I have a set of two wooden steps resting on concrete outside a door. *The

get in and out.

I am afraid to try to remove any of the boards to gain access because they
are very aggressive.

In a previous post I was asked for pictures. *You can see them at:

Any suggestions will be appreciated. *Thanks.

Dust where they go in and out with a little sevin dust. They will take
it into the nest. It may take a week but this is abou the easiest way
to get rid of them. If you can gently blow a little under the steps
with a vacuum cleaner that good too.
