Rosemary
The oils of rosemary are praised as highly effective in the fight against insects. You can make a natural repellent using a quart of dried rosemary combined with a quart of water and leave it to steep for half an hour.
Then, strain it into a container with a quart of cool water. Keep this repellent in the fridge and spray it on the exposed body parts before you go outside.
You can also grow it in pots or herb gardens and hang some sprigs near sitting areas.
