How to kill flea larvae

Updated April 17, 2017

Having just one flea larvae on your pet can give the blood sucking beasts the opportunity to take over your entire home. Not only can these tiny pests cause severe skin irritation on cats, dogs and even humans, but they can also put your pet's life at risk if not treated properly. Luckily there are several steps that can be taken to remove flea larvae from your both your pets and home.

Bathe your pet using a pet-safe shampoo. Make sure all of your pet's fur is wet and then work the shampoo into a lather. Spread it all over your pet and leave it on for at least five minutes before rinsing. This will drown any flea larvae on the fur.

Create lemon juice to repeal and kill flea larvae. Slice a lemon into several wedges and pour 354ml. of hot water over the wedges. Leave the lemon soaking for 12 hours. Pour the water into a spray bottle and spray all of your pet's fur. Not only does this mixture kill flea larvae, but it also repeals them to help prevent another infestation.

Create a half-and-half baking soda and salt mixture and sprinkle it all over your carpet. The baking soda and salt will dehydrate the flea larvae that are hiding in your carpet and cause them to die. Leave the mixture on your carpet overnight and vacuum it up in the morning. After vacuuming, empty the contents of the bag outside your home.

Wash pet bedding and human bedding in hot water to drown any flea larvae that are hiding in your bedding. This should be done at least once a week until the infestation is under control.

Maintain a clean house. If you have flea larvae, you most likely have flea eggs in your home too. These eggs can hatch into flea larvae in as little as two weeks and cause your home to be infested again. In order to prevent this, vacuum your home at least once a week and mow your lawn frequently.


Never use lemon juice on pets with sensitive skin as it can cause them discomfort.
