Here are seven key points for proper maintenance of humming bird feeder

Regular Cleaning: Clean the feeder thoroughly at least once a week, preferably every few days during hot weather or if you notice any mold or debris buildup.

Use Hot Water: Rinse the feeder with hot water before and after cleaning to help remove any remaining residue or soap. Avoid using harsh chemicals or bleach, as they can be harmful to hummingbirds.

Replace Nectar: Refill the feeder with fresh nectar every 3 to 4 days, especially in warm weather when nectar can spoil more quickly.

Avoid Red Food Coloring: While some commercial nectars contain red dye to attract hummingbirds, it's best to avoid using them as they may be harmful to the birds.

Shade Placement: Hang the feeder in a shaded location, if possible, to help prevent the nectar from spoiling too quickly in the sun.

Ant Moats: If ants are a problem, consider using an ant moat—a device filled with water that creates a barrier between the ants and the feeder. Hang the moat above the feeder so ants cannot reach the nectar.

Monitor for Pests: Keep an eye out for any signs of pests such as bees, wasps, or ants. If these insects become a problem, you may need to relocate the feeder or use additional deterrents to keep them away.
