Dawn dishwashing soap kills fleas, and the lavender-scented version repels fleas. Dawn is also used to clean animals affected by oil spills in wildlife areas.
As opposed to using flea and tick dips that have pesticides, pet owners can choose to use a product that is the first choice for many wildlife rescue efforts. While some use it with only water, some groomers add white vinegar to result in a shinier coat. Either way, the soapy lather should be left on an animal for a few minutes to ensure that the fleas are dead. Dawn removes oils from a pet's skin, so it is important to use a conditioner afterwards.
