Signs You Have Rats in the Garage

If you suspect that you have rats in your garage, there are several telltale signs to look out for. By identifying these signs early on, you can take the necessary steps to get rid of the rats and prevent any further damage.

Here are some common signs that indicate the presence of rats in your garage:

Droppings and Urine Stains

Finding rat droppings and urine stains in your garage is a clear indication of a rat infestation. Rat droppings are typically small, dark, and resemble grains of rice. You may find them scattered in corners, along baseboards, or near food sources.

Additionally, you may notice urine stains, which can appear as small, dark smudges on surfaces.

Chewing Damage

Rats have strong teeth that continuously grow, so they need to gnaw on objects to keep them trimmed. As a result, you may find chew marks on various items in your garage. Look for gnawed wires, wood, insulation, or even plastic containers.

These signs of chewing can indicate that rats are present and actively causing damage.


Rats are known to create burrows in hidden areas of your garage, such as behind stored items or in piles of clutter. These burrows serve as their nests and provide them with a safe place to breed and raise their young.

Keep an eye out for small holes or tunnels in the corners or along the walls of your garage.

Seeing Live or Dead Rats

If you spot a live or dead rat in your garage, it’s a clear indication that there is an infestation. Rats are nocturnal creatures, so they are more likely to be seen during the night. However, if you notice them during the day, it could be a sign of a larger rat population.


Rats are known to be active and noisy creatures. If you hear scratching, scurrying, or squeaking sounds coming from your garage, it’s a strong indication that rats are present. These noises are usually more prominent during the night when rats are most active.

Remember, if you notice any of these signs in your garage, it’s important to take immediate action to eliminate the rat infestation. Rats can cause significant damage to your property and pose health risks, so it’s best to address the problem as soon as possible.

Why It’s Important to Get Rid of Rats

Rats are not only a nuisance but also pose several risks to both your property and health. Here are a few reasons why it is crucial to eliminate rats from your garage:

Damage to Belongings

Rats have a gnawing instinct, and they can cause significant damage to your belongings stored in the garage. They can chew through electrical wires, insulation, and even wooden structures. This can lead to potential fire hazards and costly repairs.

Disease Risks

Rats are known carriers of various diseases that can be transmitted to humans. They can contaminate food, surfaces, and utensils with their urine, droppings, and saliva. Diseases such as leptospirosis, hantavirus, and salmonellosis are just a few examples of the health risks associated with rat infestations.

According to the Centers for Disease Control and Prevention (CDC), rats can also transmit diseases indirectly through fleas, ticks, and mites that infest them. These pests can bite humans and transmit diseases such as Lyme disease and typhus.

Reproduction Rate

Rats are notorious for their rapid reproduction rate. A single female rat can produce up to 12 litters per year, with each litter consisting of 6-12 pups. This means that a small rat problem can quickly escalate into a full-blown infestation if not addressed promptly.

According to a study by the University of California Agriculture and Natural Resources, a pair of rats can potentially produce up to 2,000 descendants in a year if left unchecked. This exponential growth can lead to an overwhelming rat population in your garage and surrounding areas.

Can Attract Other Pests

Rats can attract other pests to your garage. Their presence and the scent of their urine can lure in other rodents, such as mice, as well as insects like cockroaches and flies. This can create a domino effect, where multiple pests infest your garage, making it even more challenging to eradicate the problem.

It’s essential to address rat infestations promptly to prevent the attraction of additional pests and mitigate any further damage to your property.

Tips for Getting Rid of Rats in the Garage

Set Traps

One effective way to get rid of rats in the garage is by setting traps. Snap traps are commonly used and can be baited with peanut butter or pieces of cheese. Place the traps near areas where you have seen rat droppings or signs of activity. Check the traps regularly and dispose of any captured rats.

Use Rodenticide Poisons

If the rat infestation in your garage is severe, you may consider using rodenticide poisons. These poisons are designed to kill rats and should be used with caution. It is important to follow the instructions provided by the manufacturer and keep them out of reach of children and pets.

Remember to dispose of any dead rats properly.

Use Natural Rodent Deterrents

If you prefer a more natural approach, there are several deterrents that can help keep rats away from your garage. Peppermint oil, for example, has a strong scent that rats dislike. Soaking cotton balls in peppermint oil and placing them around the garage can help deter rats.

Another natural deterrent is the use of ultrasonic devices that emit high-frequency sounds that rats find irritating.

Seal Up Entry Points

Rats can squeeze through small openings, so it’s important to seal up any potential entry points in your garage. Inspect the walls, doors, and windows for gaps or cracks and use caulk or steel wool to seal them.

Pay attention to areas where pipes or wires enter the garage, as rats can use these as access points as well.

Clean Up Clutter and Food Sources

Rats are attracted to clutter and food sources, so keeping your garage clean and organized can help prevent infestations. Remove any piles of debris or clutter that may serve as hiding spots for rats. Additionally, make sure to store any food or pet food in sealed containers to eliminate potential food sources for rats.

Get a Cat

Having a cat in your garage can be an effective deterrent against rats. Cats are natural predators and their presence alone can discourage rats from entering your garage. If you’re considering getting a cat specifically for rodent control, make sure to choose a breed known for its hunting skills.

By implementing these tips, you can effectively get rid of rats in your garage and prevent future infestations. Remember to always prioritize safety when using traps or poisons, and consider consulting with a professional pest control service if the infestation persists.


Having rats invade your garage can be stressful and frustrating. However, with consistent trapping, sealing up entryways, removing food sources, and implementing natural deterrents, you can get rid of your rodent problem for good.

Be vigilant in keeping rats out by maintaining a clean garage free of clutter and available food. Take action at the first signs of a rat infestation to prevent extensive damage. With time and effort, you can safely evict rats from your garage and prevent future invasions.

We hope this comprehensive guide gives you plenty of tips for ridding your garage of rats successfully. Don’t hesitate to contact a pest control professional if the infestation persists despite your best efforts. They have industrial-strength solutions for stubborn rat problems.

You’ll be able to use and enjoy your garage again once the rats are gone.
