Termites and duplexes

[Jason C.]

Last week my tenant tells me she sees ants in the kitchen... a lot of them. I asked her to handle the exterminator and told her I would reimburse her, she set up a pro and he treated for ants. A few days later she reaches out again saying the ants are still there and is having the pro come back to take a look.  When the pro comes he notifies her that they are not ants, but termites and that he will put her in touch with a termite pro. The townhouse is a duplex and another owner owns the other side so I am going to notify them and ask them to treat their unit as well and try to split the costs. Anyone have any experience with termites and treating them, and or dealing with another owner on splitting costs?
