Ants can enter through cracks, gaps, and openings. Inspect the area around the feeder for these entry points.
Use silicone caulk to seal small cracks and crevices. For larger gaps, consider using expanding foam insulation.
Trim back vegetation and branches that touch the feeder. Ants can use these as bridges to access the feeder.
Place ant moats or traps on the feeder poles. These devices create barriers that prevent ants from reaching the feeder.
Regularly clean the area around the feeder to remove any spilled nectar or food crumbs that may attract ants.
By identifying and sealing entry points, you can effectively keep ants away from your hummingbird feeders and ensure a pest-free feeding environment.
