Is it easy to attract termites by planting flowers in the corner?

Don't worry, it won't. Termites are scavengers. They usually nest in rotten wood, sand or walls and don't eat live plants. So a flower bed won't attract termites. If there are termites, the flower beds will not affect them. On the contrary, termites don't like that very humid environment. The flower beds that are often watered are places they don't like!
