Salt Kills Fleas

Salt can kill fleas if they are exposed to it, but it is important to use it correctly. Fleas can live for up to a month before they reach adult stage, and they can lay up to 40 eggs during this time. Salt can be dangerous to pets, so always be careful when applying it. Moreover, salt must be spread across the yard and under your house to be most effective.

Salt is an excellent desiccant, a drying agent that acts like an abrasive to destroy fleas. Fleas can hold water due to their protective outer layer known as exoskeleton, but salt damages this layer. Fleas die when the exoskeleton becomes damaged, and this is why salt kills them.

While salt can kill fleas, it can be time-consuming to apply it on all surfaces. Moreover, a lot of salt may get tracked around the home and reduce the effectiveness of the treatment. Alternatively, a pest removal company can use chemical bombs to kill fleas.

You can also use salt and boric acid to kill fleas. Boric acid can be applied without salt. To apply salt on your carpet, you need to sprinkle salt on the infested area and brush it into the rug’s fibers. It is essential to leave the mixture on the affected area for 24 to 48 hours, as the longer the treatment, the greater the chances of killing fleas.
