Small White Mosquito Larva Looking Things

[6lkl6l]

there in my 10g, all my guppies had ich so i moved the fish out cleaned the tank, filled it back up.
all i have in there is my little pleco, and i can see these little white things moveing around like mosquitos.
im in florida but its too cold outside for them to be out and even if it wasnt i dont know how they would get in the tank anyway.

any ideas on what they are?
