Selling a house -Old termite damage- Help!

[Heajin Kim]

Hello, I am selling a house and is under the contract.

Buyer has done their inspection. They found old termite damage but no active termite activities. 

Terminix told me that they did a treatment  in 2005 before I bought this house.

I have termite contract since I bought the house  from 2008.  This year, I forgot to pay termite insurance for couple of months so they had to re -instate.

Anyway, Terminix has done their annual inspection since 2008. Last one was done 11/28/2016 and before then 1/11/2016. I was told that there is no termite activities therefore, they dont do any treatment. so there was no treatment done since I lived there.

Now, my agent is telling me I have to get termite treatment because they found old termite damage even though  there isn't active termite and other wise, loan will be denied. He said treatment will cost $1,800 to $2,500.

Is there anything i can do other than spending $2K for treatment for non-existence of termite??
