Bad smell in basement

Hi

For past few days , bed smell can be felt in basement.
The basement is unfinished and I have checked throughly there is no dead animal in or around.

Can’t see any water or drainage leakage anywhere.

Really puzzled, any suggestions

Thanks

Maybe the drain in the basement is letting sewer smells up,maybe trap needs to be filled with water?

This. Find the floor drain(s) and pour some water in them. The trap may have dried out.

like said, if you checked for dead animal and any water seeping / leakage it's likely the floor drain that emptied, letting sewer gas / odours in. Fill it with water, mixed with just a little bleach. If you ever are concerned about a gas leake from any gas appliance, call the gas company or the fire department, they will come and take an air sample and test it, this is a serious security concern if it is gas

bad how? sewage? gas? Mold? pour boiling water in your floor drain. If you have sinks and toilets down there, give them a flush.

Kidding aside, I find that during the hot and humid days my basement starts to smell a bit musty.

It goes away after I run AC for a few days. Not sure if it's just condensation on the foundation or something else, but it happens during the summer mostly.
