- Claim: Baking soda in toothpaste kills roaches.
- Reality: While baking soda + sugar can kill roaches (they eat it, it reacts with stomach acid), toothpaste doesn’t contain enough baking soda—and often includes ingredients roaches avoid (like fluoride). Worse, the moisture and residue might attract them to investigate.
- ✅ What works: Boric acid (used correctly), gel baits, and rigorous sanitation.
🐜 3. Ants
- Claim: Toothpaste blocks ant trails.
- Reality: A thick line of toothpaste might temporarily disrupt pheromone trails—but ants will simply go around it. And if the toothpaste contains sweeteners (like sorbitol or xylitol), it could lure them in.
- ✅ What works: Vinegar-water spray (1:1) to erase trails, seal cracks, and eliminate food crumbs.
⚠️ Why Relying on Toothpaste Is Risky
- False sense of security: You delay using proven methods while infestations grow.
- Waste of product: Toothpaste isn’t cheap—and it’s better used for its intended purpose!
- Potential attraction: Sugars, glycerin, and moisture in toothpaste can draw pests closer.

❤️ The Bottom Line
Toothpaste is great for your teeth—not your pest problem. While a dab might cause a brief pause, it won’t stop an infestation. Instead, focus on exclusion, cleanliness, and targeted, science-backed solutions.
“True pest control isn’t about tricks—it’s about removing the invitation.”
Save your toothpaste for brushing—and your sanity for bigger battles. 🌿✨
