Exterminator can’t get rid of carpenter an

We’ve had two carpenter ant exterminator visits in 30 days. The ants are inside a recent window installation, coming out of two upper corners inside the frame, outside the window. Ant shavings are below in the corners.

There are no trails outside.

They’re spraying exterior surfaces of the outer wall and the frame.

I think it’s time to get a different exterminator. Or just spray them every few days with Raid.

Any ideas?
