Understanding Why Mice are Attracted to Your Office

Mice are attracted to your office for various reasons. Shelter is a primary attraction, as your office provides protection from the cold weather and predators. They find the perfect hideout and can avoid any potential harm.

Having a continuous supply of food is also a significant factor. You may notice that mice are quite resourceful creatures, and they can easily find leftover bits of food in office spaces, including desk drawers, break areas, and even in the waste bins! One could consider your office a mice buffet paradise, and it is this abundance of nourishment that holds mice to your workspace.

In addition to food and shelter, mice are naturally drawn to areas with constant warmth. Offices often have heating systems that run throughout the day, providing a comfortable and cozy environment. This makes offices a prime real estate for the little critters, especially during the colder months.

Now that you understand the primary reasons mice find your office attractive, it will make it easier to design a plan to keep them away from your workspace. Before we dive any further, let’s discuss how you can detect and identify mice activity in your office.

Identifying Mouse Infestations in The Workplace

Detecting Mouse Droppings

One telltale sign of a mouse infestation in your office is the presence of mouse droppings. These small, dark pellets are often found around food sources, in drawers, or under desks. To help differentiate between mice droppings and those of other pests, note that mice droppings are typically about 1/4 inch in length, and have pointed ends. Keep an eye out for such droppings, as that’s a clear indicator of unwanted rodent presence.

Locating Gnawed Wires

Mice have a penchant for gnawing on wires, which is not only dangerous for your office’s electrical system but also for the mice themselves! If you notice wires with gnaw marks or even frayed cables, it could point towards a mouse infestation. Mice use their sharp teeth to nibble on wires, seeking both warmth and to sharpen their ever-growing teeth.

Examples of common places to find gnawed wires are:

  • Behind computers or other office equipment
  • Along the baseboards
  • In the walls near electrical outlets

Noticing Damages to Walls and Structures

Mice are notorious for causing damage to walls and other structures as they scavenge for food and nest-building materials. Watch out for small, irregular-shaped holes in walls and baseboards, which serve as entry points for these rodents. Signs of a mouse infestation can include:

  • Holes chewed through walls or floors
  • Scratching or scuffling sounds coming from behind walls or under the floorboards
  • Piles of nesting materials like shredded paper, insulation, fabric, or dried plant matter
  • Evidence of chewed packaging or food containers

By keeping a vigilant eye on your office and recognizing these signs of a mouse infestation, you’ll be able to take prompt action in preventing further damage and ensuring a rodent-free working environment.

How To Keep Mice Out Of Your Office

1. Use of Essential Oils

Peppermint oil and clove oil are both effective essential oils known to deter mice. In fact, Cornell University notes that peppermint oil can be used as an effective vertebrate repellent. Using these oils is an all-natural way to keep these rodents at bay!

You can try spraying the oils around your office, paying special attention to known entry points like gaps near doors, windows, and walls. Don’t go too heavy on the oil. Dilute it by combining 20 drops of peppermint oil with 2 cups of water. Then, a light mist should be enough to do the trick. Just be sure to reapply as needed!

You can also try using a commercial peppermint oil repellent product. We recommend Mighty Mint Rodent Repellent which is all natural and uses peppermint oil as the main ingredient.

2. Sealing Entry Points

In order to keep mice from invading your office in the first place, it’s essential to focus on sealing entry points. Mice can easily enter through small gaps like those found around pipes, wires, and vents. Spending a bit of time inspecting your office and sealing these access points can save you from a possible infestation.

Some common materials you can use to seal these gaps include caulk, spray foam, or steel wool. By taking this step, you’re essentially putting up a VIP “no entry” sign for uninvited furry visitors!

3. Proper Food Storage

Keeping mice out isn’t only about sealing cracks and using essential oils; it’s also vital to practice proper food storage. Mice are always on the lookout for an easy meal, and leaving food out in the office can be a veritable five-star buffet to them!

To avoid this situation, store food in airtight containers made of glass or metal rather than plastic containers, which mice can easily chew through. This includes snacks, sugar, and even coffee creamer. If you have an office pantry, make sure that all food items are properly stored and organized, and that trash is disposed of regularly. With these steps, you’ll prevent those pesky rodents from considering your office as their very own Michelin-starred dining experience.

4. Hiring a Pest Control Company

When it comes to keeping mice out of your office, sometimes natural methods just don’t cut it. In these cases, professional pest control can be a lifesaver! Not only do pest control companies have access to powerful tools and treatments, but they also have the expertise to tackle the problem head-on.

You don’t need a Ph.D. in mice-ology to erase these furry intruders from your workspace. With a professional pest control company by your side, you can trust that they have done the research and can implement the most effective strategies for mouse eradication.

However, with so many options out there, choosing the right pest control company might seem overwhelming. Here are a few tips to help you make an educated decision:

  1. Credentials: Make sure the company has the necessary licenses and certifications. You want a company that meets industry standards and follows regulations.
  2. Reputation: Look for reviews and testimonials from previous clients. A good pest control company should have a strong track record of satisfied customers.
  3. Experience: The longer a company has been in business, the more likely they are to have encountered (and solved) all kinds of rodent problems.

By selecting a reputable pest control company, you’re taking a significant step towards a mouse-free office. Once they’ve assessed your situation, these professionals will typically seal any entry points, remove any existing mice, and help prevent future infestations.

Plus, hiring a professional pest control company means that you can focus on your work instead of mouse-proofing your office. If you’re looking for a pest control professional, check out our pest control locator tool to find help near you!

Mice infestation in your office can be both annoying and frustrating. But fear not, there are ways to deal with these small invaders without causing them harm. You’re in luck, as we’ll focus on one of the most effective yet humane methods: the use of humane traps.

How To Use Humane Traps Against Mice In the Office

Live-catch traps provide the best option to remove mice from your office without resorting to harmful methods. These traps allow you to relocate the caught mice a safe distance away. Let’s dive into some specific considerations to make when using humane traps:

PlacementMice are known to follow walls and corners—so be sure to place your traps accordingly. The more strategic your placement, the better your chances are of catching these persistent pests!
BaitEnticing the mice is crucial for the success of your traps. Some popular, office-friendly bait options include peanut butter, fruit, cheese, and nuts. Be sure to place a small amount of bait in the trap to avoid unintentional free meals for the mice.
Regular checksTo ensure the humane treatment of the captured mice, it’s important to check your traps frequently. Prompt release prevents unnecessary stress for the critters and ensures they don’t suffer in the traps for too long.
RelocationWhen releasing the mice, choose a location at least a mile away from your office. This reduces the chances of the furry escapees finding their way back — they are quite resourceful, after all!

So, there you have it! By using humane traps for your office mouse infestations, you’re contributing to a kinder, more caring approach to pest control.


You can effectively keep mice out of your office by implementing various strategies that focus on cleanliness, organization, and prevention. It’s essential to tidy up regularly and ensure that your office is free from food remnants, which are a major attractant for mice. Vacuuming frequently, emptying trash bins, and storing food in secure containers will significantly reduce their chances of finding sustenance in your office.

Sealing off entry points is another critical step to take. Mice can squeeze through tiny spaces, so inspect your office for potential gaps or cracks and seal them with appropriate materials, such as steel wool or caulk. This closes the door on mice seeking shelter within your office walls.

Organizing your office and minimizing clutter is a must! Create a more challenging environment for mice to navigate and find shelter, thus decreasing their chances of making themselves comfortable. Remember to keep storage areas tidy and avoid piling up boxes or equipment where these rodents can potentially hide.

Bear in mind that sometimes, professional help might be required to address a mouse problem in your office effectively. Hiring exterminators or contacting pest control services is an option worth considering if you’re unable to manage the situation on your own.

By following these guidelines, your office will become a less appealing habitat for mice. Maintaining a clean, organized, and well-sealed workplace contributes to a healthier and more productive environment for everyone.
