Small Prob...What should I do?

Yesterday, I noticed that a couple of leaves on just one of my plants has fly "crap" on it. I'm not too worried because I know that outdoor plants must get that shit all the time. I know its fly crap because I say the little fucker in there.
My question is should I trim those leaves off? I noticed it on 2 leaves more towards the bottom.
Could I put one of those "fly catchers" in my closet? although nothings in there now I'd rather be safe than sorry...

trimming leaves i dunno but a fly catcher wouldnt hurt

are u sure???? what kinda light you using??? if its HId id rethink the fly paper deal...imagine what those do when heated
