Dry Wood Termites
I have had dry wood termites swarming in my house this summer. What is the minimum amount of time the termites have been living in my house, given that they are swarming?

It is hard to say "what is the minimum amount of time the termites have been living in your (my) house" since the drywood termite swarmers are attracted to light and can enter homes from the outside.
I have attached a link to a Texas A&M Publication on drywood termites.
If that link is bad please go to this link for information.
I hope this answers some of your questions.
