Obviously it probably isn’t enough if you’re in a small room where your suitcase is next to your bed, but for clothes you could try putting them in a vacuum bag (as in one of those plastic bags that you seal up and then suck all the air out with a vacuum)
I do it anyways because it means way more space in your suitcase but that would probably contain any bugs that are in your clothes

stop taking your clothes out of your suitcase as well. leave the suitcase zipped up in your hotel bathroom or bathtub.
