The termites in Arizona act a bit different than the East Coast relatives, typically the Eastern Subterranean termites do damage without becoming visible. With that being said, nothing is certain and always simple, termites are termites and will often do what they want to do, not according to the book. The damage eventually becomes noticeable and then that is where it becomes a horror story.  The Western Subterranean termites will make mud tubes over the foundation or make little tubes in the drywood or make little exit type holes. The Eastern Sub’s  will make exit holes but in relation to swarming.

The Western Sub’s also make down tubes quite often, as the picture below shows. I have actually seen tubes over 5 foot long stretching almost back to the garage floor.

If you find signs, just call a Pest Management Professional and do some checking with the BBB or a referral  from a friend (Kudzu).
