Pest control...you pay or tenant?

[Clint G.]

My tenant told me they saw a roach (1 roach) in the house the other day. He didn't seem really upset about it, but it got me thinking...should I have a pest control company come out quarterly to spray or should that be on the tenant? My feeling is it should be on the tenant, but what are your thoughts? In my area, it's around $350/year to have a company spray quarterly. 

Thanks
