals, making it safer for homes with children and pets (when applied cautiously). The method involves mixing equal parts of finely ground dry rice and powdered plaster. This blend is then placed in small containers, such as bottle caps, and strategically positioned in pest-prone areas like corners, under furniture, and near drains.

What makes this method effective is the reaction that occurs after pests ingest the mixture and drink water—ideally provided nearby in a small dish. The water causes the plaster to harden inside the rodent or cockroach’s stomach, leading to a fatal outcome. Rice is appealing due to its neutral scent and taste, and grinding it ensures that even small pests can consume it easily. Although results aren’t instant, this method typically shows effects within 2 to 5 days, depending on infestation levels. For best results, repeat the treatment weekly for about a month. Additionally, maintain cleanliness, seal entry points, and store food securely to prevent reinfestation. This natural approach provides a reliable and affordable alternative to chemical pesticides, offering peace of mind while effectively addressing the problem.
