Top 9 Best Termite Killer 2022 Reviewed

Below I’ve reviewed the best termite killer for indoor and outdoor spaces. Luckily, the products are useful for both pre-and post-construction phases.

First, termites (damp wood, dry wood subterranean) are tiny white-bodied insects that’ll bore wood and house foundation. Also, termite inspection costs might be high.

Termites will bore tiny round holes on wooden furniture or walls as they feed on wood cellulose, cardboard, and paper. So, let’s get started!

Spectracide Terminate Foam2 is described as a spray foam that will expand to get to the deepest areas where the termites are hiding in your home. 

  • The termite foam will expand, filling the wood spaces in your structures and hence bars the termites from coming back alive.

Its attachable nozzle enables one to spray both indoors and outdoors, including deep inside termite nests and holes.

However, since the Spectracide Terminate Foam2 is considered mildly poisonous, you must not spray in hospitals, food areas, or places within reach of kids, livestock, or kids.

  • Also, undertake a thorough clean-up or vacuuming when you spray in any of these places. 
  • If they knew about t house’s presence, every home would be infested every year; suburban houses represent the most attractive food source for termites in the surrounding environment.

While the process of foraging is generally random, termites do follow natural and human-made structures. 

4. Spectracide Terminate Termite Killing Stakes

Spectracide Terminate Termite Detection and Killing Stakes, 15 Count
  • Two termite products IN one: pop-up indicators detect termite activity, and the stakes kill foraging termites
  • Installs IN minutes: place stakes in the ground 2 to 3 feet away from your home and no more than 10 feet apart
  • Pop-up indicator: check the stakes for termite activity when the pop-up indicator is seen
  • Complete kit: includes 15 stakes with locator shields, instruction booklet and digging tool

Spectracide Terminate comes in 15 stakes that will termite-treat room area of about 1,200 square feet.

  • Equally, this roach termite solution (“termite baiting”) has a long residue effect – going up to 1 year, while also killing other foraging bugs

The termites will contact the Spectracide Terminate carrying the hexaflumuron back to their nests and thus cause a secondary kill effect.

However, Spectracide Terminate stakes are not safe for both pets and kids in your household.

It’s time to take action since termites might significantly destroy your ceilings, walls, basement, a significant portion of your house, and other wooden structures.

With a full instruction booklet and a digging tool, you’ll find this termite stakes solution easy to use. 

The active ingredient in these termite stakes is an insect growth regulator (IGR) – exactly Hexaflumuron (0.50%), which damages the termite’s chitin production.

The Spectracide Terminate “bait” has the “sulflurimid,” which is cellulose food that termites will eat to throw themselves to their death. Besides, the termites (remember they are foraging insects) will bring the sulflurimid back to their nests and poison the whole colony.

Pros: It has pop-up indicators and locator shields, it has pheromones for better performance, it’s easy to use, and it offers termite control and prevention

Cons: Should be used with other termite control solutions.

I recommend that you get a reliable sprayer (with termiticide plus) while taking care not to spray on flowers, houseplants, and fruits as it can be harmful. Review the following homemade fruit fly traps

This termiticide can also help protect the wood that is on your porch, patio, and garage.

Its active ingredient is based on boron oxyanions (borates) that extricate oxygen from the wood pieces and make the termites (and insects with no porous skin) suffocate.

Pros: Will protects the wood from rotting and getting molds, it is non-toxic to pets and kids, inflammable, and odorless.

Cons: May damage flowers, fruits, and other plants such as grass.

Types of Termite treatments


1. Liquid Termite Treatment: This method involves using a liquid termiticide, sprayed in and around your home where an infestation is noticed. Any termite which comes in contact with it (including the natural termite treatment) is either repelled or killed.

  • Nonrepellent liquids are also used, which does not make their presence noticeable by termites and kills them effectively in their place.

The soil surrounding your property should be treated with such termiticide for effective eradication and prevent them from entering your house from the nearby ground. Also, check the top drain cleaners.

2. Termite Baits: This is one of the best termite treatment methods that help eliminate the insect from your house.

  • Liquid treatment is done in entry points after thorough monitoring of the checkpoints in your home, where there is a possibility of infestation.

When ingesting this liquid, the termites spread it to other mates in the nest and get controlled much effectively. Check the top bombs for fleas.

3. Borate Termite Treatment: Also known as wood treatment, it is basically done to eradicate the dry wood termites.

  • A termiticide containing borate is directly applied to the wood surface infested with termites, which dies immediately.
  • The treatment is odorless and does not cause harm to humans. It also acts as a preventive measure for termite infestation when applied during the new home and furniture construction.

4. Fumigation: If your house is infested with multiple nests of termites that are hard to eradicate with a single treatment, fumigation of the entire structure is often recommended by experts.

  • It is the best answer to how to treat termites entirely and effectively.
  • The process involves evacuating humans and animals from the house and covering it with a tent.

Theresa is then fumigated with termiticide, which reaches every corner and cracks on the property, and kills all the termites.

Are Best Termite Killer Chemicals Safe?

Each of the methods mentioned above on termite treatment may involve a reasonable cost based on the following ground: Size of the building, Severity of the infestation, Foundation details, Soil type, and Climate.

The foraging behavior of termites (the process of finding food) is a common source of misunderstanding by consumers and the source of folklore dispensed by unethical termite treatment salesmen.

  • There is relatively concrete scientific evidence that termites do not see, do not smell, and do not sense the environment much beyond their tunnel system’s boundary.

The seam of gold for termites is cellulose (wood or plant material) or water. This is a somewhat random process. They may know where there is food (i.e., your house), but they find your home by a random process.

What’s the cost of professional Termite treatment 

For example, it is not uncommon for termites to follow pipes and conduits that run through the surrounding environment into buildings.

  • These pipes and conduits can unwittingly, but effectively, lead the termites to the building’s side or even into the building.
  • Combine the presence of a line entering a building with a water leak from the pipe, and you have a compelling, irresistible invitation for termites to join the building.
  • Equally, a piece of timber connecting the building to the ground is also an open invitation for termites to enter the house.

It is not only termites foraging for food (wood), but they seek reliable water sources to ingest. This ‘drinking’ usually means eating wet soil or, under ideal circumstances damp wood.

Foraging for food and, therefore, the tunneling process of termites is relentless. The process continues day and night, winter, and summer.

Foraging and feeding do slow under dry and or cold conditions. There is often artificial water (leaking pipes, air-conditioner condensation, for termites to exploit even during prolonged periods of drought.

  • Soil temperature usually remains within a range suitable for optimum termite activity during most of the year, although air temperature varies widely.
  • It would only be during the depths of winter in the southern latitudes and the height of summer in the northern latitudes that soil temperature may become limiting to termite activity.
  • In the process of foraging for food, termites will eat through materials with no nutritional value. The soil is the major component of the material consumed in search of food.

However, termites have been known to the tunnel (randomly eat) through seemly inedible materials such as lead sheathing on cables, rubber tires on tractors, and hard plastics.

In the building situation, termites can tunnel through plasterboard lining, carpet underlay, plastic sheeting, and the list go on.

Feeding and Digestion

Termites feed on cellulose (plant material). The main component of wood is cellulose. It is cellulose that the termites need for food. It is not just the building structure that is in danger from termite attack but also much of the building’s contents.

  • It is not just the structural and building timbers on which termites feed but anything of plant material origin (e.g., paper, cardboard, ply-board, furniture, cotton cloth, wood musical instruments, etc.).
  • Termites eat plant material (commonly wood) as a source of cellulose. Cellulose forms the structure of plant tissues. For example, cellulose comprises about 50% of timber and 90% of cotton fibers. Cellulose is a polymer (long-chain) of thousands of glucose (sugar) molecules.

Termites cannot digest cellulose. Termites must rely on micro-organisms (bacteria and protozoa) in their intestines (gut) to digest the cellulose and release the sugars. In this respect, the digestion system of termites is similar to that of the cow.

Signs of termites infestation

You’ll need to keep an eye on both places to spot an infestation. You may find signs of damage caused due to termites as:

1. Discarded wings of termites in your house: Reproductive Termites are called and fly to other places to find new homes. If you see a group of such insects flying around your home or trace some discarded wings, there is probably an infestation around you.

2. Tube-like structures made of mud: Such systems are easily visible on your home’s wooden objects like wooden flooring and furniture and even on walls. It is nothing but a part of their nest, which is damaging your property.

3. Wood, which sounds hollow: Drywood termites feed on cellulose and create an open space in any wood. If you tap on such timber, it makes a hollow sound showing an infestation. How to get rid of termites: There are several options to choose from for treating termites. The treatment depends upon the type of termite present in your home and the degree of infestation.

Colony and Organization

– Mature termite colonies: Mature termite colonies may number in the hundreds of thousands or even millions of individuals.

Each colony is composed of individuals belonging to defined castes. Each caste has specific jobs or responsibilities to perform within the territory. Once an individual termites form into a worker or soldier, the process cannot be reversed.

– The Reproductive Caste: These are the Queen and King of the colony. The Queen termite, like the Queen Bee, is the only egg-laying individual.

– The Alate Caste: Alates are fully formed adult insects with eyes, wings, and reproductive organs. The purpose of alates is to form new colonies and sustain the species.

Alates must begin a colony in the ground. Alates cannot fly into your house and start a nest. Successful alates become the Queen and King of a new territory. One of the Alate caste characteristics s their ability to shed their wings after the swarming flight.

It is often the presence of these gossamer-like wings caught in spider webs, littering the floor, or floating on the top of the pool, that alert homeowners to an occurrence of a termite swarm in the previous night.

Swarming usually occurs in the late afternoon or early evening after a storm or massive rain event, while the atmospheric humidity is high.

Supplementary Reproductive Caste: The Supplementary Reproductive caste is produced by most termites species and is potential alates. Supplementary are thought to be Queens and Kings in waiting. 


For example, if the current Queen was to die, and there was no replacement, the colony would soon die.

  • A supplementary Queen takes the place of the dead Queen, and the colony survives.

This replacement of reproductive caste members by supplementary caste members explains how a termite colony can survive and grow for decades.
