Pest problems are an unwelcome visitor in any home. Whether it’s a trail of ants in the kitchen, a cockroach darting across the bathroom floor, or mice sneaking into your pantry, these tiny intruders can cause frustration, health concerns, and extra cleaning. Many people immediately turn to chemical poisons and traps—but what if a simple household item could help? Surprisingly, some homeowners swear by toothpaste as an effective and affordable alternative for keeping pests at bay.
In this article, we’ll explore the creative ways people use toothpaste to discourage common household pests, why it might work, and how to apply it safely without putting your family or pets at risk.
Why Pest Control Matters at Home
Rodents and insects aren’t just nuisances—they can also pose real health risks. According to the Centers for Disease Control and Prevention (CDC), pests like mice and cockroaches can carry bacteria, allergens, and parasites into your living space. Ants, while less dangerous, can still contaminate food and damage walls or wooden structures.
Common issues caused by household pests include:
-
Food contamination from ants or roaches
-
Allergy triggers due to cockroach droppings or rodent dander
-
Unpleasant odors or stains from nesting
-
Noise or property damage caused by mice chewing through walls or wires
Keeping your home clean and sealed is key—but it’s not always enough. That’s where natural pest deterrents, like toothpaste, may come in handy.
Why Toothpaste? The Surprising Ingredients That May Deter Pests
It may sound odd, but toothpaste—especially mint-flavored varieties—contains several ingredients that pests dislike. While there’s limited scientific research on toothpaste as a formal pest repellent, anecdotal evidence suggests it may help in the following ways:
-
Peppermint oil or menthol in toothpaste is a strong scent that ants and mice find unpleasant.
-
Strong chemical aroma can mask food smells, disrupting scent trails insects follow.
-
Sticky texture may act as a barrier to crawling pests.
Think of it not as a permanent solution, but as a quick, affordable way to discourage pests from certain areas while you work on a long-term prevention plan.
How to Use Toothpaste for Different Household Pests
1. For Ants
Ants use scent trails to find their way back to food sources. Disrupting these trails with toothpaste can discourage them from returning.
How to apply:
-
Identify entry points, such as windowsills, wall cracks, or corners.
-
Apply a thin line of mint toothpaste directly on or near these access points.
-
Reapply daily or after cleaning the area, as needed.
Extra tip: You can also mix toothpaste with a small amount of baking soda and apply it to small paper pieces to place near ant trails.
2. For Cockroaches
Cockroaches are tough to get rid of, but they tend to avoid strong minty smells.
Try this DIY trick:
-
Mix toothpaste with a bit of sugar and flour.
-
Place small amounts on a piece of cardboard or in a shallow dish in corners or under appliances.
-
The sugar lures them, and the toothpaste scent can disrupt their behavior.
Note: This is more of a deterrent than a trap—it won’t kill them but may steer them elsewhere.
3. For Mice
Mice have a keen sense of smell and may avoid areas that smell strongly of mint or menthol. While toothpaste won’t harm them, it may keep them from returning to certain zones.
How to use it:
-
Apply mint toothpaste along the edges of cupboards or entry holes you suspect they use.
-
Refresh every few days.
-
Combine with steel wool or sealed barriers for better results.
Toothpaste Safety Tips for Home Use
Using toothpaste around the house is relatively safe, but it’s still important to take precautions:
-
Avoid using too much, especially where pets might lick it up. While non-toxic in small amounts, some toothpaste contains xylitol, which is harmful to dogs.
-
Do not apply directly to food surfaces or anywhere you prepare meals.
-
Keep away from children’s reach, especially when mixed with other ingredients like baking soda or sugar.
-
Use as a supplement, not a complete pest control method. For infestations, always contact a licensed exterminator.
Other Natural Pest Control Options to Try
While toothpaste may help in mild cases or as a stop-gap solution, here are a few other natural approaches that many homeowners use:
-
Peppermint oil spray: Mix 10–15 drops of peppermint essential oil with water in a spray bottle. Spritz around doorways and baseboards.
-
Vinegar solution: Vinegar disrupts ant scent trails. Use a 50/50 vinegar-water mix for cleaning.
-
Bay leaves or cloves: Place in pantry corners to deter weevils or roaches.
-
Cucumber peels: Ants dislike cucumber; place fresh slices where ants gather.
When to Call a Professional
If pests keep returning despite your best efforts, it may be time to call in an expert. Recurring infestations can signal deeper issues such as structural entry points, dampness, or food access that requires professional sealing or fumigation.
You don’t need to wait until it gets serious. Contact a pest control specialist if you:
-
See pests frequently during daylight
-
Notice damage to food packages or furniture
-
Hear noises at night or in walls
-
Find droppings or strong odors near nests
Final Thoughts
Toothpaste may not be the first thing that comes to mind for pest control, but for minor problems or preventive care, it can be a surprisingly handy tool. Its strong scent, sticky texture, and common availability make it a low-cost way to discourage ants, roaches, and even mice from settling in your space.
Just remember: natural solutions work best when combined with good habits like sealing cracks, storing food properly, and keeping your home clean.
