@abhege I like your suggestion of using some rubber mulch to confuse termites. A good idea for many people.
I have only had one negative experience with rubber mulch which happened at a friends condo complex.
Sitting poolside with friends - suddenly, black smoke was coming from the side of the laundry room building. Fire!
There had been an accumulation of lint in the dryer vent; it sparked a fire which caused the rubber mulch to ignite.
Oh, black smoke was awful and the smell of burning rubber even worse.
