Default Mosquito larvae in Jun's "pond"

If this is the small pond you had on that website, a few drops of veggie
oil will smother them. After a few days, put in an air stone and keep the
water agitated so new skitters won't be tempted to lay eggs. ~ jan



Excellent advice. The dunks work, and I don't think they are toxic, but who
really knows.

The oil works very well because the little mosquito larvae float just below
the water and breathe through a snorkel tube. The oil clogs up the snorkel,
and voila the little critters are gonzo. Any type of oil will work, but the
usual kitchen type oils are inexpensive. It only takes a very small amount,
as a teaspoon will cover about a (US) acre. It won't hurt the fish, but you
have to add more regularly.

As for the air stone, that may work to deter egg laying, but I'm guessing
you'd have to really roil the water to have any effect. And even then there
would be calm spots here and there. Mosquitos are very successful insects
for a reason - they can get along in nearly any environment. The oil will
probably deter them just as effectively.
