BED BUG HELP

Nancy

We had a house fire last week, and cannot live in our house again until next week, so my husband and I are staying in a town an hour away from our house with his grandma. But I work in the city of our house and have doctors appointments as well, so today I had to stay in the city tonight after work because I have an appointment super early in the morning and didnt want to drive all the way back to the city so early, so I'm staying at my cousins house, I get the house to myself and get to sleep in her king size bed which is nice, BUT, I'm laying in her bed, look over, and see something tiny crawling, so I turned the flash on on my phone, and it looked exactly like a bed bug , I killed it and then googled a picture of it and it HAD to be a bed bug. I texted my mom, who's getting me in the morning, and told her.

Does anyone know how I can avoid bringing them back to my husbands grandmas with me?? just wash my clothing?????
