CORE Flea + Tick Kill + Repel is a plant-based pest-control spray made to help protect cats, dogs, kittens and other animals from fleas, ticks and unwanted bugs.

The formula can be applied directly to your pet's fur and used throughout the areas where they sleep, play and relax, including bedding, carpets, furniture, patios and outdoor pet spaces.

Cedarwood, geranium and rosemary essential oils work together to help kill and repel pests while giving the formula a fresh botanical scent instead of the overpowering smell associated with many conventional pest sprays.

Plant-Based Formula Direct-to-Fur Use Kills + Repels Pet + Home Use Developed in the USA

Fleas and ticks do not stay in one place. They can move between your pet's coat, bedding, carpets, furniture and outdoor resting areas, which is why treating only one surface may not be enough.

CORE is designed to protect both your animals and the spaces they use most. Spray it directly onto fur as directed, then use it around bedding, furniture, carpets, cat trees and outdoor pet areas as part of a consistent pest-control routine.

The controlled sprayer delivers a light, even mist, helping you cover the coat and surrounding surfaces without excessive dripping, puddling or wasted product.

  • Helps kill and repel fleas, ticks and unwanted bugs
  • Helps target adult pests, eggs and larvae
  • Can be applied directly to your pet's fur as directed
  • Suitable for cats, dogs, kittens and other animals when used as directed
  • Can also be used on bedding, carpets, furniture and pet areas
  • Made with cedarwood, geranium and rosemary essential oils
  • Made without harsh synthetic pesticides
  • Controlled, drip-free sprayer for a light and even application
  • Cedarwood Oil A plant-based ingredient traditionally used as a natural pest deterrent, with a warm and grounding botanical scent.
  • Geranium Oil Adds a fresh floral character while supporting the formula's overall flea, tick and bug-control blend.
  • Rosemary Oil Provides a clean herbaceous scent and helps round out the plant-based pest-control formula.
Essential oils are concentrated, so a light and even application is recommended. More product does not necessarily mean better coverage.
  • Directly on fur: Apply a light, even mist to your pet's coat as directed.
  • Pet bedding: Treat beds, blankets and sleeping areas where pests may hide.
  • Carpets and rugs: Apply lightly to fibers, edges and other pet-accessible areas.
  • Furniture: Use on sofas, chairs and upholstery shared with pets.
  • Cat trees and scratching posts: Treat high-contact pet furniture as directed.
  • Outdoor pet areas: Use around patios, kennels and other spaces where animals spend time.

For direct use on pets: Apply a light, even mist to the coat, including the back, belly, legs and other pest-prone areas. Work the product through the fur as directed so it reaches the coat evenly.

For pet-area surfaces: Lightly spray bedding, carpets, furniture, cat trees and outdoor pet areas. Avoid soaking or saturating fabrics and surfaces.

Use in a well-ventilated area and allow treated surfaces to dry before your pet returns to them. Repeat according to the complete directions printed on the bottle.

Avoid spraying directly into the eyes, nose or mouth. For facial areas, apply the product to your hands or a cloth first, then carefully work it into the fur while avoiding sensitive areas.

CORE is designed to fit into a consistent flea and tick prevention routine rather than being used only after a major pest problem appears.

Reapply according to the product label, particularly during flea and tick season, after bathing, or when your pet spends time in higher-risk outdoor environments.

Regularly treating your pet and the spaces they use most can help reduce the areas where pests, eggs and larvae may remain.

Use only as directed and begin with a light application. Essential oils are concentrated and should not be over-applied.

Use in a well-ventilated area. Avoid direct contact with the eyes, nose, mouth and other sensitive areas. Do not allow animals to ingest the product.

Allow treated bedding, furniture, carpets and other surfaces to dry fully before animals or children return to the area.

If your pet has a known sensitivity, is receiving veterinary treatment, or reacts unexpectedly after application, discontinue use and contact a veterinarian.

Always follow the complete instructions and warnings printed on the product bottle.

We want you to feel confident trying CORE Flea + Tick Kill + Repel. If you are not satisfied with your order, contact our support team within the return period listed in our store policy.

Our team will review your request and provide the next available step according to the terms of our return and refund policy.

Use only as directed. Product performance may vary based on the animal, environment, pest pressure and consistency of application. Always follow the complete directions and safety information printed on the bottle.

The scratching finally started calming down

My cat started scratching constantly, and I knew I needed to act before fleas spread through the rest of the house. I sprayed her coat as directed and also treated her bedding and favorite chair. It was easy to use and fit naturally into our cleaning routine.

A must-have in our multi-dog home

With several dogs running between the yard, furniture and their beds, I wanted one product I could use throughout the places they actually spend time. I use CORE on their coats and around the house, especially during warmer months when fleas and ticks become a bigger concern.

I feel better using this around my kitten

Finding flea products for a home with a kitten was frustrating. I wanted something plant-based that I could apply carefully and also use on the bedding and cat tree. The sprayer gives a light, controlled mist instead of soaking everything.

Much easier than treating everything separately

I used to buy one product for the dog, another for bedding and something else for the carpet. CORE makes the routine much simpler. I can treat my dog's coat, bed, sofa and the areas near the back door without switching between several different sprays.

No heavy chemical-cloud smell

The thing I noticed first was the botanical scent. It does not have the harsh smell that made me avoid using other sprays inside the house. I still ventilate the room and follow the directions, but the whole routine feels much more manageable.

Staying ahead of flea season feels easier

I learned the hard way that waiting until you see several fleas is already too late. Now I use CORE as part of a consistent routine on my pets and the places they sleep. It gives me peace of mind knowing I am treating more than just one area.

One Simple Pet + Home Spray

Protect More Than
Just Their Fur.

CORE helps kill and repel fleas, ticks and unwanted bugs directly on your animals and throughout the places where they sleep, play and relax.

Apply a light, even mist directly to your pet's coat as directed, including the back, belly, legs and other pest-prone areas. The controlled sprayer helps distribute the formula without heavily saturating the fur. Use on: Cats, dogs, kittens and other animals as directed
Fleas and ticks can move between your pet and their surroundings. CORE can also be used on pet bedding, carpets, rugs, furniture, cat trees, patios and outdoor pet areas as part of a more complete protection routine. Use areas: Fur, bedding, carpets, furniture and outdoor spaces
CORE is formulated with cedarwood, geranium and rosemary essential oils. Together, they provide plant-based pest-control support with a fresh botanical scent rather than the overpowering smell of many conventional sprays. Key ingredients: Cedarwood, Geranium and Rosemary Oils
The included trigger sprayer is designed to deliver a fine, targeted mist. This makes it easier to apply a light coat to fur and surfaces without dripping down the bottle, creating puddles or wasting unnecessary product. Sprayer benefit: Even mist with targeted control
