FORT LAUDERDALE — A species of invasive super termites is taking their voracious appetite from dead wood and timber to South Florida’s live trees, hollowing out decades-old canopies and making them vulnerable to high winds. The change in strategy by the newly arrived Formosan and Asian subterranean termites is alarming to experts who say they are seeing signs that normally wind-resistant trees such as oaks are being compromised and put at greater risk of being toppled during tropical storms and hurricanes. …Normally termites make their homes in dead or harvested wood, such as timber used in houses and other construction. But the more voracious species, often called super termites, are finding new sources of food in some of South Florida’s largest and oldest living trees from Palm Beach County to the Keys. …Experts recommend inspecting trees annually — preferably by a certified arborist — to detect these troublesome termites early.
