Holistic veterinarians advocate for safer, less toxic methods of flea and tick control, focusing on prevention, natural repellents, and environmental management. Regular Grooming: Use a fine-toothed flea comb to remove adult fleas and ticks. Bathing with Gentle Soaps: Natural soaps without harsh chemicals can help kill adult fleas on contact. Essential Oil-Based Repellents: Sprays and collars formulated with oils such as cedarwood, peppermint, thyme, citronella, and geraniol are popular among holistic vets. Diatomaceous Earth: A non-toxic powder that kills fleas by dehydrating them. Environmental Hygiene: Vacuum floors, wash pet bedding frequently, and declutter yard debris like leaves and overgrown grass where fleas and ticks may breed. Beneficial Nematodes: These microscopic organisms can be applied to lawns to feed on flea larvae and decrease populations naturally. Dietary Support: Some holistic vets recommend adding small amounts of garlic or brewer's yeast to a pet’s diet, though this should only be done under veterinary supervision.
