Get Rid of Cockroaches and Ants with Toothpaste: A Simple Home Remedy
If roaches and ants keep showing up in your kitchen or bathroom, you don’t always need harsh chemical sprays. Ordinary toothpaste can act as a quick, low-cost home remedy to help control these pests.
Why Can Toothpaste Repel and Kill Pests?
Toothpaste contains several ingredients that make it surprisingly effective as a DIY cockroach and ant control solution:
- Fluoride and detergents: These components can be toxic to small insects and contribute to dehydration when ingested.
- Strong scent: The minty or medicinal smell can repel ants and roaches, discouraging them from entering treated areas.
- Sticky texture: Its thick, tacky consistency can slow or trap small insects, making it harder for them to move around.
Used correctly, toothpaste can function as both a natural repellent and a homemade bait for ants and cockroaches.

Method 1: DIY Toothpaste Bait for Roaches and Ants
This simple mixture works as a lure-and-kill bait, drawing pests in and then dehydrating them.
Ingredients
- 2 tablespoons toothpaste (mint-flavored varieties are especially effective)
- 1 tablespoon baking soda (helps kill insects by drying them out)
- 1 tablespoon sugar or honey (acts as an attractant)
Step-by-Step Instructions
-
Prepare the paste
Combine toothpaste, baking soda, and sugar or honey in a small bowl. Mix until you get a thick, smooth paste. -
Place the bait
Use a spoon, cotton swab, or piece of cardboard to place small dabs of the mixture in strategic locations:- Near cracks and crevices
- Under sinks and around plumbing
- Behind refrigerators, stoves, and other appliances
- Along baseboards or corners where you see insect activity
-
Let the bait do its work
Cockroaches and ants will be drawn to the sweetness, consume the mixture, and gradually dehydrate and die.
Method 2: Direct Toothpaste Barrier for Ant Trails
Toothpaste can also work as an immediate ant repellent by disrupting their scent trails.
How to Use It
- Apply a thin line of toothpaste along:
- Active ant trails
- Windowsills
- Door thresholds
- Gaps where ants are entering
The strong smell interferes with their pheromone trails and acts as a barrier, causing ants to avoid the area and helping to stop them from coming inside.
Extra Tips for Better Pest Control
To make your natural roach and ant control more effective, combine the toothpaste trick with good home hygiene and prevention:
-
Keep your kitchen clean and dry
Wipe counters, sweep floors, and avoid leaving food scraps or dirty dishes out. Fewer crumbs and spills mean fewer pests. -
Use lemon or vinegar spray as a natural repellent
A simple mix of water with lemon juice or white vinegar can help deter ants and roaches when sprayed on surfaces and entry points. -
Seal entry points
Fill cracks, gaps, and holes around windows, doors, pipes, and walls to reduce access points for insects. -
Refresh toothpaste bait regularly
Replace the toothpaste bait or traps every 2–3 days so they stay fresh, sticky, and attractive to pests.
Final Thoughts
Toothpaste is not a complete replacement for professional pest control in severe infestations, but it can be a handy, inexpensive, and more natural option for minor cockroach and ant problems. With a bit of toothpaste, some baking soda, and good housekeeping, you can significantly reduce unwanted insect visitors in your home.
