Is it true that if you keep a small pond in your garden with toads, frogs,that they will eat all the mosquitos?
When they usually start doing this and how they do this?

I have noticed since having the pond in the garden with the toads sitting on the lilly pads, I have not had much of a mosquito problem (SURPRISINGLY).

Get a couple of mosquito fish…
and you will have no mosquito problem at all. Yes, the toads eat many of them. Surprisingly enough, goldfish do not. They are essentially vegetarians.
You can also use Mosquito Dunks, a product that eliminates mosquitoes and does not harm your pond.
But toads and frogs eat mosquitoes as a main part of their food supply. But a few mosquitoes always escape to buzz you. Best to keep them at bay with another means.

Mosquito fish

Remember awhile ago we talked about mosquito fish

I got this letter from a fish farm owner who adds to my education and, I hope, yours about these critters.

Hi Jan,

I was reading your comments about mosquito fish, (Gambusia).

I raise millions of these fish for mosquito control at my fish farm in Florida. Also we raise Koi carp, tropical fish and all sorts of aquatic and bog plants.

When in ponds with other fish they present little or no problem. Like a lot of fish they are territorial, when in small areas like fish tanks they will defend their territory by ganging up on other species of fish.

Bottom line is they are a native fish which have been around for a long time. I hear comments like they eat fish eggs, frog eggs and tadpoles. This is true but tell me one fish that does not do the same and most of them have a lot larger mouths.

The biggest enemy we have at the farm are the walking catfish. These fish are decimating many of our smaller tropical fish.

I enjoyed reading your article.

Best regards,

Colin D. Calway.

Tiny pond

I call this the tiniest pond I have ever done. It is simply a casserole dish balanced ecologically so the water will not be stagnant.

Now I can hear all of you saying, "What about mosquitoes? What about West Nile Virus?"

We use mosquito fish to keep those biters gone.

The fish have a large appetite, and one female can devour several hundred mosquito larvae per day. They reproduce rapidly and are unlike other fish, they bear live young. Each female can produce three to four broods in her lifetime, and each brood can vary from 40 to 100 fry.

Birth usually occurs during the warm spring and summer months. When the young are born, they are active and immediately swim for the nearest cover. Though they are only about 3/8-inch long, they will soon feed.

Sounds wonderful, doesn't it? Well, not quite.

Mosquito fish have negative ecological impacts anywhere they are introduced. They compete with native species of minnow for available forage or harass those competitors until they die. They have been especially devastating in the American Southwest interacting with a wide range of threatened or endangered fish species.

Many states are using the fish for mosquito control. As always, I wonder if the cure will be worse than the disease.
