What did you do with your luggage?
Vaccuum it and spray down with alcohol.
And be careful when you empty the vacuum. The little buggers are tough critters.
All my suggestions come straight from the pest company who nuked our home. The house was so hot, even the upstairs soapstone soap dish was too hot to handle. Everything that could be damaged was removed and treated. Oil paintings had to be removed because the air temperature inside the house would have damaged the oils.
Don't think you can use some over the counter remedy to kill the things. You can't. You can knock them back, but not eradicate them.
Alcohol sprayed on them desiccates them immediately, but the eggs can be in spaces you will never think of or treat.
