The best way to detect them is to consult with professional pest control operators and have inspections. A homeowner can help by regularly checking for signs of them by looking for mud tubes on slabs, foundations, and piers. These tubes are a sure sign of termite presence but can also represent an old infestation. Tiny holes appearing in walls or ceilings should be examined by a trained professional to determine whether they are caused by termites or other wood-destroying insects. While a few flying termites may come into a home during swarming season, the appearance of more than a few termites flying inside the home or deposition of many wings may indicate an active colony hidden within the walls of a home. Not all termites are Formosan and it takes a practiced eye to know which termite is present. Some drywood termite alates look very much like Formosan alates at first glance. The methods of control of these species are very different, so accurate identification is essential.
