worm stink ?

I woke this morning to a stinky house not sure if its the worms the office where I keep them didn't smell to bad though..hmmm I put them.outside just in case and I am not feeding them for a week or two I think I have too much food and they are not keeping up ...I know some have died...I don't think a lot but enough that they can't eat 1/2lb of food a day ..I read that its better to underfeed than overfeed ..I will continue  to just put stuff in the freezer for them...
