FWIW, I'm no expert, I'd say if you keep an eye on things you'll be fine. I have hardwood mulch around the foundation and no problem with termites. Termites need food *and* water, and you won't find termites where they don't have a supply of water. If you have drainage issues, then you might be concerned. If you have access to your crawlspace, you can look for termite tubes. If you see those, knock them over and call the exterminator.

Just like cleaning the lint out of your dryer exhaust... it's one of those things you have to keep an eye on.

FYI - Most brick homes (all?) are brick exterior over conventional stud walls, so don't think that brick is much of a barrier.

Finally, I spray a barrier around my foundation with a broad-range insect killer - one designed to last a year (though I spray in spring and fall). I'm mostly trying to keep spiders & the like away from the wife, but the bottle claims to repel termites as well.

Just my $0.02 & ymmv.
