Just thinking out loud, supposed house has no termites.

Can I use the baiting system as preventive measures? Seems counter-productive, as I may be inviting termites to come to my house!

Your is terrace of bungalow? If terrace, I'll stay away from your house.
Baiting system are 1 of the most stupid idea of 21st century to begin with.
Termites can come from air and from ground. If you use baiting system, you are asking them to come near to your house. But as recommended by seller, you need to keep on changing the bait which cost you money all the time.
Now come to flying termites, how to prevent them? You can, as long as you turn on the lights.

Don't bait if you don't have problem.
