I have a set of three wooden steps resting on concrete outside a

I am afraid to try to remove any of the boards to gain access. I can
stick
a tube into the interior through a crack

At night, I tried pouring a small amount (all I happened to have) of
ammonia through the tube into the interior yo see if the fumes would kill
them or drive them out. It didn't happen.

Any suggestions will be appreciated. Thanks.

I almost hate to suggest the following, for I am sure I will be
blasted. It may also not be appropriate for your location.

If you can pour something into the hole, a small amount of gasoline
will get rid of the hornets. I do not think it kills them so much as
the smell drives them out. In my case I had a hole in the back yard and
used a funnel and a couple ounces of gas.

Sounds like a really, really bad idea. Not knowing structure or
air-flow, it allows for collection of vapor and possible fire. There
are good products, intended for the job and safe to use.
