Hello,
I live in a condo. About a year or more ago the construction company made holes in my ceiling of my mechanical room because they were trying to locate a nose issue (heating system) Since then I been experiencing plaster/fungus beetles. I have no idea from where. In that room I have my washer and dryer. The system is RNC (Lifebreath model) the heating is gaz. Could they be entering from the drain holes? Maybe the washing outlets in the wall? Thanks
