How to kill mosquito larva in my pond but not kill my koi?
Question:
Answers:
Mosquito larvae cannot tolerate a lot of oxygen in the water, so put in some kind of feature that aerates the water. ( A fountain, a waterfall, a bubbler, or even oxygenating plants should work.) Also mosquito larvae cant tolerate moving water, they like it to be as still as possible, so you could install a feature that will move water. (Once again, a fountain or a waterfall would work.) I am kind of surprised that the Koi aren't eating the larvae. You can also buy a product called Mosquito dunks at local stores such as Walmart, Lowes, Home Depot and most garden supply stores. They kill the larvae by interrupting their digestive system and they starve to death. The dunks are not harmful to fish, plants or pets.
You can get some fish at the local pond or pet shop that will eat the larvae.
aereate it by pointing a hose up in the air and keeping the water stirred up. It provides air for the koi and mosquito larve doesn,t survive in agitated water. thats why in florida gated communities and mall water displays, you always see fountains shooting in the air and agitated water.
Mosquito Dunks are safe for your Koi. I use the flakes and just sprinkle them in every 2 weeks. Although, you would think your Koi would LOVE to eat the little buggers.
mosquito larva are too small for large koi to eat. u should add mosquito fish to ur pond. these resemble very drab looking guppies. as their name implies, they'll eat the mosquito larva and rid ur pond of the pesky critters. if u don't want to add anymore fish, then there are mosquito dunks that u simply add to the pond. these can be purchased online or at stores that sell pond items such as home improvement stores.
