Fill your basement floor drain traps.
Twice a year.
The traps below the sinks in your house get replenished every time you run the water, but in many homes the traps below the basement floor drains never get refilled.The water evaporates and sewer gases start wafting up from the drain.
Pour a half-bucket of water down the drains to refill the traps. If you add a few tablespoons of mineral oil on top of the water in the traps, it floats and won't evaporate. Therefore, the water below it can't evaporate.
