I have built my first deck on my new house out of hardwood, and also rigged up some irrigation hose with holes, along the perimeter where it meets the waffle slab. I also traced smaller diameter pipe around the base of each stump. There is a layer of plastic sheet under each pipe with course sand on top.
What I need to know is what kind of liquid can i pump around this system to stop termites? Whatever liquid it is will be soaked up by the course sand and hopefully deter termites from eating my new deck.
A friend of mine once said that Telstra paint capsicum liquid on their cables, but where do you get this stuff from.
Any other ideas
