8 plants you must have in your home to get rid of spiders and other pests

With tall stems and little purple flowers, the Agastache cana looks a bit like a lavender plant from afar. And like lavender, the smell of this plant is something that mosquitos can't stand.
5. Basil

This kitchen herb is not only great in dishes such as pizza and salad, but its smells and oils also help repel bugs. Plus, by keeping it in the house, you always have fresh basil to toss in your dishes.
6. Rosemary

If you like cooking with rosemary, this is also an awesome plant to keep around the house. Not only will you always have fresh sprigs to toss in meals and cocktails, but you'll also keep bugs at bay.
7. Lemon balm

Lemon balm's citrus smell keeps bugs away. Like the mint plant, however, it should be kept in a pot so it doesn't spread. Bonus: Lemon balm makes a tasty tea.
8. Marigolds
