Termites, by their nature, are hard to find. Thriving in hard-to-reach, inaccessable areas, they eat your home from the inside out. Although there may be only a few indications of termite activity, take a closer look at these warning signs:

Watch for the “swarm” of winged termites during the day or evening and often
   after rainfall from February to March, in most areas of the country.
Check in or around windows and doorframes for termite evidence (wings, etc.)
Look for “mud tunnels” in or around the foundation, under windows and on walls.
Watch for pin-sized holes in the wall and woodwork where termites exited during
   the swarm.
Tap baseboards and floors to see if they sound hollow — a possible sign of
   termite infestation.
Examine window sills and walls for dead termites or termite wings.
