Help!!!We have been in our house for almost a month and for the last 2 weeks have had this terrible smell that permeates from the garage somewhere and comes through the house, it is a split level house. It smells almost like it could be something dead. You can smell it in certain places in the house, such as a downstairs bathroom, the kitchen, sometimes in our hallway, and in the master bedroom above the garage sometimes. We also have a problem with gnats flying around. What could this be and who would I have come and find what it is. Cant stand it anymore, we feel we got a bum house. Can anyone help? Thanks
