Pond bugs...indoors !

[TANGOMAN]

Well, I've had the pond plants and Koi down in the basement for over a week now. The first couple of days the aphids were in full bloom. Fortunately they cycled and died off before they found the fruit bowl in the kitchen. That'd go over well eh...? . I have changed my ways it seems. The odd spider in the house isn't such a bad thing anymore.
I now see I have a problem with a new insect. A big problem. . They're tiny. They look like a beetle. Sorta...? They don't fly. At least not yet. (I'm prayin' it stays that way!) These things are devouring my water lillies though. I noticed "chomp" marks on the leaves when they were outside. I figured the fish were just stupid...well, they are stupid but it's not them chompin' on the leaves...

Is there an insecticide that is safe for the fish ? I'm thinkin' not but I haven't yet looked. Should I fire up the U.V. sterilizer and hope to get 'em if they're floatin' around...?
HELP ! If these things get airbourne, I'll be gettin' airbourne too...
