I believe the bait stations being discussed are for subterranean termites, and not dry or damp wood termites. Big difference in costs to treat/check on.
Subterraneans (think Formosan) are nasty, and can cause catastrophic damage to a property in a very short number of months. Damp wood termites are easy to avoid by keeping damp wood away from your house. The dry wood termites in south Florida swarm twice a year, spring and autumn. There will be THOUSANDS of them flying around any light, porch, street, whatever.
Down here, most people get their house tented about every 10 years. The annual payments about cover what it would cost you to self insure, so basically it's a wash.
If you really commit to being on top of things, go ahead and self insure, but my house is worth way too much to me, and I've got a lot o my plate, so I'll pay up front and have the experts do the inspections. Oh, I DID have to get the bait stations, because my neighborhood is now infested with Formosans and another Asian termite, along with our run of the mill drywoods.
Do the research on your area, and make informed decisions rather than listening to folks who live a long way from you and have different situations.
