So, you're thinking about calling an exterminator to address those nagging worries you have about termites eating your house out from under you. Maybe you think you hear the sound of chewing in your walls or you just discovered a winged ant in your house and fear the worst. Termites are found in 49 of the 50 states and cause an estimated $50 billion in damage to buildings and dwellings every year. If you detect the presence of multiple winged termites inside your house, there's a good chance there's a termite nest nearby using the wood in your home as a food source. Because termites eat wood from the inside, you usually won't see surface damage. We always recommend a termite inspection to our buyers and sellers. A termite inspector may be able to tap a wood beam and detect a low or flat sound that indicates that the wood is somewhat hollower on the inside than it should be. If termites are detected your home may need to be tented or just a local treatment. Damaged wood is generally easy to replace, but remember that termites will normally come back so you may want to consider ongoing pest maintenance by a licensed pest control company.
