Three effective DIY rat baits include mixing equal parts baking soda and peanut butter to create a toxic paste, combining plaster of Paris with cornmeal and milk to form lethal dough balls, or using instant potato flakes mixed with peanut butter to cause fatal dehydration. Place these homemade baits near entry points or areas with rat activity, and monitor regularly. Keep them away from pets and children. These simple kitchen ingredients offer economical solutions to your rodent problems.
Baking Soda and Peanut Butter Mixture

When looking for an effective homemade rat bait, you’ll find that combining baking soda with peanut butter creates a particularly potent solution.
This simple rat control solution works because the peanut butter’s aroma attracts rodents while the baking soda acts as a homemade rat poison once ingested.
To prepare this bait, mix equal parts baking soda and peanut butter until well-combined. The resulting paste should maintain the appealing scent that rats find irresistible.
Place small amounts in secure containers near rat activity areas—behind appliances, in corners, or outdoor hiding spots.
When rats consume this mixture, the baking soda reacts with stomach acids, producing carbon dioxide they can’t expel.
Remember that rats can be cautious eaters, so position multiple bait stations to increase your chances of success.
Plaster of Paris and Cornmeal Formula
Resourceful homeowners can create an equally effective rat bait by combining plaster of Paris with cornmeal. This homemade rat bait uses equal parts of each ingredient, mixed with just enough milk to form a soft, pliable dough.
Roll this mixture into marble-sized balls and let them dry slightly before placement. Position these baits in areas with high rat activity—near entry points or suspected nesting locations.
The formula works because rats find the cornmeal irresistible, but once ingested, the plaster of Paris expands in their digestive system, leading to their demise.
Monitor your bait stations regularly during a rat infestation, replacing any consumed or stale balls. This method is particularly valuable because it remains non-toxic to pets and humans while effectively targeting rats.
Instant Potato Flakes Dehydration Method

Among the simplest homemade rat control methods, instant potato flakes offer a surprisingly effective solution. When mixed with peanut butter as an attractant, they create a powerful homemade rat poison that’s both economical and accessible.
The science behind this method is straightforward: once consumed, the potato flakes absorb moisture in the rat’s stomach, expanding considerably and causing fatal distress when eaten in sufficient quantities.
For best results, place your peanut butter and potato flake mixture in areas where you’ve noticed rat activity—look for droppings or gnaw marks as indicators.
Don’t forget to monitor these bait stations regularly, replenishing as needed to maintain effectiveness.
This approach gives you a practical way to address rat problems using common household ingredients you likely already have in your pantry.
