Staying in a hotel, don’t leave bags clothes or anything lying around in the floor furniture or bed, put all your stuff in the bath/shower.
When you arrive check the mattress and it’s seams for signs of bedbugs (look up pics on Google of what to look for).
When you get home if you suspect you’ve brought some home, don’t bring anything at all into the house including shies and every single atom you are carrying.
If you can, if you have a freezer big enough, it’s a great weapon in the fight against bedbugs. Freeze everything you can that won’t get damaged by cold. Sheets clothes bags shoes bedding just go on a freezing frenzy.
