Termites are a huge problem for homeowners because they can quickly infest a home and cause significant damage.

For this reason, there are many different types of treatments you can use to try and get rid of termites, but can salt kill termites? You might be surprised!

What is Salt?

Can Salt Kill Termites?

How does Salt kill Termites?

Salt kills termites by dehydrating them. Termites need a lot of moisture in order to survive, so when they come across the salt, which is 95% sodium chloride, it dries them out.

They then die from water loss. Salt can be used to kill termites because it’s the cheapest substance that has this desired effect.

Salt isn’t perfect, though. It only kills surface-dwelling termites, and it’s less effective against dry wood and damp wood termites.

The effectiveness of salt also depends on the concentration of salt and the type of wood on which the termites reside.

Salt kills ants too!

Ants may be the sworn enemy of most homeowners, but ants aren’t the only pests that salt is effective against.

If you have termites, salt can kill them too. Salt’s corrosive properties cause damage to a termite colony’s central chamber, which can lead to the death of all its inhabitants.

It’s difficult to control how much salt is placed around the house because it can be blown away or washed away.

In addition, salt doesn’t get deep into cracks and crevices where termites are more likely to be found.

However, salt does help keep back ants and other insects that will eat the honeydew that termites produce. The use of salt around the foundation of your home is a good preventive measure.

How does Rock Salt kill Termites?

Rock salt will not kill termites when it’s dry, but if they ingest it while they’re still damp, then the salt will cause them to excrete water. Soaking the termites in salty water can also kill them.
