Termites tend to stay hidden first before spreading especially in an outdoor setting. It’s very hard to spot termites when they are in the larvae stage. However, once they grow, they are attracted to the light and become active in your garden.

Termites can be detrimental to wood structures, that’s why it’s best to destroy them. So does salt kill termites? Let’s learn all about it.

How Else Can You Kill Termites?

1. By keeping the moisture levels under control

Termites are attracted to damp places. If you are a homeowner, you need to keep watch on damp areas or wood around your yard. This can become an ideal breeding ground for termites.

In any place where moisture collects, termites will breed there in large numbers. Be sure to remove all such breeding grounds and if it proves impossible, pour a generous amount of Epsom salts in the moist areas to eliminate termites.

Remove every item that causes the ground to be too moist, especially if you live in areas that have a high likelihood of breeding termites. Keep an eye on areas that are pooling water across your garden and yard.

2. Use nematodes to kill termites

Nematodes are naturally occurring roundworms and they can kill termites. They are an effective natural insecticide because of their gut bacterium. Once a nematode enters a termite’s body, it releases bacteria that start to slowly kill it.

Nematodes are easy to find because they live in a variety of habitats. They do not cause any harm to plants, pets, or humans thus a very organic way to deal with termites. When you introduce nematodes to your garden, they will serve you for a lifetime because they will continue to multiply while keeping the termites at bay. They breed very fast and can start as fast as the first 24 to 48 hours after they are first released. Even if you are facing a huge termite threat, nematodes can kill a ton of termites and other household insects within a very short time.

3. Go for boric acid

Boric acid is available in powder form and is one of the best ways to eliminate destructive insects. This acid once ingested, complicates termites or any other insect’s digestive system eventually leading to death. This will take about 3 to 7 days for the acid to work in the insects.

Boric acid is also friendly and less toxic compared to other acids. To use it, prepare a simple concoction of boric acid powder, sugar, and water to attract the termites. Be sure to use a dust mask and goggles when preparing this mixture. The termites will start moving the boric acid back to their colony and start to die off. Add this mixture for 3 to 5 days until you cannot see any termites left.
