Mix equal parts water and white vinegar in a spray bottle. Spray the solution on the feeder's hanger to create a barrier ants won't cross.
Another option is to apply a line of cinnamon, cayenne pepper, or citrus oil around the hanger. These scents deter ants effectively.
Ensure the hummingbird feeder is clean and free of spills to avoid attracting ants. Regularly clean the feeder with warm, soapy water.
Consider using an ant moat - a device filled with water that creates a barrier ants can't pass. Hang it above the feeder to protect it.
Monitor the feeder regularly for any signs of ant activity. Reapply the repellent or refresh the barrier as needed to keep ants away.
By following these simple steps, you can enjoy watching hummingbirds without the nuisance of ants invading their feeders. Keep your feathered friends happy!
