Lavender is famous for its beautiful purple flowers and relaxing fragrance.
Its aromatic compounds, including linalool and linalyl acetate, have been studied for their potential insect-repellent properties.
Lavender products may help discourage certain insects, although simply placing a lavender plant in a room does not guarantee protection.
Potential benefits:
- Produces a pleasant floral fragrance.

- Attracts pollinators when grown outdoors.
- Makes an attractive decorative plant.
How to grow it:
- Choose a pot with excellent drainage.
- Use a light, well-draining growing mixture.
- Place the plant somewhere sunny.
- Water when the soil begins to dry.
- Avoid excessive watering.
Where to place it: Sunny windowsills, balconies, terraces, and near outdoor seating areas.
3. Rosemary – An Aromatic Herb for Your Home
Rosemary is much more than a cooking ingredient. Its distinctive fragrance comes from naturally occurring aromatic compounds.

Growing rosemary can therefore be an attractive addition to a garden or balcony, although it should not be considered a substitute for professional pest control.
Potential benefits:
- Contains aromatic essential oils.

- Can be used to season meat, vegetables, and soups.
- Remains attractive throughout the year in suitable conditions.
How to grow it:
- Choose a sunny location.

- Prune occasionally to encourage healthy growth.
Where to place it: Kitchen windows, balconies, and sunny entrances.

Basil is a popular culinary herb with a distinctive fragrance.

Potential benefits:
- Produces aromatic leaves.
- Some basil essential-oil compounds show insect-repellent activity.

Potential benefits:
