Even termites are unwelcome. The suberin, the inherent substance of cork, is a natural insect repellent
Perhaps the most valuable asset of cork flooring is the ease of maintenance. Today, waxing is no longer needed. Sweeping and mopping will be the usual maintenance. A few years down the road when the finish starts to wear off, lightly sand the floor and reapply a new coat of urethane. Your floor will last for several decades.
