Does anyone have experience of termite control. Bait trays or injection onto walls and doors. Are either effective and recommended

We had big problems with termites in the door and wardrobe frames.

We used Tony Goldby. He took the architraves off and drilled and injected all the frames, about 500 per door! We have not seen a termite since, and that's 3 years 

You cannot just spray, they will be back...

You need to make sure all frames are done as the little buggers move in the walls and under the floor.
