What can we do about a Fishy smell in basement? Help!

Help! We are stumped. We tried flushing the drain with vinegar/water/2 tbps cooking oil several times. I tried running the self clean for my washer.

We noticed the odor coming from globe arborvitae by our front stoop, so we chopped it off. I’m not sure if that is the culprit, for the odor is still there.

My husband thinks it is from the dryer vent. I’m sure that something has died. I asked him to check the ceiling outlet located above our washer and dryer unit. I am confused.

The odor is definitely located in the basement near the wash tub (sink) that is next to the washer.

What else can we do?

    Try adding water to all your floor drains. My laundry room floor drain sometimes emits a foul odor and adding water to get it back up to level seals off the gas that gives that horrible smell.

    If it smells like 'Dead Fish' it is either a dead rodent, possum, squirrel, or very stagnant water in an old boiler, a/c tank, bucket? drain? pinpointing the place where it's the worst may help solve what it is, if it's a rodent etc, the smell will eventually decline, however there is a danger from disease fouling the air and any drains etc, if it's stagnant water it won't improve much and may get worse whilst becoming more toxic and a breeding ground for mosquitoes etc.. finding the source of the smell is important.

    Good luck,
