Recently I was showing a buyer of mine a San Jose house which was vacant.  Often a home is occupied and the garage, in particular, is full of stuff so it’s hard to see the walls very well.  In this case, though, we could easily view where the walls in the garage meet the floor.  And this is what we saw:

Only a qualified, licensed Pest Control Operator can diagnose termites and pests, but this looks a lot like subterranean termite tubes to me.  When you see “mud tubes” such as this, it is time to call a good termite and pest control company for diagnosis and treatment.

Why do termite & pest companies insist that the garage be largely free of personal possessions when they inspect? It is so that they don’t miss things exactly like this. 

When buying or selling a home, understand that the inspectors arent being difficult if they won’t warrantee a garage as free of pests when they cannot view the walls or floor.  Bookshelves and personal storage can obstruct the view of things like this.  If you’re selling, be ready for the inspectors – have all your items away from the walls or even better, entirely out of the garage. If they have to call a packed garage as an “unknown further inspection”, it’s likely to cause you problems later, when there’s a time pressure.  Best to know upfront, for everyone’s sake, what the score is.
