Baby mosquitos?
Anyway, any larva living in water *Should* die as soon as they leave water.
So in my opinion, you can water your plant with it. BUT, you should fix that, since larva remaining in water will turn quickly into bugs.
The larva isn't the issue. But what they turn into, is. If you store your water on the outside, this is fine, but if that's indoor, this going to be a mess :D
(I must mention that it's not verry cool for any neighborhood, having such mosquito farm :D)
