How do I inject Termidor in stained, tongue and groove wood ceiling?
My house has an open beam, tongue and groove wood ceiling. There is evidence of Drywood termite activity in a few of the boards; I saw droppings on the floor in the summer and I see a few, tiny kick out holes in the boards. I have several questions: 1) which Termidor product should I inject? 2) What diameter hole do I need to drill? 3) do I plug the hole with wood putty or silicone caulk immediately after injecting Termidor?
Termidor Foam would be good to use. You would drill directly into the kickout holes you are seeing so that you can get directly in the gallery where the termites actively are. You want to drill a 3/8 to 1/2 inch hole. You can plug the hole with which putty/caulk you would like after if wanted.
