Termites cause billions of dollars in damage each year in the U.S to homes and businesses. They feast on the cellulose material in wooden structures, paper products, and dead trees, causing homeowners headaches across the nation. The moment you suspect an infestation, it is time to call one of the best pest control companies like Orkin or Terminix. They can spot the telltale signs by thoroughly inspecting your property. The good news is that these pest management providers typically offer this service for free.
Eliminating termites from a property is typically not for DIY homeowners. However, it is good to know what you’re up against when confronting this challenge head-on. In this informative guide to effective termite control, you’ll learn:
House Method’s pick for best same-day service: Orkin pest control
Subterranean termites live underground and require constant contact with the soil. Therefore, the first line of defense against these menacing pests is a chemical barrier.
This method involves digging a four-inch-wide trench around the home’s foundation and filling it with a diluted mixture of termiticide, such as Termidor SC with fipronil. Other suitable active ingredients include:
Products containing these substances labeled for termites will work on most species. However, it is vital to read all label directions before applying them.
It is often hard to reach into wall voids, cracks, and crevices with liquid termiticide. Products containing a foaming agent solve this problem. They can reach these tight areas where termites live and eradicate colonies at their source.
Termite bait stations containing a low dose of slow-acting, non-repellent insecticides are effective when installed around the perimeter of your home. They include a cellulose attractant that will infect the rest of the colony and eventually cause it to die off when eaten by worker termites.
Utilizing termite bait stations is an effective method for long-term control and prevention. However, they should never be used as a stand-alone treatment for active infestations.
Beneficial nematodes are microscopic parasites that burrow into the host insect to deposit lethal bacteria. Although gardeners often swear by their efficacy to kill grub worms and other pests, they should never be used to treat termite infestations.
Unlike their subterranean cousins, drywood termites do not require contact with moist soil to survive. For that reason, they can reach much higher into a structure, infesting as far up as the roofline.
Fumigation, in severe cases, is often the only way to eradicate a drywood termite colony from a home. This process requires draping the entire house with a tent-like structure. Then, the termite specialist releases a fumigant, such as sulfuryl fluoride, for up to several hours, eventually killing the colony.
The latest advances in thermal technology allow technicians to by-pass the dangerous process of fumigation and utilize a more environmentally sound approach. This method involves raising the temperature of selected sections of the structure over 120 degrees Fahrenheit for at least 33 minutes.
Drywood termites build longitudinal galleries and should not be confused with dampwood termites, which build circular galleries. In either case, you can spot-treat these areas using a wettable powder insecticide spray containing cyfluthrin.
Inject pyrethrin dust directly into the openings using a bulb duster for longer-lasting residual control. However, it will be necessary to eventually replace the damaged wood areas since using putty to fill the holes is not a viable solution.
Standard DIY solutions, such as orange oil and neem, smell nice and can be effective against some species of garden insects. However, they should never be used as a stand-alone treatment option for termites.
Diatomaceous earth (DE) is a natural insecticide produced from crushed diatoms mined from dry lake beds. It has the consistency of baby powder, and you apply it with a special bellows duster.
For long-term residual control of termites, you first have to drill 1/8-inch holes in the drywall every six feet. Next, slowly release the DE into the wall void. Last, be sure to patch all the holes when finished.
Use boric acid in the same way as diatomaceous earth. It is also effective when injected directly into termite galleries or as a crack and crevice treatment application.
DIY pest control enthusiasts often point to cardboard traps as effective against termites. The idea is to sandwich several pieces of cardboard together, creating a cellulose trap where worker termites cannot escape.
While this can be a fun science experiment for children, homemade cardboard traps should never be used to control termite infestations.
Scientists have already discovered 3,000 species of termites worldwide, and they are finding new ones every day. The ones you will run into in the U.S. are listed below.
You can find the eastern subterranean termite from Northern Maine to the Florida Keys along the eastern seaboard. It extends westward to the Ohio Valley and south to the Mississippi Delta.
This species relies heavily on moisture. It also requires its workers to build mud tubes used for traveling for colonies underground to find suitable food sources.
The primary diet of the eastern subterranean termite is wood from any structure. However, they will also devour cardboard, wallpaper, and dead tree stumps.
The western subterranean termite lives in areas along the Pacific Coast and can extend as far east as the Permian Basin in Texas. Although it is slightly smaller than its eastern cousin, it can do nearly as much damage to a home. Also, since it is adapted to live in drier regions, it requires less water than most subterranean species.
The Formosan termite is a subterranean, invasive species that scientists believe originated in the Burmese region near Southern China. It migrated to the Polynesian Islands via passenger boats and was introduced into the U.S., probably around the early 1900s.
Formosan termites are larger and more aggressive than their native counterparts. Colonies can number in the millions and can sometimes be impossible to eradicate once established.
The dampwood termite thrives along the pacific coast, from British Columbia, Canada, to Baja, California, to Mexico. You can also find them along the Gulf Coast Region, from Galveston, Texas, and into the tropical areas of Florida.
Dampwood termites infest moist, rotting wood above ground. In addition, it creates circular galleries used for laying eggs, feeding, and storing waste products.
Since this species lives in small, localized colonies, scientists caution against treating it with termiticides. Instead, it is best to replace damaged wood as needed.
You can find the drywood termite living in the southwestern regions of the U.S. and Mexico. It does not require constant contact with moist soil like its subterranean cousin. For that reason, it can infest all parts of a structure in a shorter period.
A licensed professional should determine the species of termite you have on your property. Only then can you determine the proper course of action to eliminate infestations.
To determine if you have a termite problem, you first need to complete a thorough inspection of the entire home. Start at the ground level in the basement or crawlspace. Next, check the outside area around the foundation and work your way up to the attic, eaves, and roof.
Along the way, look for signs of infestation. Here are some examples of the techniques used by professional termite inspectors:
It’s always more cost-effective to keep termites away than to treat them once an infestation is present in your home. For that reason, we list the six most effective prevention measures here.
The first step in hiring a licensed professional to treat your termite problem is to schedule an inspection. Like Terminix, most of the top exterminators in the country will do it for free if it is not tied to a real estate transaction.
It will probably surprise you to see how long it takes to complete a termite inspection. This is because most states put a fair amount of liability on the company performing it. If the inspector misses anything and your house gets damaged due to an infestation, the business could be found guilty in court.
With so much at stake, a reputable termite control provider will seriously take every aspect of the process. From the inspection to the treatment, your termite specialist will calculate every step carefully to ensure nothing is left to chance.
Nearly 90 years ago, Terminix revolutionized the pest control industry by securing the first patent for a termiticide. Since then, it has become the world’s largest provider of termite treatments, protecting thousands of homes each year from wood-destroying pests.
Technicians receive over 160 hours of initial training. But it doesn’t stop there. Terminix managers ensure that all staff members receive the continuing education necessary to keep up with changing technologies.
Some of the newest termite treatment methods the company uses are infrared heat and microwaves to lessen the impact of chemical pesticides on the environment. It also employs bait stations for added protection to deter colonies from returning.

You can argue that Orkin is the first pest control company in the U.S. Started by a rat poison salesman over 100 years ago, it has become one of the most recognizable names in the pest control industry.>
Orkin didn’t start out performing termite removal services right away. But with some reluctance, it served its first barrier treatment in 1981. After that, the company became a legend in the termite control space and has been thrilling homeowners ever since.
Orkin was also the first full-service pest control provider to implement an integrated pest management approach (IPM). This strategy employs several non-chemical and chemical methods combined to reduce the need for pesticide spraying.

The first telltale sign is structural damage. Termites burrow through sound wood to create vast galleries that appear as hollowed-out tunnels.
Another way to quickly tell if you have termites is by the presence of mud tubes. Look for them near plumbing areas and near foundation walls in crawlspaces.
Non-repellent active ingredients such as fipronil provide the best residual control of termites. In addition, insect growth regulators containing imidacloprid work well long-term.
Conversely, it is best to avoid products containing bifenthrin or permethrin. These chemicals are mostly repellent and may break down quickly under certain conditions.
The fastest way to eliminate termites is to follow these six steps :
Even if you follow all these steps, your DIY methods might not be enough. For that reason, it is always preferable to consult an experienced professional at the first sign of termites.
Here are some ball-park national averages to consider. However, keep in mind that prices vary greatly based on various factors, including the size of your home and the species.
Spot treatments: $300 – $500
Bait stations only: $500 – $1,000
Standard barrier treatments: $1,500 and up
