How Can I Use Salt To Kill Fleas?

If you are suffering from a wave of unwelcome house guests in the form of fleas, you can use any of the following methods using your usual household table salt to remove them.

  • The use of salt is great for large areas such as carpets and area rugs as the product can be simply sprinkled on and left to work its magic. You can also do this in other areas of the home such as on soft furnishings and bedding.
  • As you are probably well aware, most of the flea infestation can be found on your pet and so it is highly important to treat them with salt too. In order to have the most success from the salt treatment, you should give you pet a salt bath.
  • This can be achieved by mixing salt and water (one part salt to ten parts water) in a suitable container such as a basin or bath tub.

You can then bathe your pet in the water paying particular attention to areas where the fleas are most dense, for example behind the ears.

After the salt bath, you can then brush your pet and allow the salt to take action. Read Also: Do Fleas Stay On Humans?

  • Thoroughly vacuum the area before beginning the treatment as this will remove some of the eggs first.
  • The best way to tackle a room is to begin at the door and work inwards to stop any of the fleas from getting out.
  • Make sure that you evenly spread the salt around the area you are dealing with.
  • Using a brush to work the salt through the carpet will further encourage its ability to dry out the fleas.
  • You should leave the salt for as long as possible with 48 hours being the minimum amount of time.
  • To remove the salt, thoroughly vacuum the room once again.

What about Flea Eggs, Does Salt Work For Those Too?

One of the major points of concern when trying to rid your home of fleas are their eggs. These are notoriously difficult to get rid of and can often be a source of the infestation returning.

But can salt assist you in the removal of the eggs as well as the live pests? In short, the answer to this question is a resounding yes! The salt will act in the same way as it does with the adult fleas and will dry out any eggs, causing them to die off before they have the chance to hatch.

More often than not, the majority of the flea eggs will fall off their host once they have been laid and will remain around the home-in carpets and nooks and crannies until they develop into adult fleas which then reattach to the host and the process begins again.
