Nothing!!! If they are coming to see my house they can go home. If they are coming to see me they are welcome.
There are days, when I am sewing, that the house looks really bad, but its way more important to me, to sew. I don't mean that the place would get condemned, but if I don't get the sink cleaned that day or floor swept, oh well.
Hubby always says "we live here and if someone doesn't like it, they can go home!"
