"However, there is a plug in the end that sticks through the vent. Its purpose is to prevent bugs and dirt/dust from blowing back into the refrigerator through the condensation drain hose. "
Hmmm, I never had a plug on mine. Is this plug removable? Pourous? Maybe I'll tywrap a piece of screen over mine.
Never had a bug in the fridge either that I know of.
