Dealing with unwanted pests like mice scurrying in the walls, cockroaches darting across the kitchen floor, or trails of ants marching toward your pantry can be incredibly frustrating and stressful. These intruders not only disrupt your peace of mind but can also contaminate food and surfaces, making everyday life feel unhygienic and overwhelming. You’ve likely spent money on commercial poisons and traps, only to see the problem persist or return. But what if a common household item already sitting in your bathroom cabinet could offer some natural support in deterring them? Keep reading to discover an intriguing home tip that many people swear by—and why it might be worth trying before reaching for harsher options.
Why Pests Invade Our Homes in the First Place
Pests like mice, cockroaches, and ants are drawn to our homes for the same basic reasons: food, water, and shelter. Mice seek warmth and crumbs during colder months. Cockroaches thrive in moist, dark areas with easy access to scraps. Ants follow scent trails to anything sweet or greasy.
The truth is, no home is completely immune. Even the cleanest spaces can attract these visitors through tiny cracks or open doors. But that’s not all—commercial pest control products can be expensive and involve chemicals you might prefer to avoid around kids or pets.
Here’s the interesting part: Some everyday items with strong scents may help make your home less appealing to these pests.
The Role of Strong Scents in Deterring Pests
Many pests rely heavily on their sense of smell to find food and navigate. Overwhelming or unpleasant odors can disrupt this, encouraging them to look elsewhere.
Research on natural repellents has highlighted certain plant-based scents, like peppermint, as potentially helpful. Studies show that peppermint oil can interfere with insects’ and rodents’ olfactory systems, making areas less attractive to them. For instance, the menthol in peppermint is known to repel various pests by overstimulating their smell receptors.
But here’s where it gets practical: Many toothpastes, especially mint-flavored ones, contain peppermint oil or similar compounds for that fresh feeling. Anecdotal reports from homeowners suggest applying mint toothpaste around entry points might help deter mice, ants, and even cockroaches due to the lingering strong scent.
Of course, this isn’t a guaranteed solution—results vary, and it’s best used as part of a broader approach. But many find it a low-cost, non-toxic option to try first.
How Toothpaste Might Help with Specific Pests
Mice and the Mint Connection
Mice have an incredibly sensitive nose, which helps them locate food but also makes strong smells a potential deterrent. Peppermint-scented toothpaste applied along baseboards or near suspected entry points may create a barrier they avoid.
Some sources note that the intense mint aroma can mask food scents or simply overwhelm mice, prompting them to steer clear. While not scientifically proven as a standalone method, it’s a popular home remedy backed by user experiences.
Cockroaches and Scent Disruption
Cockroaches are notorious for hiding in cracks and emerging at night. The strong mint in toothpaste could help disrupt their trails when dabbed in problem areas like under sinks or behind appliances.
Again, the key seems to be the peppermint component, which studies on essential oils suggest can repel roaches by interfering with their navigation.
Ants and Trail Interference
Ants leave pheromone trails for others to follow. A line of mint toothpaste along their path might break this trail with its potent smell, causing confusion.
Home tips often recommend this for minor ant issues, especially since peppermint has shown promise in repelling ants in various observations.
But remember, this works best for prevention or light infestations—severe problems may need more.
Step-by-Step Guide: Trying the Toothpaste Tip at Home
Ready to give it a go? Here’s how to do it safely and effectively:
- Choose a mint-flavored toothpaste—peppermint or spearmint varieties work best for their stronger scent.
- Identify problem areas: Look for entry points like cracks around doors, windows, baseboards, pipes, or gaps in walls.
- Apply small dots or thin lines of toothpaste directly in these spots. Use a cotton swab for precision.
- Reapply every few days, as the scent fades over time.
- Combine with good habits: Seal food in containers, wipe counters clean, and fix leaks to remove attractants.
- Pro tip: For mice, place dots near walls or in cabinets.
- For ants: Draw lines across their trails.
- For cockroaches: Focus on dark, moist hiding spots.
This method is non-toxic for humans and pets when used this way, but always keep toothpaste out of reach of children.
Other Natural Scent-Based Options to Try
If toothpaste isn’t enough, consider these complementary ideas:
- Pure peppermint essential oil soaked on cotton balls (dilute if needed).
- Cinnamon or clove sprinkles around entry points.
- Vinegar sprays to wipe away trails.
Here’s a quick comparison:
| Method | Ease of Use | Cost | Scent Strength | Best For |
|---|---|---|---|---|
| Mint Toothpaste | Very Easy | Very Low | Medium | Quick home trial |
| Peppermint Oil | Easy | Low | High | Stronger deterrence |
| Cinnamon Powder | Easy | Low | Medium | Ants specifically |
| Commercial Traps | Moderate | Higher | None | Heavy infestations |
When to Call in Professional Help
While these home tips can be helpful for minor issues, they’re not a substitute for expert intervention if pests persist. Signs you might need pros include frequent sightings, droppings everywhere, or damage to wiring/food.
Professionals can identify root causes and use targeted, safe methods.
Frequently Asked Questions
Is mint toothpaste safe to use around pets and kids?

How long does the toothpaste deterrent last?
Typically a few days to a week, depending on ventilation and humidity. Reapply as needed for ongoing effect.

It’s more about deterrence than elimination. For full removal, combine with cleaning and sealing entry points—or consult a pest control expert.
