Why is cleaning so important? 

Birds leave behind droppings, feathers, and food scraps in their nesting and feeding areas. Over time, these can become breeding grounds for harmful pathogens. The biggest risks include: 

  • Mold: Spoiled food and damp conditions encourage mold growth, which can cause respiratory issues in birds. 
  • Parasites: Mites, fleas, or feather lice can settle in old nests. 
  • Bacteria and viruses: Particularly at feeders, droppings and saliva can lead to the spread of diseases. 

Regular cleaning reduces the risk of infections and helps maintain a healthy bird population in your garden. 

When should you clean? 

The best time to clean a birdhouse is after the breeding season, in late summer or autumn. If birds use the house for winter shelter, consider a second cleaning in early spring before the next breeding season. 

Feeders, on the other hand, should be cleaned at least once a week—even more frequently in summer, as warm and humid weather accelerates bacterial growth. 

How to clean a birdhouse 

  1. Empty the birdhouse

Remove old nests, feathers, and other debris. Wear gloves to avoid direct contact with droppings or parasites. 

  1. Brush out dry dirt

Use a stiff brush to remove dust and loose dirt. Be sure to clean all corners and edges thoroughly. 

  1. Wash with hot water and vinegar

Use a mixture of hot water and vinegar (1:1) or a mild, eco-friendly soap. Avoid chemical cleaners, as they can be harmful to birds. 

  1. Rinse with clean water

Thoroughly rinse the birdhouse to remove any residue. 

  1. Let it dry completely

Allow the house to air dry before hanging it back up. Moist conditions encourage mold growth, so make sure it's completely dry.

Tips for maintaining a hygienic bird environment 

  • Daily checks: Remove leftover or damp food every day. 
  • Set up multiple feeding stations: This reduces overcrowding and minimizes disease transmission. 
  • Clean water sources: Birdbaths should be cleaned daily. 
  • Use high-quality food: Choose fresh, high-quality bird food to avoid mold and spoilage.
