Taurus SC at a Glance

Taurus SC is one of the most effective termite products on the market today. Before you begin using Taurus SC, you will need to dig out a six-inch trench around the perimeter of your home. Once you’ve done this, pour the Taurus SC mixture in every 10 feet.

Taurus SC does not repel termites. Most termites are able to detect repellents and can avoid them. With Taurus SC, termites can’t smell it, so they cross over it and bring the poison back with them into their nest. Although Taurus SC isn’t as fast as some other termite insecticides, it is much more thorough in the destruction of the entire termite nest.

Within a few short weeks, termites will rapidly begin to die, and towards the end of the 90 days, the whole colony will be exterminated.

If you’re dealing with other pests, too, Taurus SC kills roaches, ants, wasps, centipedes, and many other insects. Taurus SC is great for homes with pets because its active ingredient is the same as the ingredient commonly used in pet flea treatments.

Trelona ATBS Bait System at a Glance

Trelona Bait system is a new termite bait station from the same company that produced the well-known Advance Termite Bait Systems.

As the Advance system’s replacement, Trelona uses 0.5% Novaluron as its active ingredient. Its compressed termite bait is extremely attractive as a food source for termites, and they will quickly begin to consume it.

Great for Subterranean Termites

The bait cartridges are made with a purified cellulose-based matrix compressed into individual tablets. What sets this bait apart is how it works to eliminate subterranean termites.

The Novaluron is what’s known as a chitin inhibitor, meaning it disrupts the termites’ molting and egg production processes. Each of these stations allows for long-term, sustained consumption, as well as monitoring capabilities.

Monitor every 120 days to check for the presence of live termites.

Best For Untreated Wood: Bora-Care


  • Can be used indoors, outdoors, or for new construction

  • Simple spray application

  • Also prevents decay fungi (not mold)


  • Effective but may take up to 90 days to kill all termites

  • Termites must ingest the wood to be affected

  • Takes up to 30 days before the wood is fully soaked through

Quick Facts

Termite control in: 90 days or less

Lasts up to: Life of the wood

Active ingredient: Disodium Octaborate Tetrahydrate

Bora-Care at a Glance

This insecticide is an excellent multirole spray that kills and prevents termites, as well as acts as a strong fungicide. Bora-Care also targets other pests, such as Powderpost Beetles and Carpenter Ants.

Bora-care is specifically formulated to be used on untreated wood, differing from many other soil application termite killers. When sprayed onto untreated wood, Bora-Care seeps deep into cellulose material, such as wood-based material. It’s especially great for preventing damage on new construction.

For the Bora-Care application, spray the bottom two feet worth of studs and framework. You will need a compressed air sprayer, and the product label can help you complete your first application.

Bora-Care is different from another leading wood treatment formulation named Timbor. With Bora-Care, the thick glycol solutions allow for much deeper wood penetration than other borate products like Timbor. One treatment of Bora-Care will last for the life of the wood.

Bora-Care is a non-repellent, using borate salts to damage the bodies of termites, ants, and similar insects. When ingested by termites and other related insects, they become unable to obtain nutritional value from the food they consume, ultimately leading them to starve to death. Because of this starving mechanism, termites cannot develop a resistance.

Signs Of A Termite Infestation To Look For

Termites can be more difficult to spot than simply seeing a few crawling pests around your home. Termites are infamous for being good at hiding and difficult to find in your home.

We have compiled a list of tell-tale signs that your home is dealing with a termite infestation. Be sure to investigate or contact a professional pest control company if you notice any of these signs of termite activity.

  • Discarded Wings - Every year, termites will engage in swarming activity. During these swarming events, they all shed their wings and leave behind large amounts of these discarded wings.

  • Paint peeling - As termites tunnel through wooden structures like walls, they allow moisture into the walls. This moisture may cause peeling paint and paint bubbles.

  • Mud tubes - These are very distinguishable little tunnels that termites make along walls. They are typically about as wide as a pencil and are composed of soil and wood.

  • Frass - Tiny pellets of chewed-up woodwork are what’s known as frass. This termite excrement is a sign of a colony nearby in your home.

  • Wood that sounds hollow - When you tap on wood throughout your home, and it has a hollow ring to it, there’s a good chance it IS hollow! Termites eat up the inside of your home’s wooden structures, giving it a hollow sound when tapped.

Types of Termite Killers

There are two primary categories when it comes to termite killers - bait or liquid treatment. Liquid termiticides can be applied directly to woodwork or as a barrier around the perimeter of your home.

1. Termite Bait

Baits work by poisoning the termites and their colony. By placing poison-filled traps along the perimeter of your home, you can attract termites and let them feed on bait.

Termites are highly attracted to the cellulose, wood, or paper contained in these bait devices. Eventually, when worker ants find and consume the poison, foraging termites will carry it back to their colony, ultimately spreading and killing the entire nest.

2. Liquid Termiticides

Direct treatments and liquid barriers:

  • Direct liquid treatments

    Sometimes also known as “spot treatments,” direct liquid treatments involve drilling holes into your home’s wooden structures and injecting a foam treatment directly inside

    Alternatively, foam or spray treatments can be applied to cracks and crevices in and around the home, depending on the insecticide involved.

  • Liquid barriers

    These are applied by first digging a trench around the outside of your home. Once you’ve dug the trench, apply the liquid termite treatment to it.

    The great thing about this method is that the insecticide is non-repellent, meaning it won’t scare away termites. Foraging termites won’t notice as they walk across the poison and bring it back to their colony.

Choosing a Termite Killer: Top Points to Think About

Any termite infestation, even small, is a serious issue. However, how you go about dealing with the problem may vary depending on your home’s individual termite situation. We encourage you to examine these different points before deciding on a termite killer that best suits your home’s needs.

  • Type - liquid, foam, bait, etc

  • Severity of infestation

  • How easy the product is to use

  • Budget

  • Length of treatment required

  • Kills multiple pests or termites only

  • Time the solution remains effective

  • Effects on surrounding plants or vegetable garden

  • Harshness of the chemicals involved

  • Outdoor or indoor use

Active Ingredients In Common Termiticides

While all termite killers have active ingredients lethal to termites, the chemicals and effects vary between products. We’ll explain a little about each below.

  • Bifenthrin - Derived naturally from chrysanthemum flowers, this pyrethroid-based termite treatment stops termites' nerves from functioning properly, eventually causing them to die.

  • Disodium Octaborate Tetrahydrate - A borate compound that kills wood-destroying insects by disrupting the digestive and enzyme production systems of termites.

  • Chlorfenapyr - This broad-spectrum insecticide works by interfering with the energy production in the cells of insects, causing them to die within 72 hours.

  • Novaluron - This termiticide is what’s known as a chitin inhibitor. It controls the molting and egg development processes, eventually eliminating the entire termite colony.

  • Fipronil - This insecticide powder disrupts insects’ central nervous system and causes them to lose control of their main body functions.

DIY Termite Killers vs. Pest Control Services

  • With pests as serious as termites, it’s hard to know when to try and tackle the issue on your own or to call local pest control professionals.

  • Because termites are such a danger to the structure of homes as well as the cause of expensive repairs, many people often recommend hiring a professional exterminator.

  • There are some cases where you may not need to spend the extra money to hire such a company. Upon your initial inspection, if you uncover thorough damage or spot many termites, it’s best to call a trusted, local termite professional immediately.

  • However, if you’ve thoroughly inspected your home and have found minimal signs of termites, you can likely tackle termite infestations on your own with some of the effective treatments we’ve described here in this article.

  • With a combination of perimeter treatment, baits, and direct sprays or foams, you can control termites on your own and prevent them from coming back.
