Rodents 5

Rats can be an unwelcome and persistent problem for homeowners. They can cause property damage, spread diseases, and are generally unpleasant to deal with. One common question people often ask is, “What can I spray to keep rats away?” In this comprehensive guide, we’ll explore various commercial and homemade rat repellent sprays, their ingredients, and their effectiveness.


You can use commercial rat repellent sprays such as Tomcat Rodent Repellent, Grandpa Gus’s Rodent Repellent Spray, or Exterminator’s Choice Mice Defense Spray to keep rats away. These sprays contain natural ingredients like essential oils that repel rodents. Alternatively, you can make a homemade rat repellent spray using ingredients like peppermint oil, vinegar, and spices. However, remember that these sprays may not be a permanent solution for a severe infestation, and professional pest control may be necessary.

Several commercial rat repellent sprays are available on the market. Some popular options include:

  1. Tomcat Rodent Repellent
  2. Grandpa Gus’s Rodent Repellent Spray

  5. GreenGro Rodent Repellent

These sprays typically contain natural ingredients like peppermint oil, cinnamon oil, and other essential oils that are known to repel rodents.

How Do These Sprays Work?

Rat repellent sprays work by using naturally occurring substances and essential oils that create an unpleasant smell or taste for rats. These ingredients work by making rodents wary of the new smell in the area, as they are constantly trying to keep themselves safe from predators.

Making Homemade Rat Repellent Spray

If you prefer a DIY approach, you can make your own homemade rat repellent spray using ingredients like essential oils, vinegar, and spices. Here are a few recipes you can try:

Peppermint Oil Spray – 1 cup of water or rubbing alcohol – 2 teaspoons of peppermint oil – Spray bottle

Garlic, Castor Oil, and Tabasco Spray – Minced garlic cloves – Castor oil – Soap – Tabasco sauce – Water – Spray bottle

Safety Measures

While these sprays can help deter rats, it’s important to consider their safety around children, pets, and wildlife. Always follow the specific instructions on the product label and consider the context in which the spray is being used to ensure safety.

Frequency of Use

The optimal frequency of using these sprays depends on the type of spray and its purpose. For example, for a homemade essential oil spray, you may need to reapply it every week to maintain its effectiveness.

Where to Purchase

Rat repellent sprays can be purchased from various retailers, both online and in-store. Some popular online retailers include Amazon, The Home Depot, Walmart, and Lowe’s. The cost of these sprays varies depending on the brand and size.


While rat repellent sprays can be an effective tool in deterring rats, they may not be a permanent solution for a severe infestation. In such cases, it’s best to consult a professional pest control service. Remember, the most effective rodent repellent method is cleanliness, as rodents are scavengers and will consume any available food.
