Vinegar and Baking Soda Mixtures Touted for Cleaning but Ineffective Against Pests

A home‑cleaning blend of white vinegar, baking soda and dishwasher detergent has become popular for removing grease, odours and stains on kitchen surfaces, refrigerators, drains and trash cans. The mixture works by the detergent’s surfactants, the mild abrasive action of baking soda and the acidity of vinegar, producing an effervescent reaction that lifts grime. Users are advised to mix it in a well‑ventilated area, wear gloves and avoid inhaling the fumes.

Entomologists warn that the same ingredients are often promoted online as DIY pest‑control solutions, but they lack the potency to eradicate insects such as bed bugs or cockroaches. Experts say these substances may temporarily repel adults but do not affect eggs or colonies, and repeated low‑level exposure can foster more resistant pest populations. Professional thermal treatments and targeted insecticides remain the most reliable methods for severe infestations.
