If you’ve ever spotted a cockroach scurrying across your kitchen floor or lurking in a bathroom corner, you know just how unsettling these pests can be. Not only are they unpleasant to see, but they can also carry bacteria and trigger allergies. While there are countless sprays and traps on the market, many people are turning to a surprising household item for a safer, cheaper solution—toothpaste.
Yes, that same tube you use to keep your teeth sparkling clean may just be the secret weapon to eliminate cockroaches once and for all.
🪳 Why Toothpaste Works Against Cockroaches
The secret lies in common ingredients found in regular (non-gel) toothpaste, such as:
-
Fluoride – toxic to insects when ingested
-
Baking soda – reacts inside the cockroach’s stomach
-
Strong mint scent – repels and confuses pests
Cockroaches are attracted to the sweet smell of some toothpaste brands. Once they consume it—especially when combined with other household items—it becomes a deadly bait they can’t escape.
