If you started noticing tiny holes in the wooden parts of your house or homestead, or a “hollow sound” which appears when you knock against the wall… then it’s time to be alarmed! It is 99% likely that your house was attacked by termites. How serious is this? It’s more serious than you expect. You have to get rid of termites!
One of the main dangers of termites is that they are a very secretive enemy. You don’t have to observe any traces of their life. They might penetrate into your house from the foundation, very quickly, and empty all of the internal wooden floors of the house.
This guide will be useful when you have encountered the problem and want to protect your house from these disgusting insects. You’ll learn the most effective ways of termite treatment and what products are recommended by entomologists and professionals. What is the best termite killer on the market? Let’s start!

What Do Termites Look Like?
They are tiny insects with white bodies, which somewhat resemble ants. Many people think that all of termites have wings, but it’s not true: according to the book “Urban Entomology” written by Walter Ebeling, who is a professor of entomology, “Colonies of termites comprising winged and wingless reproductive forms and numerous wingless sterile workers, nymphs, and soldiers”. They follow a strict hierarchy typical of such insects. Once you see them in real life or at least via some online pictures, you will hardly mistake any other insects for termites.
What types are dangerous?
There are three ecological groups of termites – subterranean (inhabit both the soil and the trees), drywood and dampwood termites (prefer wooden constructions). But the most widespread groups of pest termites are the first and the second. The subterranean termites also dwell in the barns, garden houses and dunghills. They do much more harm to your property. It’s because the subterranean termite colonies are much bigger than drywood ones that is confirmed by entomologists from the Clemson University.

Termite Damage: Signs of Termites
Termites feed on cellulose. As we know, wood contains most of cellulose, and so do other derivatives of this material, such as paper, cardboard etc. When speaking about wildlife, you can hardly call them pests as they only feed on dead wood. However, since the houses are built from processed wood, they become a wonderful treat for these insects. The rot which they leave at the crime scene proves that termites are more interested in cellulose rather than the actual wood.

Michael Waldvogel, entomologist from NC State University found that termites can cause serious damage in 3-8 years of their activity. They can continue to feed on your wooden house year-round if they have a good protection from colder temperatures. Thankfully, you have some years to find out and destroy them.
Take some immediate measures or consult a specialist if you find at least one of the following:
- Tiny round holes and tunnels – Termites gnaw holes and tunnels, which is both their means of eating and their way of travelling. If you have found any cracks or other damage, try to work it up a bit wider and check whether it is regular damage or a trace left by termites.
- Rot – Pieces of rot near the holes described above is another sure sign of termites’ presence.
- Mud tubes – They are clever and may stay invisible for a long time. They also can build mud tubes from soil and parts of wood and travel inside these narros tubes. Michael Waldvogel from NC State University claims that it may be a very important sign of their activity: “Termite tubes on ceilings may indicate a “secondary” infestation”. It means that the colony actually lives in the building and the infestation is too dangerous to treat the house by yourself.
- Waste – Termites are good at hiding their presence, but terrible at hiding their feces. With that, you can track them.
- Wood attacked by termites has runways or passages that are coated with an earth-like material glued to the wood and may be rotten in appearance. Upon probing such wood with a screwdriver or similar tool, many of the hidden worker termites may spill out, says Steve Jacobs from The Pennsylvania State University.
Helpful Tip if You Are Going To Buy an Old Wooden House: It’s very important to check walls and floor in all rooms and outbildings. Don’t forget about wooden furniture! Do not be lazy: inspect every inch and pay attention to the suspicious areas and parts of wood – if the material is too soft and sounds “hollow” when you tap it, it may be a sign of termite infestation.

How to Get Rid of Termites: What Do the Entomologists Say?
If you happen to discover termites at home, most likely an entire colony has settled. People often confuse flying termites with ants as they breed at more or less the same time. When breeding season comes, males and females with wings leave their home colony. These pests are distinct from ants by their straight antennae, wide waist and two pairs of wings of the same size (ants’ rear wings are shorter than front ones).
Where can you most frequently encounter termites? Young individuals are attracted by light; they are often seen near windows and doors. If you notice them somewhere near a woodpile or somewhere else in your backyard, you don’t have to worry about this. However, if winged insects crawl out of the building’s foundation, it is highly likely that a termite mite is located in the house. Sometimes, they enter the house through the pipes under the foundation that allow them to penetrate rooms freely. These trails are as thick as a pencil and can be opened. In this case, you will see white insects swirling around. The trails might be empty as well, meaning that the insects have gnawed other paths.
The scariest thing is that you may not notice these woodworms at home for years as they live deep down and barely show on the surface. Read Top-7 Best Termite Control Products Reviews.
Can you get rid of termites on your own? The scientists from the University of Kentucky note that it is highly unlikely that you will be able to get rid of these pests on your own unless the population is small and they have invaded small areas, such as a sandbox or small wooden buildings distant from the house.
Ridding a home of termites requires special skills. Knowledge of building construction is needed to identify the critical areas where they are likely to enter. Many of these potential points of entry are hidden and difficult to access. Termite control also utilizes specialized equipment such as masonry drills, pumps, large-capacity tanks, and soil treatment rods.
Termite treatment. A typical treatment may involve hundreds of gallons of a liquid pesticide, known as a termiticide, injected into the ground alongside the foundation, beneath concrete slabs, and within foundation walls, – according to state Kentuckian scientists.
What do professionals use to kill termites? Liquid insecticides and baits will help you remove termites from your home. Soil-applied liquid termiticides have been around for decades. They create a long-lasting chemical barrier. Newer materials, such as Premise® BioAdvanced (imidacloprid), Termidor® (fipronil), and Phantom® (chlorfenapyr), are non-repellent and termites tunneling into the treatment zone are killed.
Barrier Applications | Insecticedes
Barrier applications of insecticides may be made around structural perimeters by professional applicators through trenching, drilling or rodding. Examples include pyrethroids, as well as newer non-repellent insecticides such as fipronil, chlorantraniliprole, and imidacloprid. The experts from the National Center for Biotechnology Information note the “strong colony-level effects of soil treatments with imidacloprid”. They treated 12 pest colonies with this insecticide and 75% of the colonies were removed completely within 90 days.
1. BioAdvanced 700350A Termite Killer Home Perimeter Treatment Ready-to-Spread Granules | Best Insecticede Granules
Buyer granules containing slow-acting imidacloprid are also highly rated by the customers. They are affordable and their use is simpler than that of liquid insecticide. You no longer need to dig any trenches! Place the granules around any wooden structures (i.e. buildings, fences etc) and pour them on the soil, mulched lots and lawns. Water activates granules, so water the treated territory and check out the killing effect on contact. Nine pounds of granules are enough for treating up to 200 linear feet of territory. The manufacturer promises that a single use will be sufficient.
Granules are not repelling, killing only, as the users confirm. According to the users, the pests may disappear within a week. If you don’t want to bother with digging trenches and dissolving a concentrate, these granules are your best option.

Injections of insecticidal liquids
The University of California entomologists claim that injections of insecticidal liquids, dusts, or foams may be made directly to drywood termite galleries or sometimes to shelter tubes of subterranean termites. Desiccants, oils, pyrethroids, neonicotinoids, fipronil, and many other active ingredients may also be used.
2. Taurus SC 20oz | Best Powerful Professional Liquid Insecticide
This is a powerful professional insecticide. This concentrated termiticide’s active ingredient is relatively slow-acting 9% fipronil. Once the insects come in contact with this substance, they swallow it and contaminate their nest-mates causing the entire colony to perish. All you need to do is to dissolve Taurus in water according to the manual and fill a moat around your house’s foundation. Once the product reaches the soil, it will create a long-lasting barrier protecting your place from insect pests.
Taurus SC is for outdoor use only! The exceptional reasons for indoor use are:
- Point elimination of parasites
- Removing a colony settled in the wall voids.
The product promises to solve any termite problem for less than 90 days. Apart from termites, target pests are ants, centipedes, cockroaches, crickets, earwigs, silverfish, spiders and other insects. The product has an incredibly high rating and it seems like this time the product’s premium price is actually justified. Read over 400 customer reviews to know more about its efficiency.

Termite Bait Systems for Outdoor
Baits are installed in the ground in the backyard in special plastic stations. Foragers taste the bait and share it with other insects. After that, everyone who has tried this bait dies. In some cases, baits may be combined with liquid insecticides. There are two types of baits: consumer bait products and professional ones.
Let’s now compare two slow-acting products that kill the entire population. We are talking about baits. The first one is for homeowners and the second one is professional Advance bait.
3. Spectracide Terminate Termite Detection & Killing Stakes2 (HG-96115) | w/ insect growth regulator
SPECTRACIDE TERMINATE™ with hexaflumuron, a slow-acting insect growth regulator (IGR) is available on the retail market for amateur treatment. A single pack contains several inch-long hollow plastic tubes containing sulfluramid-treated cardboard. This bait is to be installed outside and checked regularly. This method is far cheaper than professional products, but bait use is not recommended to be the only measure taken. Moreover, success depends on correct use of the product.
Bait stations contain hexaflumuron (a slow-acting insect growth regulator (IGR), are registered by the EPA. They are plunged into the ground and attract foraging termites before killing them. This device has two directions of action: detection and killing. Setting it up is a piece of cake: Dig a small hole, put it in the soil, and then wait. Once the device detects any termites, a red pillar will pop up and signal that there’s some danger.
The stakes are for outdoor use exclusively. Placing 15 stakes will let you protect up to 2,500-3,000 square feet. A single trap will serve up to 12 months before its replacement is required.
The manufacturer warns that Spectracide is not recommended for use as the only sort of pest protection. Professional products will be required against active invasions.

4. Advance Termite Bait Stations (CASE of 10 Stations) | Professional IGR
Advance Termite Bait System is distinguished among professional treatments. This latest innovation has been designed especially for getting rid of Subterranean Termites. The active ingredient in the Advance system is diflubenzuron, a slow acting insect growth regulator. The price is considerably higher than that of the products for homeowners.
This is the most recent bait product on the bait market. The active ingredient in the Advance system is diflubenzuron, a slow acting insect growth regulator.

Cartridges contain a lot of bait, enough to feed a whole colony. However, the reduction in the population will be noticeable only after a few weeks when the bait reaches the queen and sterilizes her. Without any doubt, it is worth waiting for. It is costly enough but much cheaper than hiring an exterminator.
The more bait stations installed, the better the chances of locating termites. Installing more stations increases the odds of encountering multiple colonies, or weakly associated “satellite nests” of the same colony, any of which could be of potential risk to the structure. That is why baits are sold in packages containing several units.
Cons of termite baits: Virginia State University scientists warn that because the in-ground bait stations are placed outside the structure, they do not directly affect termites that are already foraging inside.
5. BASF 805571 Termidor Foam Termiticide/Insecticide | A Foam for Removing Colonies in the Wall Voids
Termidor foam is aimed at removing pests in the walls. It contains the same active ingredients, relatively slow-acting poison fipronil. The foam is packed in a pressurized cylinder and can be successfully used as a complement to a classic insecticide. Spray it in the wall voids and other inaccessible places where a pest colony has settled. The foam is very dense so the pests won’t be able to overcome its barrier and survive, they will die of fipronil action within a few days.
Although this spray is quite expensive, users unanimously admit that it is effective and is far cheaper than consulting exterminators.

6. TERRO T1901SR Carpenter Ant & Termite Killer
This killer spray’s active ingredients are powerful pyrethroids: tetramethrin and deltamethrin. Its thin and long nozzle allows spraying this foam type of liquid deep down the wall cracks, corners, inaccessible spots, holes in wooden structures where insects have started their activity as well as straight into the nest. The spray quickly kills termites on contact. It also promises to create a protective barrier against any insects acting for up to four weeks. It can be used both indoors and outdoors.
The users claim that this spray is quite effective and is cost-saving as you won’t have to hire an exterminator. Many people have a stock of this spray in case of a pest attack. Terro is better-suited for quick protection of certain objects, so opt for slow-acting products for long-term eradication of a large colony.

7. Zap-A-Roach Boric Acid Roach and Ant Killer | Dust
Last but not least, let us present you with boric acid, a true and tested treatment against many pest insects. This simple and available product is widely used in all its forms: as a dust or bait ingredient.
This is a slow-acting stomach poison that the insects will spread around the colony. Once an insect tastes boric acid, it will slowly die of depletion. Boric acid is an external pesticide, it abrades the exoskeleton of the insect and causes death. As an internal pesticide, boric acid damages their digestive tract and kills. Termites spread the poison to other members of the colony that’s why it will kill the entire colony and a queene.

Stephen Tvedten, Pest Control Expert
Stephen Tvedten is an acclaimed expert in integrated pest management. He is also the author of a manual “The Best Pest Control 2” that focuses on natural and non-toxic methods of pest management. Stephen patented the use of compounds based on enzymes to control insects and arachnids naturally.
“One cup of Borax in a gallon of hot water, spray that and let it dry and do that three times. And you will never have termites, you will never have any mold or any mildew. It kills everything, Borax is wonderful! In addition, it makes the wood so that it does not burn. When I was working on a bait station, I took simple rolled-up cardboard, put a saran wrap around it or whatever. It should be open on the bottom and sealed on the top. You take this thing and fix it with just a little bit of Boric acid or just clean salt and any of the good antibiotics. Then you dig a hole and put it in the ground. You breathe into this thing to bring in the carbon dioxide and you stick it in the ground so that the top is level with the ground. So you will draw the termites out”.

What Is Better: Liquids Or Baits?
A limitation of all termite baits is that they are relatively slow acting compared to the effects of liquids. Several months may pass before termites find the baits underground and distribute them to their nest-mates. Consequently, the elimination process can take several months or longer to complete, and a degree of feeding and damage may occur before the bait takes effect.
Homeowners with a severe termite infestation, or those involved in a real estate transaction may not want to wait this long — preferring instead that a liquid be applied alone or in combination with baits, as the University of Kentucky entomologists comment.

How to Get Rid of Termites Naturally
If the invasion is small-scale, begin with the most humane method. As the University of Washington experts note, small pieces of wood containing live termites can be soaked in soapy water to kill the insects. Larger pieces can be taken to a landfill or natural area where the decomposing abilities of the termites are helpful.
Nitrogen and electric current. If you find parasites in dry wood, remove them with liquid nitrogen. Drill small holes in infested wood to inject nitrogen there. Another physical measure that could be taken is electricity. A special Electrogun ™ sends a low-current, high-voltage electric charge on any insects located inside dry wood. Microwave radiation is also used for this purpose.
Cardboard traps. A DIY cardboard trap has limited effect. Wet the two cardboards placed one on top of the other. Once they are full with insects, destroy cardboard with any means available. You can burn it, for instance. It’s important that you understand that this method won’t deal with new individuals appearing. Insecticide manufacturers also sell sticky cardboard traps. One such trap can be found in our list below.
Sun or freeze. These measures are rather complicated and will only be suitable for furniture and other smaller objects. You can take out the infected wood so that it “warms up” in the sun. But scientists from the University of California Agriculture and Natural Resources warn that “The treatment process involves heating all wood in the structure to a minimum of 120°F and holding this temperature for at least 33 minutes”. Can you provide these conditions? It’s difficult. Freezing is even more complicated. Put your furniture in a huge freezer, if you have one. Insects will die within 1-2 days.
Don’t worry if you weren’t able to solve your problem with the means at hand, because less than 4% of such attempts succeed. I recommend that you combine those measures with the ones below, and as a result, their combined efficiency will produce an exponential growth.
Natural Termite Killers
Dusts & powders. Drying the insects with the help of special dusts, like diatomaceous earth and silica aerogel is another control method. They cut the insects’ chitinous cover and penetrate it, causing any liquids to leave their bodies. The dust is safe for humans if not inhaled. In order to avoid any irritation of mucous membranes, wear a protective mask and safety goggles. The scientists’ opinions regarding the effectiveness of diatomaceous earth are contradictory. Some consider it effective, while others don’t. The reason for that is in one of its properties: diatomaceous earth loses its effectiveness if there is the slightest moisture. That is why it can only be used indoors on dry wood.
Natural enemies. You don’t have to eliminate the insects on your own. You can damage their trails lying from their colony to feeding spots, allowing the termites’ natural enemies, such as ants, to enter there.
Nematodes are yet other natural killers of termites. The idea here is to attack our enemy with its own weapon. Nematodes are garden insect parasites. In order for them to function, they have to enter the host’s body and consequently destroy it. A termite lives 48 hours after being infected. The downside is that the nematodes die if they do not infect the host soon after being planted. These worms can be bought at your closest gardening department store or ordered on-line. Scanmask 10 Million Live Beneficial Nematodes.
Traps. Universal cardboard traps won’t treat your house from new termite invasions but can instead serve as local protection for individual objects. They also partly help you monitor the presence of pests.
It’s interesting to know that these traps are sticky enough to trap not only insects, but also mice, lizards and even snakes. This is a cut-rate pest control option that will surely be handy.

7 Termite Control TIPS
If you haven’t yet come across any termites in your backyard or have already successfully defeated them, then undoubtedly you have to work on further prevention. Here is some advice from the respected organization, the EPA:
- After construction, keep the soil around the foundation dry through proper grading and drainage (including maintenance of gutters and downspouts).
- Reduce openings that offer the termites access to the structure (filling cracks in cement foundations as well as around where utilities pass through the wall with cement, grout, or caulk).
- Fix leaks immediately.
- Keep vents free from blockage, including plants.
- Ensure that trees and shrubs are not planted too close to the structure and do not allow them to grow against exposed wood surfaces.
- Do not pile or store firewood or wood debris next to the house.
- Inspect periodically to help ensure that termite colonies do not become established.
Rust-Oleum Coppercoat Wood Preservative is one of the best preventive products. This product has been registered with the EPA and is completely safe for humans. It’s most effective to use this repellent when constructing, but don’t worry if you have missed that moment. Take a brush and apply this liquid to all the wooden structures: rub it in abundantly and leave it to dry. Note that it is recommended to use this product outside, so you bear full responsibility if you apply it indoors.
