Home Remedies for Fleas: Salt, Lemon and Baking Soda Fact Check

Social media is full of cheap flea remedies. Some help a little, some do nothing and some are unsafe for pets.

The short answer

Salt and baking soda can dry out some flea eggs and larvae in carpets and may help when vacuumed up, but they do not kill pupae or adult fleas reliably and can irritate pets if licked. Lemon spray is not proven and can irritate skin, and citrus oils can be harmful to cats. Home remedies are no substitute for vet-advised pet treatment, thorough cleaning and, if needed, professional help.

Salt

• May dry out some eggs and larvae when worked into carpets.
• Must be vacuumed up fully.

Baking soda

• Vacuum afterwards.

Lemon spray

• Not proven to kill fleas.
• Citrus oils can be harmful to cats and irritate skin.

What to do instead

1. Treat pets with vet-advised products.
2. Vacuum daily and hot-wash bedding.
3. Use professional treatment for persistent problems.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
