I have found that my aquaponics system has had very few pest problems. I think this is in part due to the health of the plants in my system and that I have planted several plants that attract beneficial insects in my garden. I have also taken care to provide habitats for the ultimate insect assasins in South Florida - Lizards. What do you do to mitigate pests big and small in your aquaponics systems? Raccoons, whitefly, aphids etc.
