Termites got their name from the Latin word “termes”, which means woodworm as they like to eat wood and everything else that contains cellulose. One colony consumes up to 450 kg of wood a year! That’s why they can cause so much damage to homes and other structures made of wood.

We reviewed dozens of options before narrowing our list down to the 5 best termite sprays on the market today. Our favorite is the Termidor SC. We considered the active ingredients since they affect the effectiveness of a spray. Some of the most effective active ingredients include bifenthrin, lambda-cyhalothrin, and fipronil. The best termite spray also will have a long-lasting formula that is easy to apply.

Editor’s Choice

Termidor SC

Features
  • Active ingredient:  fipronil 9.1%
  • Use:  outdoors
  • Volume:  4 fl. oz.
  • Lasts for: 10 years
  • Time to kill: not specified

Termidor SC is our Editor’s Choice because it is a powerful termiticide that kills termite colonies and prevents new colonies from forming. It uses 9.1% fipronil to kill insects by attacking their central nervous system. One bottle of Termidor SC can be used to treat up to 16,600 sq. ft., making it an incredibly cost-effective solution. The product also lasts for 10 years, so you can rest assured that your home will be protected from termites for a long time.

Termidor SC is usually compared to the Navigator SC, as both feature 9.1% fipronil and are effective termite control products. With these two, the termites can’t detect their product. But, the Termidor SC is better suited for a serious infestation, as it will be transferred to others in the colony. This makes it easy to spread the termite killer throughout the colony.

    Why is it special?
  • Long-lasting;
  • Highly effective;
  • Kills a wide range of insects;
  • One bottle can be used to treat up to 16,600 sq. ft.;
  • Pet safe;
  • Non-repellent.
    What are the flaws?
  • Requires a sprayer.

Taurus SC Termiticide

Features
  • Active ingredient: fipronil 9.1%
  • Use: outdoors
  • Volume:  20 fl. oz.
  • Lasts for: 10 years
  • Time to kill: not specified

Looking for a powerful and long-lasting termite spray? Look no further than Taurus SC Termiticide.

Taurus SC Termiticide works like the Termidor SC, with 9.1% fipronil. Both act like non-repellants and will spread through the colony. But, the Taurus SC has a wide range of applications aside from a termite killer. It can be used as a barrier to keep termites away aside from killing them.

    What stands out?
  • Non-repellent;
  • Long-lasting;
  • Works on a wide range of insects.
    What cons did we manage to find?
  • For outdoor use only;

Things to Consider

Termites are attracted to wood, paper, and other materials that contain cellulose. When they find a food source, they set up colonies and start eating away at the wood. This can cause serious damage to homes and other structures as well as furniture and other wooden items. Colonies can contain up to several million termites, so it’s important to get rid of them as soon as possible.

About Termites

Termites are small, winged insects that are related to cockroaches. They live in colonies underground and travel to find food.

While most people think of termites as pests, there are actually some benefits to having them around. Termites aerate the soil and help recycle dead wood and other plant material. They also provide food for many animals, including birds, lizards, and rodents. However, when termites invade homes and other structures, they can become a serious problem.

There are more than 2,000 species of termites, and they can be divided into two main groups: subterranean and drywood.

Subterranean termites are the most common type in the United States. They live in colonies in the ground and build mud tunnels to reach above-ground food sources.

Drywood termites are less common but can cause just as much damage. They live in dry, wooded areas and don’t need to build mud tunnels. Our article will tell how to get rid of drywood termites with termite sprays.

Signs of Termites

5 Best Termite Sprays to Stop These Devourers (Winter 2023)
Termites can be hard to spot because they live underground or inside the wood. However, if you know what to look for, you can spot the signs of termites in your home or business.

There are a few different ways to tell if you have a termite problem and need to take action.

Mud tubes: The first sign of a termite problem is usually mud tunnels on the outside of your home. These are used by termites to travel between their colony and food source.

Discarded wings: Termites shed their wings when they mate. If you find wings near your home, it’s a good indicator that you have a problem.

Hollow-sounding wood: Termites eat the soft center of the wood, leaving only the hard outer shell. This can make the wood sound hollow when tapped.

Swarms: Some types of termites swarm in the spring to mate and start new colonies. If you see a swarm of insects near your home, there’s a good chance they are termites.

Cracks in paint or wood: Termites can cause paint or wood to crack as they travel behind it and eat the wood. You can also see termite holes on wood.

Why Choose Termite Spray

Termite sprays are the answer to the question of how to get rid of flying termites. They are the most effective way because they kill insects quickly. Termite baits can take months to work and might not be as effective, and termite traps only catch a small number of termites.

How to Use Termite Spray

First, you need to identify all of the areas where termites might be entering your home. These are usually around doors and windows, cracks in the foundation, and any other areas where there are wood and cellulose materials.

The best time to apply termite spray is in the spring before termites start swarming. This will give the spray time to work and prevent termites from entering your home.

Once you have identified all of the potential entry points, you need to apply the termite spray around these areas. Make sure to follow the instructions on the label so that you apply it properly.

It’s important to reapply the termite spray every few months to make sure that your home is protected.

You will usually need to mix it with water and apply it with a pump sprayer. Be sure to wet the ground around your home and any cracks or crevices where termites might be entering.

Important Features

If you think you have a termite problem, it’s important to take action immediately. The sooner you treat the problem, the less damage termites will cause. There are a few different ways to get rid of termites, but the most effective way is to use a termite spray. A good termite spray will have a long-lasting formula that is easy to apply. It should also contain a residual effect, which means it will continue to kill termites even after the initial application.

Active ingredients

Active ingredients are the key to any effective pest control product, whether it’s a termite spray or another type of pesticide. The EPA (Environmental Protection Agency) regulates all pesticides, and each one has to list its active ingredients on the label.

Fipronil is the most common active ingredient in termite sprays. It works by disrupting the nervous system of insects, causing them to die. Fipronil-based sprays provide long-lasting protection against termites.

Bifenthrin is another common active ingredient in termite sprays. It works by paralyzing and killing insects that come into contact with it. It’s a good choice if you want a fast-acting termite spray.

Deltamethrin is derived from pyrethrin, a natural insecticide. It works by causing paralysis and death in insects. You can opt for it if you are looking for a natural-based termite spray.

Boron is a naturally occurring element that is toxic to insects. It works by causing dehydration and death in termites. It is a good choice for those who want an organic termite spray.

Formulation

The formulation is an important consideration when choosing a termite spray. Concentrated formula will contain a higher concentration of the active ingredient than a diluted formula.

Use

When choosing a termite spray, it’s important to read the label carefully.

Some products are only for outdoor use since they can be harmful to humans and pets if used indoors. They usually contain more active ingredients.

Others can be used both indoors and outdoors. Make sure to choose a product that can be used in the area you need it.

Time it takes to work

The time it takes for a termite spray to work depends on the active ingredient. Some ingredients work quickly and will kill termites on contact. These include bifenthrin and deltamethrin. Others, like fipronil, take days or weeks to work but will provide long-lasting protection.

Lasting power

The lasting power of a termite spray also depends on the active ingredient. Some ingredients will last for months like fipronil, while others may only last for days or weeks.

Most termite sprays need to be applied every few months to be effective.

This is because they only kill the insects that come into contact with them. Reapply the spray according to the label instructions to keep termites away.

Toxicity

Some termite sprays are more toxic than others. If you have children or pets, you may want to choose a less toxic option.

Organic options are available that use natural ingredients like boron and essential oils. These are safer for humans and pets but may not be as effective as synthetic options.

Safety Tips

5 Best Termite Sprays to Stop These Devourers (Winter 2023)
Safety is a key consideration when using any pesticide because it contains toxic chemicals that can cause health problems if inhaled or ingested.

When using any chemical product, it’s important to follow the label instructions. This will help you stay safe and use the product correctly.

Wear gloves and a mask when applying the spray. If you get the spray on your skin, wash it off immediately.

Do not use the spray near food or water. Store it in a safe place where children and pets cannot reach it.

If you’re using an indoor spray, make sure to ventilate the area. Open windows and doors to let fresh air in.

FAQ

Can vinegar kill termites?

No, vinegar will not kill termites. It only repels them.

Do termite sprays expire?

Yes, most termite sprays have a shelf life of 2-5 years. After that, they may not be as effective.

Can I use a termite spray indoors?

Yes, but you need to choose a product that’s labeled for indoor use. These products usually have less active ingredients and are safer to use indoors.
