Should I proactively try to prevent termites, and if so, how?

I live in NE Kansas - partially wooded area with about 35" of rain a
year.

The house was built in 2000. Original owner has a pest company come
out and spray, set bait traps, etc. I'm inclinded to do as much as I
can myself. I'll spray a perimiter pest spray to keep down spiders,
etc. But what about termites? Is this a serious threat -- one worth
hiring the pros to prevent?

Take a look at this web site http://www.doityourselftermitecontrol.com/products.htm

A couple I know used this system last year and it seems to be working. I am
going to try it myself.
