Cleaning Your Birdhouse

Cleaning and maintaining your houses will not only reduce parasite problems and increase occupancy and bird health but will also keep your houses useful longer!

Do you need to clean bird houses?

Upkeep of your bird house is a very important step in attracting birds, and to helping maintain bird health. Old nests can contain bacteria and mites. If you don’t clean out your bird house before each nesting season, there’s a chance that disease could spread to the birds who visit or inhabit the house afterwards. Additionally, the presence of an old nest may discourage new birds from choosing to nest in your house. Cleaning and maintaining your houses will not only reduce parasite problems and increase occupancy and bird health but will also keep your houses useful longer!

When should you clean out your bird house?

We recommend that you clean your birdhouses out a minimum of once a year. Cleaning prior to nesting season is a priority but nesting boxes can be cleaned out after every brood has fledged.

How to safely clean your bird house

Here are a few helpful tips to get you started:

  • Open the clean-out door of your bird house and clean out any old nesting material or debris. We recommend wearing a pair of garden gloves or rubber dish-washing gloves when handling old nest material as it can contain bacteria and mites.

    • Check for signs of mold or mildew. If your house shows the beginnings of mold or mildew, you can clean it with a diluted bleach solution (9 parts water to 1 part bleach) or an unscented dish soap and warm water solution to keep the mold from spreading or permanently staining your house. To prevent the spread of disease and help keep young birds healthy, we recommend taking the time to follow this step even if mold or mildew are not present. A quick scrub can help prevent mold and mildew before it becomes visible as well as help eradicate any bacteria or parasites that may cause harm to the birds. Rinse well, open the door, and thoroughly air dry.

    • Inspect your house for damage. If your house has a hanging cable, how does it look? Give your bamboo or cedar house a once-over. A small crack doesn't necessarily mean your house isn't functional but be sure to fill any large cracks with wood sealant to prevent any precipitation from getting into the house during inclement spring and summer weather. Check all the screws and be sure to tighten any that may have worked loose throughout the season. Remember, birds will still use a house that isn't perfect, but you do want to ensure the house is safe.
