Multiple studies of the past 20 years have shown ginger as a insect repeller and killer.

Although safe for dogs and humans, mint can help repell ticks and fleas due to its strong odor and compositional makeup which is toxic for insects. The menthol compounds in mint act as a natural insect repellent. Mint contains compounds like pulegone that can be toxic or irritating to ticks and fleas. When exposed to high concentrations of mint, it can disrupt their nervous systems and cause them to flee. Mint is an effective octopamine blocker, which is a key neurotransmitter in insects. Blocking octopamine can hinder the tick or flea's movement, behavior, and metabolism, leading to their death.
