Applicant has bed bugs

[Nick Janovich]

Had applicants today that are moving due to bed bugs in their home. 

I'm in the hospitality industry for my "real job" so I'm well aware of bed bugs.

What I'm not aware of is if I can decline the application based on their belongings being infested with bed bugs?

Also, they are smokers. This property is smoke-free and advertised that way. They claim they only smoke outside. I don't buy it. Legally, can I decline based on smoking? It isn't a protected class so I'm assuming yes. This property is in OH if it makes a difference.
