Identify where ants or roaches are entering (gaps, cracks, windows, or under doors).
Apply a thin layer of toothpaste along these lines.
Reapply every few days or after cleaning.
2. Create Bait Traps
Mix toothpaste with a bit of sugar to attract ants.
Place small amounts on cardboard pieces near ant trails.
The pests ingest it and are deterred from returning.
3. Block Nesting Areas
For roaches, smear toothpaste inside dark corners, under sinks, or behind appliances.
The strong scent disrupts their hiding spots.
4. Outdoor Use
Apply around window sills, door frames, or balcony cracks where pests often sneak in.
Extra Tips
Use white toothpaste, not gel, for best results.
Combine with regular cleaning—pests are attracted to leftover crumbs and spills.
Repeat regularly; toothpaste works best as a repellent, not a one-time solution.
Final Thoughts
While toothpaste won’t permanently eliminate infestations, it can be a cheap, safe, and effective home remedy for keeping ants and roaches away. Combine this method with good hygiene and proper sealing of entry points for the best long-term results.
