When you have a subterranean termite infestation, chances are you will not be able to tell right away. These pests can hide out for years and will build their colonies underground or in your walls where they will not be disturbed. During this time, wood will be chewed up and could possibly tear down the structure of your home. The damages could leave you with extremely hefty bills and a load of stress. If an infestation is visible, you may notice swarms of these winged termites coming out during the warmer months, especially during rainfall. These winged termites are also called reproductives and look a lot like flying ants. The difference between flying ants and reproductives are that winged termites are smaller in size and have straight antennas. When reproductives are finished mating, they lose their wings that look like fish scales. You will begin to see piles of these wings on your windowsills or around wooden structures.
