Borax For Rats: A Guide with Borax Rat Poison Recipes

It is important to note that while borax can be effective in killing rats, it may not be the most humane or recommended method of rat control. There are other options available, such as using live traps or calling professional pest control services, which can ensure a more humane approach to dealing with rat infestations.

Understanding the Effectiveness of Borax on Rats

Scientific research has shown that borax has potent poison properties that can be lethal to rats. A study documented in the Journal of Economic Entomology revealed that pure borax is highly toxic to both adult rats and their offspring. The study also found that a combination of borax and sugar was exceptionally effective in luring rats, surpassing other bait options like peanut butter or cheese.

Another investigation published in the Journal of Applied Toxicology evaluated the rat-killing potential of borax through feeding trials. The findings indicated that a mixture of borax and cornmeal proved remarkably effective in eliminating rats, with a significantly lower lethal dose compared to other rat poisons available on the market.

While these studies suggest that borax can be effective in killing rats, it is essential to consider the potential risks and drawbacks associated with using borax as a rat poison.

Potential Risks and Drawbacks of Using Borax for Rat Control

1. Environmental Impact: Borax can have detrimental effects on the environment. When borax is released into the soil or water, it can contaminate the ecosystem and harm other animals or plants.

2. Health Risks: Borax can also pose health risks to humans and pets. Ingesting or inhaling borax can lead to various health issues, including respiratory problems, skin irritation, and gastrointestinal distress.

3. Slow Killing Process: Using borax to kill rats may not provide immediate results. It can take several days or even weeks for the poison to take effect, during which time rats may continue to reproduce and cause damage to your property.

4. Inhumane Method: While some may argue that any method of rat control is justified, using borax to kill rats can be considered inhumane. Rats may suffer while dying, and there is a risk of secondary poisoning if other animals consume the poisoned rats.

Given these potential risks and drawbacks, it is essential to consider alternative methods of rat control before resorting to using borax as a rat poison.

Humane Alternatives for Rat Control

1. Live Traps: Live traps are an effective and humane way to capture rats without causing harm. Once trapped, rats can be safely released in a remote area away from residential areas.

2. Pest Control Services: Calling professional pest control services can provide effective rat control solutions. These experts have the knowledge and tools to safely remove rats from your property using humane methods.

3. Prevention Methods: Taking preventive measures can significantly reduce the risk of rat infestations. Seal any cracks or openings in your home, eliminate potential food sources, and keep your surroundings clean and tidy.

4. Natural Repellents: Natural repellents such as peppermint oil, vinegar, or ammonia can deter rats from entering your home. Place these repellents near possible entry points or areas where rats are known to frequent.

5. Ultrasonic Devices: Ultrasonic devices emit high-frequency sound waves that are unpleasant to rats and can deter them from entering your home. These devices are safe for humans and pets.


While borax may be effective in killing rats, it is crucial to consider the potential risks and drawbacks associated with its use. There are alternative methods available that provide more humane and environmentally friendly approaches to rat control. Live traps, professional pest control services, prevention methods, natural repellents, and ultrasonic devices are all viable options to consider. It is advisable to weigh the pros and cons of each method and choose the most suitable approach for your specific situation.
