5 Effective Methods for How to Keep Cats Out of Garage

Here are five effective methods you can use to keep cats out of your garage:

Method 1: Keep the Garage Door Closed at All Times

The simplest and most effective way to prevent cats from accessing your garage is to keep the garage door closed at all times. Cats are curious and opportunistic animals, and they can sneak in when the door is open or not fully closed. Once they are in, they might find a cozy spot to hide or sleep, and you might not even notice them until it’s too late.

To avoid this scenario, you should establish a habit of closing the door consistently and securely. Here are some tips on how to do that:

  1. Use a remote control, a timer, or a sensor to close the door automatically after you enter or exit the garage.
  2. Check the door before you leave the house or go to bed, and make sure it is fully closed and locked.
  3. Install a garage door monitor or alarm that alerts you if the door is open or tampered with.
  4. Repair any damages or malfunctions that might prevent the door from closing properly.

Keeping the garage door closed has many benefits besides keeping cats out. It can also save energy, prevent theft, and maintain a clean and organized space.

Method 2: Use Natural Repellents to Deter Cats from Entering the Garage

Another method to keep cats out of your garage is to use natural repellents that deter them from entering the garage using smells and tastes. Cats have a keen sense of smell and taste, and they are sensitive to certain scents and flavors that humans find harmless or pleasant. These scents and flavors can irritate or mask the cat’s senses, making them avoid the area.

Use Natural Repellents

Some examples of natural repellents that you can use are:

  1. Coffee grounds: Cats dislike the smell of coffee, and coffee grounds can also act as a fertilizer for your plants
  2. Citrus peels: Cats hate the smell of citrus fruits, such as oranges, lemons, limes, or grapefruits
  3. Vinegar: Cats detest the smell and taste of vinegar, and vinegar can also help remove cat urine odor
  4. Cayenne pepper: Cats abhor the smell and taste of cayenne pepper, and cayenne pepper can also repel other pests
  5. Mothballs: Cats loathe the smell of mothballs, and mothballs can also protect your clothes from moths

To use these repellents effectively, you should follow these instructions:

  1. Sprinkle, spray, or hang them in bags or containers around the garage perimeter or entrance
  2. Replace them regularly as they lose their potency over time
  3. Keep them out of reach of children and pets, as they can be harmful if ingested
  4. Avoid contact with eyes or skin, as they can cause irritation or allergic reactions

Using natural repellents is a cheap and eco-friendly way to keep cats out of your garage. However, they might not work for all cats or in all situations. Some cats might be more tolerant or indifferent to these scents or flavors, or they might get used to them over time. Also, these repellents might not be enough to stop a hungry or desperate cat from entering your garage.

Method 3: Employ Noise Oscillators and Motion-Activated Sprinklers

If natural repellents are not enough to keep cats out of your garage, you might want to try some more advanced devices that deter them from using sound or water. Noise oscillators and motion-activated sprinklers are devices that create an unpleasant or startling environment for cats using sound or water. These devices can scare away cats without hurting them or damaging your property.

Devices Can Scare Away Cats

Some examples of noise oscillators and motion-activated sprinklers that are suitable for garages are:

  1. PetSafe Indoor Radio Fence: This device emits a high-pitched sound that only cats can hear when they approach a designated area. You can use it to create a boundary around your garage door or inside your garage.
  2. Orbit Yard Enforcer: This device sprays a jet of water when it detects motion within a 40-foot range. You can use it to cover your garage entrance or the area around your garage.
  3. Safer Brand Critter Ridder: This device combines sound and water to repel cats and other pests. It emits a loud noise and flashes a light when it senses motion, and it also sprays a stream of water that contains black pepper oil and capsaicin, which irritate the cat’s skin and eyes.

To use these devices effectively, you should follow these instructions:

  1. Choose a location that covers the area you want to protect, such as the garage door or the garage perimeter
  2. Set the frequency or range of the device according to your preference and need
  3. Test the device before use to make sure it works properly and does not harm any plants or animals
  4. Check the device regularly and replace the batteries or water as needed

Using noise oscillators and motion-activated sprinklers is a humane and effective way to keep cats out of your garage. However, they might also have some drawbacks, such as being expensive, noisy, or wasteful. Also, these devices might not work in extreme weather conditions, such as rain, snow, or wind.

Method 4: Utilize Kitty Litter to Indicate Occupancy

Another method to keep cats out of your garage is to utilize kitty litter to indicate occupancy. This method works by mimicking the scent of another cat’s territory, which can make cats feel unwelcome or threatened. Cats are territorial animals, and they usually avoid areas that are already claimed by another cat. By placing kitty litter in your garage, you can create a psychological barrier for cats that prevents them from settling in your garage.

Create a Psychological Barrier for Cats

To use this method effectively, you should follow these tips:

  1. Choose a brand of kitty litter that has a strong odor, such as clumping or scented kitty litter.
  2. Place kitty litter in strategic spots in your garage, such as near potential entrances or hiding spots.
  3. Replace kitty litter regularly as it loses its scent or gets dirty.

Using kitty litter is a simple and clever way to keep cats out of your garage. However, it might also have some drawbacks, such as being messy, smelly, or attractive to other animals or insects. Also, this method might contradict the other methods that aim to remove cat scents from your garage.

Method 5: Seal All Entrances and Regularly Clean the Garage

The final and most important method to keep cats out of your garage is to seal all entrances and regularly clean the garage. This method works by eliminating any possible ways for cats to enter your garage and removing any appealing scents that might attract them. Cats can find their way in through gaps, holes, or cracks in your garage walls, roof, or door. Once they are in, they might be attracted by food scraps, trash cans, or their urine or feces.

To use this method effectively, you should follow these steps:

  1. Identify and seal any openings in your garage using materials like caulk, mesh wire, wood panels, or insulation foam
  2. Clean your garage thoroughly and remove any traces of cat urine, feces, or food using products like baking soda, Panther Armor Anti-Cat Scratch Tape, Sentry Stop That! spray, Pet Mastermind Claw Withdrawal Cat Spray, Sofisti Cat Scratch Deterrent Tape, or Stelucca Shields
  3. Keep your garage tidy and organized and avoid leaving any items that might tempt cats, such as blankets, pillows, toys, or cardboard boxes

Sealing all entrances and regularly cleaning the garage is the best way to keep cats out of your garage permanently. It can also improve the appearance and functionality of your garage and prevent other problems like mold, pests, or fire hazards.

Additional 3 Tips and Considerations for How to Keep Cats Out of Garage

If none of these methods work for you or if you encounter a feral or stray cat that needs help, here are some additional tips and considerations that you can try:

  1. Contacting No-Kill Shelters or using TNR (Trap-Neuter-Return) programs if necessary to humanely deal with feral or stray cats. You can find local organizations or groups that offer these services online or by asking around. These services can help you trap, neuter, vaccinate, and return the cats to their original location or find them a new home.
  2. Offering alternative shelters to divert cats away from your garage. You can provide some simple shelters for cats using cardboard boxes, straw bales, or cat houses. You can place them in a safe and sheltered spot away from your garage and make them comfortable and warm for cats. This way, you can help the cats without letting them into your garage.
  3. Using commercial repellent sprays as a last resort. If all else fails, you can try using some commercial repellent sprays that are designed to keep cats away from certain areas or surfaces. Some examples are Four Paws Keep Off! Spray, PetSafe Ssscat Spray, Colton’s Naturals, or Homarden Scat Mat. These sprays use different ingredients or mechanisms to repel cats, such as essential oils, pheromones, or motion sensors. However, you should use these sprays with caution and follow their proper usage instructions. Some of these sprays might be harmful to cats or humans if ingested or inhaled, or they might damage your furniture or plants. Also, these sprays might not work for all cats or in all situations, and they might lose their effectiveness over time.
