Believe it or not, you can attract more birds to your backyard with water than food. Some homeowners have used water to attract as many as 65 species of birds to their backyards.
Even though birds have been known to travel up to two miles to bathe and drink, many birds simply do not visit backyards that lack water.
As such, if you do not have a water feature in your backyard, consider adding one. Something as simple as a birdbath will make a big difference. Simply make sure you purchase a birdbath that has a gently sloping bottom that has a depth of no more than 1.5″ – 2″
Is there any way to eliminate/prevent mosquito larvae in birdbaths that does not harm the birds?
Aside from changing the water in a bird bath regularly, the only thing I have hear of is something called Mosquito Dunks. They are made by Summit. I have never tried them but they are purported to kill the mosquito larvae for up to 30 days.
I have two birdbaths in my yard that or regularly filled by my auto lawn sprinklers. It’s been working for years they get filled 3 times a day and the filling rinses out everything out.
