I don't think any part of your command is doing what you want it to do. This seems like an XY Problem. Can you please redo your question to ask what your goal is and I'm sure someone can help you find the correct solution.

xargs has an option to not run if no input is given:
-r, --no-run-if-empty
If the standard input does not contain any nonblanks, do not run
the command. Normally, the command is run once even if there is
no input. This option is a GNU extension.
So use xargs -r du -ch instead.

Use find with -exec:
month="Oct-2018";
find . -mindepth 1 -maxdepth 1 -newermt "01-$month -1 sec" -and -not -newermt "01-$month +1 month -1 sec" -exec du -ch ;
Though, somehow I believe, you want du -sh instead of du -ch.

Use find with -exec:
month="Oct-2018";
find . -mindepth 1 -maxdepth 1 -newermt "01-$month -1 sec" -and -not -newermt "01-$month +1 month -1 sec" -exec du -ch ;
Though, somehow I believe, you want du -sh instead of du -ch.
