Banish – Bioactive Bites

Banish is a natural pest and parasite repellent supplement designed to provide chemical-free defence against fleas, ticks and internal worms. It works through eight complementary mechanisms, creating an internal and external environment that parasites actively avoid, without the neurotoxic compounds in conventional spot-on treatments. It is formulated for preventative use and ongoing protection rather than as a treatment for active heavy infestations.

Banish works through two primary pathways. Externally, cold-processed essential oils including Clove Leaf, Lavender, Thyme and Rosemary create a volatile aromatic profile that flea and tick sensory systems register as repellent, deterring them from settling and feeding. Internally, B-vitamin compounds from brewer’s yeast support the excretion of sulphur-containing metabolites through the skin, creating a systemic chemical profile that ectoparasites avoid. Both pathways work best with consistent daily use.

Banish is a natural preventative supplement, not a licensed veterinary antiparasiticidal treatment. For dogs in very high-risk environments or with active heavy infestations, conventional veterinary treatments may be necessary as the primary control measure, with Banish providing supplementary natural support. For dogs in lower-risk environments or owners seeking a chemical-free preventative approach, Banish is designed for this primary use. If you are unsure about your dog’s parasite risk level, consult your vet.

The essential oil repellent compounds begin working from the first dose. The deeper systemic repellent effect from brewer’s yeast B-vitamins and sulphur compounds builds over two to three weeks as they accumulate in skin secretions to optimal levels. For maximum protection, begin Banish at least two to three weeks before the start of peak flea and tick season and maintain consistently year-round.

Banish supports internal resistance to worms through pumpkin seed flour’s cucurbitacin content and through prebiotic support for a gut microbiome less hospitable to parasitic colonisation. Banish is not a licensed veterinary anthelmintic and is not a replacement for prescription worming treatments, particularly for known infestations or dogs in high worm-challenge environments. It provides a natural supplementary layer of internal resistance.

Banish is the pest and parasite repellent supplement: it creates conditions that deter fleas, ticks and worms from establishing on and in your dog. Block is the allergy and skin health supplement: it addresses the immune dysregulation, skin inflammation and gut-skin axis imbalance that drives allergic reactions to environmental triggers including flea bites, pollen and food. For dogs with flea allergy dermatitis, using Banish and Block together is the most comprehensive approach.

The recommended dose is 1 chew per 10kg of body weight per day. A 10kg dog gets 1 chew daily, a 20kg dog gets 2 chews, and dogs over 30kg get 4 chews daily. Each chew can be given as a treat or broken into pieces over food. Consistency is particularly important for Banish: the internal repellent effect depends on a daily supply of active compounds being maintained in skin secretions.

Banish can be given at any time of day with food. Establishing a consistent daily routine is especially important for Banish, as the systemic repellent compounds rely on continuous daily provision to stay at effective concentrations. We recommend starting at least two to three weeks before peak flea and tick season to allow the internal effect to build before exposure increases.

Banish chews are formulated to be palatable and are accepted by the vast majority of dogs. For fussy eaters, breaking into smaller pieces and mixing with food works well. If your dog does not take to them, our Happiness Guarantee means you can return your first order for a full refund: no questions asked.

Yes. Banish is designed for daily, year-round preventative use. All ingredients are included at safe, supplemental levels and the formulation has been developed by a qualified canine nutritionist. The essential oil components are cold-processed and delivered at levels appropriate for daily oral use, distinct from the concentrated topical applications where essential oil safety concerns arise.

Banish is well-tolerated by the vast majority of dogs. Some dogs may experience mild digestive adjustment in the first few days as the gut microbiome responds to the probiotic and prebiotic compounds. The essential oil components are included at safe supplemental levels and the cold extrusion process ensures they are delivered in a form appropriate for daily oral use.
