Yes, Apple cider vinegar can be used to kill fleas. This natural remedy has been used for centuries to repel and kill fleas and other pests. The acidic nature of apple cider vinegar is what makes it so effective. It works by disrupting the fleas' protective waxy coating, which can damage the fleas' exoskeleton and cause them to die.
To use apple cider vinegar to kill fleas, simply mix equal parts of apple cider vinegar and water in a spray bottle and spray it directly on your pet's fur. Be sure to avoid eyes, nose, and other sensitive areas. Leave the mixture on your pet for at least 15 minutes before rinsing off. You should see results within a few days, but it may take up to a week or two to completely eradicate the fleas.
In addition to killing fleas, apple cider vinegar can also be used to repel them. Adding a few drops of apple cider vinegar to your pet's water bowl can help to keep fleas away. You can also make a flea repellent spray with a mixture of apple cider vinegar, water, and essential oils, such as lavender or eucalyptus.
Overall, apple cider vinegar can be a safe and effective way to get rid of fleas. However, if you have a severe infestation, it is best to consult a veterinarian.
