How to Detect, Identify and Get Rid of Termites | Extra Mile

Picture a large, complex society made up of entities that burrow through your yard, swarm around your doors, and lurk in your house for years, patiently eating away at your walls—causing damage that you’re not even aware of. This isn’t the plot of some awful horror movie. It’s a common ordeal faced every day by homeowners across the nation: termite infestation.

According to the United States Environmental Protection Agency (EPA), “every year termites cause billions of dollars in structural damage, and property owners spend over two billion dollars to treat them.” But as common as the problem is, it can be difficult to tell whether your home has a termite issue, and treatment options can be confusing—or even dangerous.

If you’re wondering how to spot termites on your property and what to do if you find them, here are some basic tips.

Types of Termites and Where They Live

The types of termite found in the United States are the:

  • Eastern subterranean termite (Reticulitermes flavipes): This is the most common termite species in the U.S. Subterranean termites tunnel through the earth to reach food sources above ground. They can build mud tubes along exterior walls in order to access moist wood that doesn’t make contact with the ground.
  • Drywood termite (Incisitermes snyderi): The second most common termite species typically can be found in the coastal South and the Southwest. Drywood termites live in places like walls, decks, fences, and furniture, and are also commonly discovered in attics.
  • Dampwood termite (Zootermopsis angusticollis): This termite inhabits decaying wood and is found along the West Coast, in the Southwest, and in Florida.
  • Formosan termites (Coptotermes formosanus): This type of subterranean termite is found in Hawaii and a number of Southern states. They are known for being particularly aggressive and destructive.

How to Identify Termites

In North America, there are dozens of species of termites, and they vary in size, color, and shape. Usually, termites are about one-fourth to one-half inch long, although kings and queens may be longer than one inch.

Termites are often confused with flying ants, but for you amateur entomologists, there are a few differences to look out for:

  • Ants’ front wings are longer than their back wings; termites’ front and back wings are equal in length.
  • Ants have antennae that bend at a 90-degree angle; termites have antennae that are straight or drooping.
  • Ants have a narrow waist, but termites do not.

Your state’s government or university extension program may provide additional resources to help you identify termites. For example, the University of Connecticut and the Maryland Department of Agriculture offer regionally appropriate information.

Termite Behavior

Termites live in colonies, which are split into castes that perform different functions:

  • Workers have soft, light-colored bodies. They cause most wood damage.
  • Soldiers are yellow-brown with large heads and jaws. They defend the colony.
  • Reproductives are darkest and have two pairs of wings. After they mate, they lose their wings and become the kings and queens of their new colonies.

All types of termites eat cellulose-based plant materials (i.e., trees and plants, either living or dead). They also eat paper, drywall, and other materials, and can chew their way through books, furniture, and even the foundation of a house. Different types of termites prefer different environments and diets, as the names “drywood termite” and “dampwood termite” suggest.

Signs of Termites

When they recycle dead timber in the forest, termites are beneficial to the environment. But when they come in contact with human homes, termites are destructive, causing major damage to wooden structures, metal siding, and plastics.

If you see flying termites or break open a mud tunnel to find subterranean termites within, that’s a clear cause for concern.

But termites can be present on your property for years without showing themselves or causing visible damage. Absent any obvious signs, how can you tell whether you have termites?

  • Use a screwdriver to examine exposed wood for hollow spots.
  • Knock on wood structures, listening for a hollow sound.
  • Inspect places where concrete and wood meet.
  • Pay special attention to the wood in basements and under porches.
  • Check fences and tree stumps.
  • Look out for wings. Flying termites lose their wings after they swarm in the warmer months, and these wings can signal a new colony of termites.
  • Unexplained piles of small pellets could also indicate a termite presence as they could be termite frass, or droppings.

How to Deter Termites

One of the best ways to deter termites is by planning ahead. If you’re constructing a new addition or home, cover exposed sections of wood with a sealant. And avoid direct contact between the wood of your house and the soil to curtail any future problems. Don’t apply mulch directly against your home’s foundation, but leave eight to 12 inches of space.

If your house was already standing when you moved in, you can still take precautions against future infestations. Don’t plant trees or shrubbery, or pile firewood or debris, too close to your home. Keep vents free from foliage or other blockages. Fix any leaks or cracks you discover. And even if you’re currently problem-free, check your home regularly for any changes (e.g., damaged wood or cracks in the brick or concrete) in order to catch possible issues early on.

How to Get Rid of Termites

If you do notice termites or signs of termite damage on your property, you have several treatment options. Non-chemical treatments include barriers such as steel mesh and sand, but most treatments are chemical, involving the use of pesticides.

Some pesticides are classified as “minimum risk,” meaning they’re unlikely to harm humans or the environment. But most of those used against termites—called termiticides—must be licensed by the EPA and applied by a pest management professional. A trained professional may apply liquid pesticides to soil, wood, or building materials, often in combination with termite baits.

If you decide to treat the infestation on your own, make sure to carefully read and follow the directions for any products you use to ensure your safety as well as that of your family, pets, property and the environment.

Remember that, if used incorrectly, termiticides—many of which are toxic—can contaminate your home or nearby wells.

When to Call an Exterminator

If you’re inexperienced with pesticides or uncomfortable about the idea of working with potentially hazardous chemicals, it’s a good idea to call an exterminator. A trained professional will know how to use these chemicals safely, as well as how to treat for termites most effectively.

If your termite problem is more serious than you believe you can handle yourself—especially if it has reached the point where physical damage or infestation is visible—it’s a good time to turn to a professional.

And, of course, if you suspect a termite infestation, but are unable to correctly identify termites or termite damage, it may make sense to reach out to someone sooner rather than later.

How to Choose an Exterminator

Finding a reputable pest control company can feel daunting. If you’ve found one that you’re interested in working with, first, make sure that the company is licensed by your state and properly insured. Additionally, pay attention to other customers’ experiences—either through word-of-mouth referrals from friends and neighbors or online reviews—to learn more about the company’s effectiveness and customer service satisfaction.

Whether you’re actively looking for an exterminator or not, be wary of anyone who shows up at your door offering an inspection or treatment. If you’re considering working with an exterminator who has approached you, proceed with caution and get a second opinion to compare pricing and services.

The EPA’s Citizen’s Guide to Pest Control and Pesticide Safety offers additional tips on how to choose a service provider (e.g., it’s a good sign if a company is affiliated with a professional pest control association), as well as other useful information about termite control.

Just thinking about termites, let alone prodding your walls to see whether you uncover any, can be a bit scary and, frankly, extremely unpleasant. But getting on top of this potentially serious issue is essential. Preventing termite damage, and treating it properly if it does occur, will help ensure that your home stays comfortable and safe.
