Overview
- TN.com.ar and La Gaceta detail a chopped onion and lemon juice preparation placed under sinks, behind refrigerators, near drains, and in rarely used cupboards to deter cockroaches.
- Both outlets stress the mix is a repellent rather than an insecticide and advise renewing it every two to three days while maintaining strict hygiene and sealing entry points.
- Los Andes, citing Healthline, recommends spraying freshly diluted lemon after thorough cleaning to create an olfactory barrier where ants and cockroaches travel.
- TN.com.ar also promotes an alternative household blend of white vinegar, baking soda, and lemon to clean surfaces and discourage multiple pests.
- Los Andes reports that applying boric acid in cracks and along baseboards after lemon treatment can reinforce control and help prevent reappearance.
