please help

i volunteer at this place called the hope center. well this woman that came in said she has two sons with autism and they have nobody to play with. im 15 and love playing with kids and just kids in general. but she called me today and while we were talking she mentioned they have bed bugs. if i go over there for like 30 mins- 1 hour will i catch them? i kind of don't want to do it now but i will feel bad canceling on them when i promised to go play. what should i do? and im sorry im kinda freaking out and don't know what to do.
