There’s science behind it: garlic’s sulfur compounds have irritant and antimicrobial properties that can repel certain pests. However, results may vary depending on:
- The type of pest
- How concentrated the garlic is
- How often you apply it
While it might not eliminate an infestation, this method is a useful supplement to consistent cleaning, sealing entry points, and professional help when needed.
In summary, using garlic on door and window frames is an eco-friendly way to deter pests. Pairing it with natural sprays and scent-based repellents can make it even more effective, ideal for those who prefer non-toxic home solutions.
