Reviews: Top 7 Best Termite Killer for 2023 

1. Spectracide Terminate Killing Foam2 | Best foam Treatment

When it comes to foam solutions, the Spectracide Terminate Foam2 is the best termite treatment option available to you.

Spectracide Terminate Termite Killing Foam2 | Best foam Treatment View on Amazon

Foam treatment is largely used on a home’s interior by most users but is known to be equally effective when used outdoors, such as on termite nests.

However, the foam solution is considered to be mildly toxic, so you must exercise caution as you spray it around the house. The use of gloves and goggles is recommended so as to protect yourself from the foam.

Make sure to not spray it too close to food items, where your kids play frequently, or where your livestock are kept.

Apart from termites, this product is also very efficient when it comes to killing carpenter bees, as it treats the tunnels where these bees reside.

The way to use this product is to spray it into holes in your property where you feel that termites and bees may have made their home.

As you spray the foam solution on to the suspected areas (those cracks and holes in the walls), it will infiltrate and expand deep into the termites’ hideouts; the termites won’t be able to make it out alive.


  • The foam expands into cracks and voids within damaged wood
  • It comes with a detachable nozzle that makes the application into difficult-to-reach areas quite effective. You can use the nozzle to spray the foam deep within holes or termite nests


  • It may be difficult to cover large termite-infested areas as the nozzle is more geared towards accurate spraying

Boric acid is a time-tested pesticide. This simple-to-use product has been widely used to kill termites and other pests as dust or bait treatment.

Boric acid acts as a slow poison for termites and doesn’t kill them instantly on contact. Instead, the insect dies of depletion over a period of time.

It doubles down as an external pesticide, i.e., it also scrapes the exoskeleton of the termites and kills them from the outside as well. Internally, it goes on to injure their digestive tract, which will also kill them.

To use this product, simply shake the bottle, twist the cap until it opens, and then squeeze the bottle. The product should start to flow with this light pressure. If you have to apply it to hard-to-reach places, but some of it on a spoon and apply it that way.


  • It will stay with the termites as they go back into their colonies. This will allow the poison to spread to the rest of the termite population and increases the chances of killing the queen
  • It can be a multipurpose pest control solution as it works on a number of pests along with the termites


  • Pouring and applications can be an issue with this one. It can be difficult to treat a specific termite-infested area

Consideration in the Best Termite Killer – Signs

Now you know all about the different termite treatment products that you can use to get rid of a termite infestation. However, how do you know that you have termites on your property in the first place?

Apart from actually seeing the critters yourself, are there any other signs that can indicate that you have a termite infestation on your property? 

Carry out a thorough inspection yourself and look for the following signs.

  • Tiny round holes and tunnels– Termites chew holes and tunnels through wooden structures as they make their nests and feed on the wood. Any such damage or cracks should alert you to the possibility of termite presence on your property.
  • Rot – Signs of rot around the above mentioned tiny holes and tunnels should further confirm your suspicions regarding termite presence.
  • Mud tubes– These are either made of soil or the wood particles that they chew, so they can hide inside these narrow tubes and avoid detection. Clever little invaders, aren’t they? A mud tube will serve as significant proof of their presence.
  • Waste– They may be clever at hiding their presence, but they’re terrible when it comes to hiding their feces.
