<div dir="ltr"><strong>Fish and Tadpoles<br><br></strong> Koi may be beautiful, but are generally too large to prey on mosquito larvae. However, since Koi are known for their mellow nature, you might consider adding some smaller fish. Common goldfish, killifish, and guppies are three types of fish that are known to eat mosquito larvae and will get along well with other fish. If you have a natural pond that is not stocked with bass, bluegill, or catfish, you might want to consider adding some fathead minnows. Bass, bluegill, and catfish are all natural predators to mosquito larvae and will not need any additional help. <br>
<br> If you have a pond or any water source that does not have any fish, consider adding some gambusia affinis, better known as the mosquito fish. Mosquito fish are about an inch long and look similar to a guppy. A large female gambusia is capable of consuming over two hundred mosquito larvae in an hour. They are very aggressive fish and begin attacking the larvae when they are only a couple hours old. Unfortunately, they will also attack dragonfly larvae (which are another predator to mosquito larvae) and will be aggressive toward other fish and tadpoles. <br>
<br> Mosquito fish are very hardy and capable of adapting to different temperatures and salinity. They live naturally in the southern United States. However, some varieties of mosquito fish have been bred to survive colder temperatures, even down to -30<font><sup>o</sup>F. They are livebearers and can produce three to four broods each summer of about twenty-five to one hundred young each. You do not have to worry about them over-populating since they are also very aggressive towards each other. <br>
<br> If you have a large birdbath that is constantly filled with water, consider adding about ten fish. Larger ornamental ponds can support anywhere from 35 to 100 fish. For wastewater ponds, add about 1000 fish per acre. Minnows, guppies, and small goldfish can also be added to birdbaths and ornamental ponds, but they are not as hardy as the mosquito fish. You do not have to worry about feeding them either, since they sustain themselves on what they find in the water. <br>
<br> If you're not interested in having fish, consider tadpoles. Tadpoles not only eat mosquito larvae, but they grow up to become toads or frogs, which will eat mosquitoes. One toad can consume about a hundred mosquitoes a night. <br>
