Keeping Your Bird Bath Clean & Healthy

Did you know that bird poop can carry more than 60 diseases, some of which affect humans? That’s why keeping your bird bath clean is so very important.

Here’s a small sample of what you’re up against:

  • Histoplasmosis, a potentially fatal human lung disease
  • Salmonellosis or “food poisioning,” which makes birds very sick
  • Candidiasis, or yeast infections
  • Chlamydia
  • West Nile Virus, carried by some birds and by mosquitoes, which lay eggs in still water

So let me be really clear: if you’re going to have a bird bath, you’ve got to be absolutely committed to keeping it very clean. If you’re not, you’re going to find that algae, bird poop, feathers, dead leaves, mosquito eggs and other yucky stuff builds up pretty fast.

Keeping Your Bird Bath Clean

Got a garden hose handy? Put the nozzle on the high pressure setting and hose the bird bath out every day. Keep the bird bath in a sunny place to discourage the growth of a parasite (Trichomonas gallinae) that spreads easily among birds. The sunny location will promote more algae growth, but there are easy ways to deal with that.

Once a week or so, fill the basin with a 10% bleach solution, then scrub the basin and rim with a stiff bristle brush. (This scrubbing is especially important if your bird bath is made of concrete or a similarly porous material.) Finish by rinsing thoroughly to get rid of chlorine.

If you do this every week, a light scrubbing will keep the nastiness away. It’s easy work, as this video explains.

Don’t like bleach? You can use white vinegar and water, but it doesn’t work as well to kill pathogens.

Note: Do not use sanitizers, germicides, ammonia-based cleaners, or cleaners containing phenol, pine oil or any petroleum product. (Toxic to birds.)

Products That Make the Job Easier

For Cleaning

If your bird spa has been neglected for awhile, these products are good for cleaning a bird bath without scrubbing (or with less scrubbing):

CareFree Birdbath and Statuary Cleaner — Enzyme product that removes tough water lines, odors and mineral deposits. Can be used on plastic, concrete, vinyl, stone, glass, ceramic, metal and marble bird baths. Safe for wildlife and the environment.

Brush Attachments for Your Cordless Drill

Keeping your bird bath clean is easier with power brushes for your cordless drill.
Take it easy on your muscles by “powering up” the scrubbing with a heavy duty brush that attaches to your cordless drill.






To Keep Water Clear

CareFree Birdbath Protector — Biodegradable enzyme-based solution. Breaks down organic contaminants and prevents mineral scale. Safe for birds, pets and wildlife.

Sanco Bird Bath & Fountain Maintenance — Another enzyme product, similar to Care Free.

Healthy Ponds All Purpose Water Cleaner — Naturally occurring bacteria and enzymes keep bird bath clean, clear and free of organic growth. Safe for fish, plants, birds, animals and humans

For Controlling Algae

EasyCare FounTec Algaecide and Clarifier — Kills algae and prevents further buildup. Safe for plants, birds and wildlife but NOT SAFE for fish. Consider this if you live near a stream or have an unlined pond with fish in it.


Does Copper Really Keep a Bird Bath Clean?

You may have heard that tossing a few pennies or a bit of copper into your bird bath will keep it clean, but is it true?

Yes and no. Copper does retard the growth of algae and some bacteria somewhat. But as this photo illustrates, even bird baths that are entirely made of copper still need cleaning.

Don’t use US pennies though – all US pennies are at least 95% zinc, which is highly toxic to birds. Acidic water, oxidation through exposure to air, and harsh cleaning chemicals may expose the zinc core beneath the copper.

(Canadian pennies minted between 1876 and 1996 are at least 95% copper, but mostly zinc and/or steel thereafter.)

A better option would be to use a bit of copper piping or other large-ish copper items that birds can’t swallow if they are attracted to the shiny copper.


Mosquito Control

The still water in bird baths can be a mosquito breeding ground if it is allowed to rest undisturbed, and can facilitate the spread of mosquito borne diseases such as West Nile Virus, Zika Virus, dog heart-worms, malaria and various forms of encephalitis.

Mosquito eggs can hatch in as few as four days, so be sure to change the water in your bird bath at least every three days to give mosquitoes the boot.

Products for Mosquito Control

Note: Don’t use chemical insecticides in your bird bath! They may harm pets, birds and other wildlife.

If you can’t empty and refill your birdbath twice a week, or if the mosquitoes have somehow gotten ahead of you, here are some safe, non-toxic products you can use to get rid of them.

Summit 20-Pack Mosquito Dunk — Donut-shaped tablets that release Bacillus thuringiensis israelensis, which kills mosquitoes but is not harmful to birds, fish or other wildlife. Each donut covers 100 square feet and lasts for 30 days.

 Clarke – Natular DT Mosquito Larvicide — An insecticide based on chemical compounds found in the bacterial species Saccharopolyspora spinosa. Not toxic to fish, plants or birds but causes moderate eye irritation in people and pets.

EcoSMART Organic Mosquito Control Tablets — Contains a blend of essential plant oils that kills insects by blocking specific neural pathways that only insects have. Safe for people, pets and wildlife. Propietary formula kills mosquito larvae for up to three months.

There’s a better way to keep mosquitoes out of your bird bath and attract more birds at the same time: tell mosquitoes to buzz off by adding sound and motion to your birdbath.
