Checking over my babies last night, in the saucers under the pots noticed that one was teeming with lively little white prawny/insecty/buggy things in the residual water, about 1-2mm long.

Any ideas what they are?
Are these gnat larvae?
What damage can they do?
How can I get rid?

Don't have pics as I wiped up the residual and bugs in one fell swoop pronto like.
