This sounds like the typical headlines from household tips and online advice columns. Behind them are usually a few tried-and-tested, natural home remedies – above all, essential oils (especially peppermint oil) and simple household mixtures with baking soda or vinegar.
Here’s an overview of which natural methods actually work against which insects:
- The Universal Remedy: Peppermint Oil
Peppermint oil is considered one of the strongest natural insect repellents, as many pests avoid its intense scent.
Effective against: Flies, mosquitoes, and cockroaches.
Application:
Mix approximately 10 to 15 drops of pure peppermint essential oil with 200 ml of water and a squirt of dish soap (as an emulsifier).
Spray the solution on window frames, door thresholds, ventilation shafts, and in dark corners.
- Against Cockroaches: Baking Soda & Sugar
Cockroaches can often only be repelled with scents, but are difficult to eliminate completely. A common natural trap is based on baking soda.
Here’s how it works: The sugar attracts the cockroaches, the baking soda reacts in the insects’ stomachs and kills them.
Application: Mix baking soda and caster sugar in a 1:1 ratio and distribute the mixture in small bowls in damp, dark places (under the sink, behind cabinets).
- Against Mosquitoes & Flies: Cloves, Lemon & Vinegar
Mosquitoes and flies rely heavily on their sense of smell.
Clove-Lemon Trick: Halved lemons or oranges studded with dried cloves act as a natural mosquito repellent on the patio or windowsill.
Apple Cider Vinegar Trap (Flies): A small bowl of apple cider vinegar, a little water, and 2 drops of dish soap attracts fruit flies. The dish soap breaks the surface tension, causing the flies to sink.
Important note: Home remedies can control minor infestations or keep insects away. However, peppermint oil or baking soda are usually insufficient for severe cockroach infestations – thorough pest control and the elimination of food and water sources are essential.
