Best termite killer spray


An infestation left untreated can lead to severe termite damage to your home. There are many ways to treat termite infestations, and termite killers are faster and offer practical solutions to deal with termites.

What chemical kills termites?

Effective termiticides are available in stores and online, like liquid treatment, bait stations, foams, pest control solutions, and many more. A DIY termite treatment is acceptable for small infestations. However, an infestation in wood can quickly become too large and severe and is best dealt with by professional pest control companies.

In this article, we have reviewed six of the best termite killer sprays and best termite treatments. We have also reviewed the best professional pest control companies specializing in termite treatments and other wood-infesting insects.

Let’s get started on the best termite killers!

We think it is essential to know about the significant termiticides and insecticides so that you can decide which product to use.

Termiticides and insecticides

Permethrin occurs naturally from the chrysanthemum flower. It causes paralysis and death to insects.

Bifenthrin is a pyrethroid extract that occurs naturally. It will affect an insect’s nerve cells leading to death.

Fipronil is a powder that kills insects by binding to the insects’ nerve endings, shutting down the nervous system.

Imidacloprid is an insecticide that kills the nerves and will shock the insect leading to death. It is found in plants like tobacco.

Hexaflumuron is an insect growth regulator. Hexaflumuron interferes with chitin synthesis, meaning termites cannot form new exoskeletons. It is often used in bait stations.

Deltamethrin paralyzes the nervous system of insects such as termites and bed bugs.

Cyfluthrin affects the central nervous system causing paralysis and death to insects.

Taurus SC is a liquid termite killer and highly concentrated. It is applied into a trench around the perimeter of your property to form a barrier to kill termites. The worker termites walk through the protective barrier and take the poison to the other termites in the termite colony, eradicating termites, including the egg-producing queen.

For application, mix the concentrated solution according to the manufacturers’ directions. You will need to dig a six-inch trench around the perimeter of your home and pour the mix into it every ten feet.

Spectracide terminate has two functions, pop-up indicators that detect termites and stakes that kill foraging termites. The product is easy to install and can be installed within minutes.

Each set has fifteen stakes, locator shields, instructions, and a tool to dig.

Place the stakes in the ground three feet from your home and not more than ten feet apart. Check regularly the pop-up indicator to see if termite activity has been indicated. It is a good idea to place the stakes in moisture-rich soil rather than areas that are dryer, as termites prefer moisture.

What is the most effective termite control treatment?

DIY termite control can be a good short-term idea, and if you have termites outside in the soil, for example; however, a pest control company’s most effective termite treatment to eliminate termites inside should be carried out. They can offer the best termite control treatment because they have access to the best equipment and products to which you and I do not have access.

Homeowners with a severe infestation of termites need to ensure all termites or wood-destroying insects are killed indoors and outdoors. Killing termites is not easy, as termites are very good at hiding. A professional pest control company will identify the wood-eating pests in your home and have the knowledge to produce a termite treatment plan to get rid of the termites or other types of infestation.

What are the common signs indicating a termite infestation?

A Subterranean termite must stay moist to survive; it will do this by living under the soil and building mud tubes to travel to wooden structures. The mud tubes are made from wood and earth and are pencil-width. You may notice mud tubes on your home’s walls and foundations, in the basement, or on wooden structures around the house and yard.

Termite droppings are an indication of a termite infestation. The droppings are brown/black pellets found on the surface of wooden structures, floorboards, and windowsills. Termite excrement is also known as frass.

Flying termites are an indication of mature termite colonies nearby. Winged termites resemble ants like flying Carpenter ants. Termites and Carpenter ants both swarm to reproduce and build new colonies. After the nuptial flight, they discard their wings. If you notice piles of wings, it could indicate a termite infestation or Carpenter ants.

Hollow-sounding wood, when tapped, can be an indication of termites. Drywood termites and Subterranean termites eat inside the wood, leaving it sounding hollow.

Termite activity can leave the wood looking blistered and peeling.

A musty smell in a property can indicate a termite infestation.

How can I prevent termites both indoors and outside?

Remove humid, moist conditions in the home using ventilation and a dehumidifier. Termites love moisture. Removing it will repel termites.

Preventing termites outside

  • Repair any leaking pipes, faucets, showers, and baths to deter termites.

  • Use wood both indoors and outside that has been treated against termites.

  • Keep firewood stored away from the property.

  • Remove fallen trees, leaves, and tree stumps from the yard.

  • Clogged-up gutters full of leaves and pine needles provide a moist environment for termites. Clear them regularly to avoid a termite problem.

  • Do not use mulch near the foundations. It contains wood chips and moisture that will attract termites.

  • Make regular checks of the foundations for cracks and crevices that will provide entry points for termites and other pests, such as wood-infesting beetles and Carpenter ants.

  • Do not use sprinklers or water systems near the foundations. Avoid planting shrubs and trees near the foundations.

  • Check the trees in the yard; if they are overhanging onto the roof, have them cut back.
