Pests are a constant headache for homeowners. Whether it's ants invading your kitchen, cockroaches darting across the bathroom floor, or mice sneaking into your pantry, these little intruders can create a lot of frustration, hygiene concerns, and unnecessary cleaning. While the go-to solution for most is chemical traps and poisons, what if there’s a simpler and cheaper alternative right under your nose? Believe it or not, toothpaste—yes, the very same tube you use to brush your teeth—can help keep pests at bay.
In this article, we’ll explore the surprising ways people use toothpaste to deter common household pests, why it might work, and how to safely apply it without endangering your family or pets.
Why Pest Control Matters at Home
Pests are more than just annoying; they can pose significant health risks. The Centers for Disease Control and Prevention (CDC) warns that rodents like mice and cockroaches can bring in harmful bacteria, allergens, and even parasites. While ants may seem harmless, they can still contaminate food and cause structural damage to your home.
Common pest-related issues include:
Food contamination from ants or cockroaches
Allergy flare-ups due to rodent dander or cockroach droppings
Unpleasant smells or stains from pest nesting sites
Noise and property damage caused by mice chewing on walls or wires
Keeping your home clean and tightly sealed is essential, but sometimes, that's not enough. This is where natural pest deterrents, like toothpaste, come into play.
Why Toothpaste?
You might be wondering how something so common as toothpaste could help with pest problems. It may sound strange, but toothpaste—especially mint varieties—contains ingredients that many pests find unappealing. While scientific studies on toothpaste as a formal pest repellent are limited, anecdotal evidence suggests it can work in the following ways:
Peppermint oil and menthol in toothpaste produce a scent that ants and mice find unpleasant.
The strong chemical aroma can mask food smells, confusing insects who rely on scent trails.
The sticky texture may act as a barrier for crawling pests.
While toothpaste isn't a permanent solution, it offers an inexpensive and quick fix to keep pests away from certain areas while you work on a more comprehensive long-term pest control strategy.
How to Use Toothpaste for Different Household Pests
1. For Ants
Ants follow scent trails to find food, so disrupting these trails with toothpaste can discourage them from returning.
How to apply:
Identify areas where ants enter, like cracks in walls, windowsills, or corners.
Apply a thin line of mint toothpaste along or near these entry points.
Reapply daily or after cleaning the area.
Extra tip: Mix toothpaste with a small amount of baking soda and place it on small paper pieces to create a natural barrier near ant trails.
2. For Cockroaches
Cockroaches are tough pests, but they tend to shy away from strong minty scents.
Try this DIY remedy:
Mix toothpaste with a bit of sugar and flour.
Place small amounts on a piece of cardboard or in shallow dishes in areas where cockroaches are likely to roam (like under appliances or in corners).
The sugar attracts them, while the minty toothpaste scent deters them.
Note: This isn’t a trap, so it won’t kill the cockroaches but can help steer them away.
3. For Mice
Mice are sensitive to strong smells, and mint or menthol scents are particularly off-putting. Toothpaste can keep them from returning to certain areas.
How to use it:
Apply a line of mint toothpaste along the edges of cupboards, baseboards, or suspected entry points.
Refresh the application every few days.
For better results, combine toothpaste with physical barriers like steel wool or sealed gaps.
Toothpaste Safety Tips for Home Use
Toothpaste is relatively safe to use around the house, but a few precautions are necessary:
Avoid overuse around areas pets might lick, as some toothpaste contains xylitol, which is harmful to dogs.
Don’t apply toothpaste directly to food surfaces or areas where you prepare meals.
Keep it out of children's reach, especially when mixing with ingredients like baking soda or sugar.
Use toothpaste as a supplement to other pest control methods, but for larger infestations, always contact a professional pest control service.
Other Natural Pest Control Options
While toothpaste is a good start, consider incorporating other natural pest control methods to help keep pests at bay:
Peppermint oil spray: Mix 10-15 drops of peppermint essential oil with water in a spray bottle and spritz it around entryways and baseboards.
Vinegar solution: A 50/50 vinegar-water mix can disrupt ant trails and clean surfaces.
Bay leaves or cloves: Place them in pantry corners to deter weevils and cockroaches.
Cucumber peels: Ants hate cucumber, so place fresh slices near their gathering spots.
When to Call a Professional
If pests keep coming back despite your best efforts, it may be time to call in the experts. Recurring infestations could be a sign of deeper issues like structural damage, moisture problems, or food access points that require professional attention.
It’s time to call a pest control specialist if you:
Spot pests frequently during daylight
Notice damage to food packages or furniture
Hear nighttime noises coming from walls or other hidden areas
Find droppings or foul smells near nesting sites
Final Thoughts
Toothpaste may not be your go-to pest control solution, but it’s a surprisingly handy tool when it comes to minor pest problems or preventive care. Its strong scent, sticky texture, and easy availability make it an affordable way to keep ants, roaches, and mice at bay.
Just remember, natural methods work best when paired with good home hygiene practices, such as sealing cracks, properly storing food, and keeping your living space tidy.
