Your roof vent that vents your plumbing could become plugged with leaves, debris, or snow in the winter. Check to see if it is clear.
Check your vent(s) on your drainfield for your septic system. Be sure they are free from plants, leaves, debris or snow.
Take a look at all your sinks and drains in the house and be sure to run water through them periodically, especially if they are not used often. The water that settles in the traps can evaporate and allow odors to come through.
