A mixture of peanut butter and baking soda is a popular but unreliable and potentially inhumane home remedy intended to kill rats by causing fatal gas buildup in their digestive system.
While the theory behind using peanut butter and baking soda to kill mice is popular online, it is not a reliable or effective method. It is also not a humane solution and can lead to a prolonged and painful death for the rodent. Here is a breakdown of why this method is ineffective: Mice can burp.
Baking soda is not toxic. It is not a poison. If rats consume a VERY large amount of baking soda all at once, it can react with their stomach acids and create gas. Because rats can't burp, too much gas all at once can cause the stomach to rupture.
Devices like snap traps or spring traps kill mice or rats with mechanical action, and there are also traps that kill with an electric shock. Glue traps hold the animal in place for extermination and disposal.
What Smell do House Rats Hate?
Food to avoid
Phosphides are rather fast-acting rat poisons, resulting in the rats dying usually in open areas, instead of in the affected buildings. Phosphides used as rodenticides include: aluminium phosphide (fumigant and bait) calcium phosphide (fumigant only)
The fatty nature of any nut butter is very enticing to rats. More specifically, get some peanut butter and use that as rat bait, as it is one of their favorite food items to nibble on.
Baking Soda for Short-Term Relief
Baking soda (sodium bicarbonate) is an alkaline chemical compound. 1 Because it's alkaline, baking soda can be used to relieve heartburn by neutralizing excess stomach acid in the same way antacids do. Relief can occur anywhere from minutes to hours after taking baking soda.
7 Natural Repellents to Get Rid of Rats
Rats and mice have similar diets, so their traps can be baited similarly. As with mice, peanut butter and hazelnut spread are the best options for rat traps.
Camphor/Mothballs
These contain naphthalene, which release a scent that is disliked by rats.
Look for signs of rat or mouse infestation: Rodent droppings around food packages, in drawers or cupboards, and under the sink. Nesting material such as shredded paper, fabric, or dried plant matter. Signs of chewing on food packaging.
Regardless of if you're dealing with a vegetarian or an omnivore, however, food with strong smells — nuts, fish, or moldy cheese — are best at luring rats into traps. Check out our baiting guides for brown and black rats.
Most general purpose disinfectants and household detergents are effective for this. A mixture of 1 part bleach and 10 parts water can also be used.
Learn about mice and their top predators in the wild and in urban environments.
Critter Control professionals use industry-standard traps, exclusion techniques, and damage repair to safely and effectively remove rats from your home. We identify entry points, seal access, and implement deterrents to prevent future infestations. We find nests, entry points, and signs of activity.
Rats and mice are nocturnal with most activity taking place between approximately one half hour after sunset to about one half hour before sunrise. Garbage is an excellent food source for rodents. Store garbage and rubbish in rodent-proof containers.
Chocolate. Never give chocolate to your pet. It contains a powerful stimulant called theobromine (similar to caffeine), which is poisonous to rodents. Dark chocolate and cocoa contain high levels of theobromine.
Birds of prey are famous for feeding on rodents. Hawks and falcons hunt by day, and owls typically hunt by night. Owls are especially dangerous to rats because they hunt at the same time that rats forage for food. The Red-tailed Hawk (Buteo jamaicenis) is North America's most familiar and widespread large hawk.
