Does Salt Kill Fleas?

One of the most common DIY flea killing methods is applying salt to the area in which the fleas are hiding. While salt doesn’t necessarily kill fleas, it can kill adult fleas and prevent them from hatching. This method isn’t recommended for indoor use. While it is effective against active adult fleas, it’s not effective against flea eggs or flea pupae in cocoons.

When you apply salt to the furniture and carpet in your home, you must cover the affected areas with clothing. For maximum effectiveness, you should apply the salt at night before you sleep. In addition, you must vacuum the area in the morning after applying the salt. Salt may leave a sticky residue, so be sure to keep the area dry.

Salt can kill fleas by causing dehydration. However, this method may not be 100% effective. Flea larvae are unable to lay eggs until they have blood. Therefore, the best way to kill fleas is to apply a salt solution periodically to the affected area.

Salt has several beneficial properties. It can kill adult fleas and larvae by dehydrating the environment. It also serves as an abrasive, causing damage to the exoskeleton of fleas. In addition, salt can kill young flea larvae.
