How to Identify Termites 

Three types of termites are common in the US. Here, we'll show you the difference between all three and give details about their features. Then, you'll be able to tell them apart and identify each one correctly. 

Subterranean termites

Some species of termites live underground in colonies and are called subterranean. They are the smallest of the three types, and they require constant contact with the moist soil to survive. They do this by building mud tubes between the ground and the infested structure. 

Subterranean termites are present throughout the US and are broken down into eastern and western groups. However, both eastern and western subterranean termites are similar to each other. In addition, both species are made up of three primary castes:

  • Workers are about a quarter-inch long. They have narrow, cream-colored bodies. And they are the ones that feed the colony. Because of that, the workers create all of the damage to a wooden structure. 
  • Soldiers are the protectors of the colonies. They staunchly defend the workers and their surroundings. And, their large, yellow heads and saw-like mandibles make them suitable for the task. 
  • Reproductives are larger than the workers and soldiers. Both males and females have two sets of wings. After swarming, both pairs break off, showing evidence of an infestation. 

Subterranean termites feed off of the following substances:

  • Wood
  • Paper products
  • Dead tree roots
  • Fallen tree limbs
  • Wood piles
  • Books
  • Cotton

Subterranean termites are more common in some areas of the country than in others. Structures in the higher mountainous regions of North America have less incidence of termites. Also, the chance of infestation decreases if homes are treated during the construction phase. 

Drywood termites

Drywood termites are twice the length and about four times the mass of subterranean termites. They can survive without contacting the soil. And they live deep inside the wood, so they're hard to detect. 

Drywood termites construct vast galleries to hide and lay their eggs. They also bore through the wood to build "kick-out" holes to discard their fecal material. These are small, oval-shaped pellets that are about one millimeter in length and have rounded ends. 

Dampwood termites

Dampwood termites are the largest of the three species found in the US at almost one inch in length. Their cream-colored bodies may appear darker within the reproductive castes. And unlike other species, dampwood termites do not have a worker caste; it's the nymphs that are in charge of feeding the colony. 

Swarming termites often get confused with flying ants due to their similarities in appearance. However, termites have a wider body. Also, the wings of termites are equal, whereas the wings of ants are not. 

Formosan termites

Formosan termites are not native species. They were initially introduced from the Hawaiian Islands and discovered in the 1980s. Formosan termites are larger than most species. And they eat through wood much faster. 

For that reason, Formosan termite treatments require more materials to control them. Also, it could take much longer to eliminate them from homes and other structures. 

Common Signs of Infestation

Termites are adept at hiding anywhere. Therefore, it could take a homeowner years to discover an infestation. Still, there are several telltale signs to look for when trying to discover if you have a termite problem. 

Termite damage

Wood damage is the most obvious sign of termites. It can happen almost anywhere in the home. And it can show up as:

  • Material weakness
  • Termite galleries
  • Warping
  • Holes in walls and other areas

For example, baseboards, wood flooring, windows, and doors can all exhibit signs of warping. The high moisture content of termite infestations causes the wood to deform. Termites can also weaken it by chewing through several layers, resulting in the wood becoming thinner than usual. 

Mud tubes

Some termites build mud tubes to stay in constant contact with the soil. They can go from the ground up to the structure or start from the home and hang down. Also, there are exploratory tubes that often run along pipes and appear to be unfinished. Mud tubes can form either inside or outside, usually along the home's foundation. 

Live termites

Finding live termites in a woodpile or a dead tree stump may not necessarily indicate an infestation in the home. However, it can tell you that termites are present or nearby. So, it's crucial to investigate further.

Live termites behind walls and within the structure tell another story. You may have to plan on treating the home before they spread further. Also, live termites will give clues as to how large the infestation has become. 

Droppings

Termite droppings are another sign you may have a termite problem. With most species, they appear as black or brown sawdust. Also, they may appear within extensive galleries or as piles beneath kick-out holes.

Swarmers

The presence of swarming termites in the spring could indicate an infestation. And a few may show up around your home. However, that doesn't mean you have a termite problem. It's just another sign that it's possible. 

Look for shed wings. After swarming, paired couples will shed their wings, signifying they're monogamous. If there are several pairs of discarded wings around your home, it could warrant further inspection.

How to Get Rid of Termites 

The following steps will assist you in your DIY methods. Keep in mind that it may require some special equipment and materials. And in some cases, such as with large infestations, it may be better to enlist the help of an exterminator. 

Step 1. Inspection

By starting with a thorough inspection of the entire property, you understand where the termite activity is located. It also tells you the infestation level. And then you can decide on the proper course of action to get rid of it. 

Start with the basement or crawlspace. Look for mud tubes and other signs of termite activity. Also, check for damaged blocks of wood or cardboard that termites may infest.

Next, check inside the house under sinks and wet areas where termites look for moisture content. Also, use a screwdriver to pry layers of rotten or damaged wood. Last, perform a complete inspection of outside areas, including:

  • Foundation
  • Exterior walls
  • Porches, decks, patios
  • Wood piles
  • Adjacent structures
  • Tree stumps or downed logs

Step 2. Barrier treatment

Liquid barrier treatments are the most common method for controlling termites. Termiticides such as Termidor and Taurus SC work well for long-term residual management.

First, you will have to dig a small trench around the entire home. Then, mix according to the proper dilution rate as per label directions. Next, fill the channel and let it sit according to label directions before covering. 

In some instances, you can also trench the inside crawlspace for increased protection. With concrete, you will have to drill holes to access the soil underneath it. Then, using an injection attachment on your sprayer, soak the area thoroughly to create a barrier under the concrete.

Step 3. Spot treatment

Spot treatments are not a stand-alone solution but a suitable supplement to barrier treatments. For example, if you've discovered foraging termites under a sink area, a spot treatment may work well to eliminate the workers quickly. 

This method helps to speed up the process of controlling the entire structure. Also, a spot treatment cuts off the colony until the ground-based termiticide has a chance to work. 

Step 4. Crack and crevice treatment

In some instances, you can use crack and crevice applications of dry powders for residual termite control. These include mild, earth-based insecticides such as boric acid and diatomaceous earth. However, keep in mind that these are additional treatments and should not be used for primary control.

Apply dry, insecticide materials to these areas for long-term, residual management:

  • Wall voids 
  • Behind baseboards
  • Pipe entry points
  • Behind molding and window frames

Step 5. Baiting

Termite bait stations are a good choice for supplemental, long-term control of termites. However, they should never be used as a stand-alone treatment option. 

Instead, bait stations work well as a holistic management approach combined with other strategies. In addition, you can use them to lure termites away from your home as a preventative measure. 

Place the bait stations in-ground at regular intervals to attract termites. When workers eat the attractive substrate, they take the poison back to the colonies. And over time, the termites are eliminated. 

Drywood termite treatment

There are two primary treatment options for drywood termites:

Whole-structure fumigation

If your home is heavily infested with drywood termites, this treatment method may be your only option. It involves covering the house in tarps to make a tent-like structure. 

Then, a toxic gas known as sulfuryl fluoride is introduced to kill the termites. The treatment lasts up to three days, and all occupants and pets have to vacate the structure. Only when gas levels are reduced to below five parts per million are the occupants allowed back in. 

For obvious reasons, this is not a DIY project. In most states, only licensed and qualified exterminators are allowed to perform whole-structure fumigation. 

Localized (spot) treatments

In some instances, you can perform spot treatments for drywood termites. This method only works for light infestation levels. Also, it takes a high level of accuracy to pinpoint a nested location.

It's best to use a liquid foam application. Start by drilling 1/4" holes into wall voids at four-foot intervals. 

Next, apply the foam according to label instructions. You can also treat galleries and other infested locations directly using this method. 

Dampwood termite treatment

Dampwood termite infestations are typically small and don't require chemical treatment. So, it's best to remove the damaged wood areas. 

Next, it's vital to repair any leaky plumbing that caused the wood to rot. Also, be sure to provide proper ventilation to the affected area to prevent further infestation. 

How to Prevent Termites 

There are several preventative measures you can take to ensure termites stay away from your home for good. Here are just a few examples. 

Preventative termite inspections

Now that you know what signs to look for, you can perform your own preliminary inspections regularly. Still, it's preferable to hire a licensed termite inspector. They have the education and skills to do a more complete assessment. Besides, if you decide to sell your home, you'll need one, anyway.

Sanitation measures

Termites seek readily available sources of moisture. For that reason, it's crucial to repair leaky plumbing. Also, water-damaged roofs can attract dampwood termites.

Consider moving firewood back at least 30 feet from your home. Termites tend to stay away from these areas if there are no sources of food available. In addition, it's best to move mulch, cardboard, and paper materials to designated storage areas away from exterior walls. 

Home repair

Some termite species thrive on rotting wood. That's why it's vital to repair rotted wood structures. And don't forget untreated decks and porch areas. These areas can attract termites, also. 

Pre-construction termite treatments

Before building a home, consider using some pre-construction termite prevention measures. Here are some of the most common examples:

  • Termite shielding between the foundation and support beams
  • Slab collars for plumbing and electrical entry points
  • Stainless steel foundation barriers
  • Use treated lumber in all areas of the home where available

Termite traps

Cardboard traps don't work for termites. That's because there are none on the market with the proper attractant. Also, there may be too many termites within a colony. Still, new technologies may one day render termite traps an effective solution.

Termite Control FAQs 

Can termites destroy a home?

It's unlikely that termites will eat through an entire house. However, they could weaken the structure enough to cause severe damage. And it could get so bad that a home can topple to one side or the other. 

Will termites go away on their own?

Termites will not usually disappear once they've established a colony within your home. That's why it's essential to contact a reputable pest control company right away if you suspect termites. These licensed professionals can offer an inspection and sometimes a free quote. 

What do termites hate?

Heat and sunlight are the two biggest enemies of termites. Also, not having enough food and moisture is another. So, it's best to eliminate water leaks around a structure and keep food sources away from potential infestations. 

There are some natural repellents termites hate, such as orange oil. Vinegar and borax will also deter certain species. However, these substances have not been proven effective as natural pesticides, especially for termites. 

Is it safe to live in a house with termites?

Termites typically don't attack or bite people. However, winged swarmers can become annoying. And if left untreated for several years, termites can cause widespread damage. That's when a home can become dangerous to occupy. 

How fast do termites spread?

The rate at which future infestations can occur depends on several factors, including:

  • Species
  • Region
  • Local conditions
  • Type of structure
  • Prior prevention methods

For example, Florida has the greatest concentrations of termites in the US. However, Nebraska has the fewest. Therefore, the northern parts of the US will have fewer incidents of termites than the southern regions. 

Also, if a homeowner pre-treats their house before it's built, it will slow the spread of termites. Likewise, homes that are older and in vulnerable areas are more likely to become infested.
