You'll have to look up online on what to do (the instructions are fairly vast and rigorous) but, basically, you're going to have to wash everything at a high degree of heat and put your suitcases in the garage or somewhere similar.
I experienced this in Malta, years ago, and it means that I can never, ever go anywhere without this fear.
Are you in the UK?
Sorry this has happened. My DC was 9 years old, at the time, and it was traumatising for me. I'd never even seen a bedbug and the hotel employees told me it was "normal" in high heat countries and to use PifPaf insect killer on the mattress which is what I caught them doing the next day! Apparently, that has killed some people!
So, don't panic and just return home and manage everything.
If it helps, we never got bed bugs at the house and we've never had the problem since.
I'm going away this weekend so TBC!!!!
You'll be fine but I know it sucks!
