Cost of pest control

[Rj Kro]

Hi all-got a landlord question. I rent a single family home-we actually lived in the house, up til 2.5 years ago. Had a nice family move in when we moved out, and they had no pest issues for 2 years. A new tenant moved in Jan 1 2018. The house was empty for a week or so. This week, the new tenant said they are having a bedbug issue-they of course moved all their furniture in, bought new furniture, and they work retail. As best I can tell, it seems probable that their furnishings/themselves are the source of the issue. The Orkin man they got a quote from told me that he thinks it is likely their furnishings. The tenant is asking me to pay for the treatment cost. I've never crossed this bridge as a landlord. Any thoughts?
