Simply draw a line of Nectar Fortress™ natural gel across any paths ants might use to get to your hummingbird feeder to stop them in their tracks. Made entirely from food-based ingredients, it repels ants, but is safe* for use around children, birds, and pets. It is weather-resistant and long-lasting. One tube contains enough gel to protect up to 10 feeders. Nectar Fortress is also great for protecting many other outdoor areas from ants, such as patio tables, bluebird houses, beehives, and hanging plants.
