birdhouses should be cleaned early each spring. Cleaning helps remove bacteria and parasites, thus promoting a healthy environment for birds.
Wear gardening gloves to keep your hands clean and safe. Open your birdhouse and remove all debris and
nesting material. Use a plastic bag to
dispose of debris.
Use a small brush and weak bleach solution (one part bleach to
nine parts warm water) to clean the inside, making sure to clean all corners
and the entrance hole.
Rinse the birdhouse with clean water for several minutes to
remove all traces of the bleach solution. Leave the birdhouse outside and dry in the sun for several hours. The sun will help thoroughly dry the inside
to prevent mold and mildew, plus remove all traces of the bleach solution.
Reassemble your birdhouse, making sure all the hinges are
secure. Be sure all ventilation holes
are open and unobstructed.
