  3. Reduce heat and boil approximately 5 minutes.
  4. Turn off the heat and allow the lemons to steep in the water for about 8 hours (or overnight).

For this method, you should make a mixture of soap and water. This mixture can be placed in any areas where fleas have been spotted.

The soapy water will essentially act as glue and trap the fleas and it works much more effectively than simply trying to drown fleas in plain water.

While it’s very safe, it’s still a good idea to keep the mixture out of the reach of small children and pets.

#2 – Baking Soda
