More than termites, we would be concerned with wood-boring beetles. These often have larvae in the wood happily eating away. By the time you see holes, it may be too late. Check the wood. If it has small holes, it probably has some. This tends to be a problem when using reclaimed wood.
Your best option is to call us and see if there is any way we can help you with this. In some markets there may be some small fumigation chambers available where you could take the wood. Call now to see what can be done.
