3 meter centres for your termite stations is the optimum distance to ensure there are no gaps for the termites to breach the barrier in search of a food source which could be your home. If you’re serious about protecting your home, you are better off investing in a complete kit rather than being left short and having to deal with $$$ of termite damage. We can customise a kit to suit if need be, just give us a call on 1300 965 532 or email [email protected] We’re happy to help.
