This year, the usual horde of fruit flies swarming our fruit bowl seemed non-existent. I realized this is probably due to the herbs we have on our kitchen windowsill. Strong-smelling herbs, oregano, rosemary and others, repel fruit flies. Even in winter months a few stray fruit flies make their winter abode in our home. To keep them out of the fruit bowl I’ve placed a piece of rosemary amidst the fruits.
