9 Best Termite Killer in 2020 Reviewed

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

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![table id=22 /] 

Top 9 9 Best Termite Killer in 2020 Reviewed

1. Spectracide Terminate Termite Killing Stakes – #1 Pick

Spectracide Terminate comes in 15 stakes that will termite-treat room area of about 1,200 square foot. 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 with the Spectracide Terminate carrying the hexaflumuron back to their nests and thus cause a secondary kill effect. However, Spectracide Terminate stakes are not totally safe for both pets and kids in your household.

Its time to take action since termites might significantly destroy your ceilings, walls, basement, a big 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. In addition, 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, its easy to use, and it offers termite control and prevention. 

Cons: Should be used with other termite control solutions.

2. Harris Termite Treatment for Killing and Controlling

Next up is the Harris Termite Treatment is great for controlling massive termite infestations. It can wash down many termites that are in many bug nests – you just need to mix the Harris powder with some sprayer.

The Disodium Octaborate Tetrahydrate solution is Non-flammable, Odorless and will kill fungi, mold, Wood Rot, and Carpenter Ants. It is safe for pets and kids. However, this powder acts a repellent for termites and hence they’ll stay in areas you’ve sprayed.

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 in your porch, patio, and garage. Its active ingredient is based on boron oxyanions (borates) that extricate oxygen from the pieces of wood and hence makes the termites (and insects with no porous skin) suffocate.

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

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

3. Nissus Bora Care Natural Termite Control – Pre-Treatment

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 the reach of kids, livestock or kids. In addition, undertake thorough clean up or vacuuming when you spray in any of these places.

Types of Termite treatments

1. Liquid Termite Treatment: This method involves the use of a liquid termiticide which is 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 also prevents them from entering your house from nearby soil. Also, check the top drain cleaners.

2. Termite Baits: This is one of the best termite treatment methods that help in eliminating the insect from your house. Liquid treatment is done in entry points after thorough monitoring of the checkpoints in your house where there is a possibility of infestation.

The termites when ingesting this liquid spreads 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 new construction of home and furniture.

4. Fumigation: If your house is infested with multiple nests of termites which 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 completely and effectively.

The process involves evacuating humans and animals from the house and covering it with a tent. Then the area is fumigated with termiticide which reaches every corner and cracks of the property and kills all the termites.

Are Best Termite Killer Chemicals Safe?

Each of the above-mentioned methods on termite treatment may involve a reasonable cost which is based on the following ground: Size of the building, Severity of the infestation, Foundation details, Soil type, and the 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 fairly solid scientific evidence that termites do not see, do not smell and do not sense the environment much beyond the boundary of their tunnel system.

The seam of gold for termites is a source of cellulose (wood or plant material) or water. This is a fairly random process. It may appear that they know where there is a source of food (i.e. your house) but they find your house by a random process.

What’s the cost of professional Termite treatment

If they knew about the presence of a house then every house would be infested every year; because suburban houses represent the most attractive source of food for termites in the surrounding environment.

While the process of foraging is generally random, termites do follow natural and manmade structures. 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 side of the building or even into the building. Combine the presence of a pipe entering a building with a water leak from the pipe and you have an effective, irresistible invitation for termites to enter the building.

Equally, a piece of timber connecting the building to the ground is also an open invitation for termites to enter the house. Not only are termites foraging for food (wood) but they are also seeking reliable sources of water to ingest. This ‘drinking’ usually means eating wet soil or under ideal circumstances wet 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. In the suburban environment, there are often artificial supplies of 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 eaten in search of food.

However, termites have been known to 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 not just the structure of the building that is in danger from termite attack but also much of the contents of the building.

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 and timber 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 wood 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 actually 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 the places to spot an infestation. You may find signs of damage caused due to termites as:

1. Discarded wings of termites in your house: Termites that are reproductive 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 structures are easily visible on wooden objects of your home 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 a hollow space in any wood. If you tap on such wood, it makes a hollow sound showing an infestation. How to get rid of termites: There are a number of 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 colony. Once an individual termite forms 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 colony. One of the characteristics of the Alate caste is their ability to shed their wings after the swarming flight.

It is often the presence of these gossamer-like wings caught in spider’s 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 heavy rain event, while the atmospheric humidity is high.

– Supplementary Reproductive Caste: The Supplementary Reproductive caste, are produced by most species of termites and are 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 castes members by supplementary caste members helps to explain how a termite colony can survive and grow for many decades.
