MAKE THE SPACE
LESS INVITING.
Selected aromatic oils can discourage certain pests from approaching or settling in treated areas. Citronella, for example, can mask scents that insects use to find a host.

PUT THE FORMULA

Some oils have demonstrated pest-killing activity after direct exposure. Seed oils and surfactants also have physical or detergent-like roles in pest control. Coverage matters: a repellent scent alone is not the same as a lethal dose.

DO ITS JOB.
Emulsifiers help oils disperse. Surfactants help a liquid wet and spread. Preservatives, antioxidants, and pH adjusters support the product in the bottle. These supporting jobs matter, too.

THE THINKING BEHIND THE BLEND.START WITH THE JOB.
START WITH THE JOB.
BUILD THE FORMULA
AROUND IT.
Trail Hound began with a family pest problem and a desire for plant-powered protection. The principle behind our lineup is practical: choose ingredients for what they contribute, then match the formula to where it will be used.
Read our family’s story- 01
A PURPOSEFUL BOTANICAL CORE.
Cedarwood, rosemary, peppermint, and other selected oils bring distinct chemical profiles and documented uses in repellency or pest control. The blend changes with the job.
- 02
A FORMULA YOU CAN APPLY.
Water, emulsifiers, and surfactants help turn concentrated ingredients into an application format. A personal spray, a household spray, and a hose-end yard treatment have different needs.
- 03
SUPPORT FOR THE WHOLE BOTTLE.
Preservation, oil stability, pH, and application feel all have a place in the formulation. A short ingredient list only helps when it contains what the product needs.
- 04
CLARITY FOR THE PERSON USING IT.
We show the actives and the supporting ingredients, explain their jobs, and distinguish the formulas. Knowing what is inside helps you choose and use a product thoughtfully.

Botanical activesCedarwood oil
Botanical repellency + contact activity
Cedarwood oil contains aromatic compounds, including cedrol in some oils. USDA laboratory work on a particular cedarwood oil demonstrated tick repellency and tick mortality after exposure to treated surfaces. That makes it more than a woodland scent: it has a documented pest-control role.
Why it’s in the formula
It provides the botanical foundation for several of our pest-control blends. In Deep Clean, cedarwood is part of the grooming formula; that shampoo should not be substituted for a labeled flea-and-tick product.
Find it in
Trail Guard OriginalTrail Guard LemongrassTrail Guard TravelTrail Guard MaxTrail DefenseHome GuardHome Guard MaxYard / Lawn GuardRodent GuardDeep Clean Dog Shampoo
The USDA study tested a specific oil, not our finished products. Results varied by tick species, dose, and exposure time.
Read the ingredient research ↗Botanical activesRosemary oil
Aromatic botanical repellent
Rosemary oil contains volatile compounds such as 1,8-cineole and camphor. It is used as a botanical repellent; laboratory research has also observed contact activity against certain insects. Its role is functional as well as aromatic.
Why it’s in the formula
It brings another botanical active to our cedarwood + rosemary blends and to Woodland Citrus. Different oils contribute different chemical profiles to a formula.
Find it in
An oil’s composition and the complete blend affect results; an ingredient study does not establish a finished product’s protection time.
Read the ingredient research ↗Botanical activesPeppermint oil
Repellency + pest-control activity
Peppermint oil supplies menthol and other aromatic compounds. Published ingredient research describes both repellent properties and activity against certain insects and mites. In Rodent Guard, its job is to contribute to repellency, not to kill rodents.
Why it’s in the formula
It anchors the mint-forward Home Guard family and the aromatic Rodent Guard blend.
Find it in
Home and rodent formulas are for labeled treatment areas, not direct application to pets or people.
Read the ingredient research ↗Botanical activesCitronella oil
Personal insect repellency
Citronella can help mask scents that insects use to locate a host. Its main job is to repel insects, rather than kill them. It is one of the aromatic oils in our Woodland Citrus blend.
Why it’s in the formula
It contributes a recognized repellent ingredient to Trail Defense’s personal-protection formula.
Find it in
Protection duration depends on the complete formula, application, and conditions. Citronella alone does not establish a number of protection hours.
Read the ingredient research ↗Botanical activesLemongrass oil
Citral-rich botanical active
Lemongrass oil is rich in citral. Laboratory studies have demonstrated repellent and contact effects against particular insects, including ants. It also contributes the bright herbal-citrus character of a blend.
Why it’s in the formula
It gives Trail Guard’s lemongrass variation its distinct botanical profile and joins the multi-oil Woodland Citrus blend in Trail Defense.
Find it in
The cited ant study is ingredient evidence, not a test of our products or a guarantee against every pest.
Read the ingredient research ↗Botanical activesSesame oil
Plant seed oil with contact-control uses
Sesame oil is a seed oil used as a pesticide active. Its documented uses include physical, suffocating action against susceptible insects and use alongside other active ingredients. Contact and coverage are important to those uses.
Why it’s in the formula
It adds a seed-oil component to selected Trail Guard, Trail Defense, and outdoor blends.
Find it in
Trail Guard OriginalTrail Guard LemongrassTrail Guard TravelTrail Guard MaxTrail DefenseYard / Lawn Guard
Its presence does not prove a longer-lasting barrier or a specific synergy in the finished product.
Read the ingredient research ↗Formula supportCoconut-derived SLS powder
Surfactant + labeled pesticide active
SLS stands for sodium lauryl sulfate. It reduces water’s surface tension, helping a liquid wet and spread, and supports ingredient dispersion. It also has a history of detergent-like flea-and-tick control in formulated products and is listed as an active on several of our spray labels.
Why it’s in the formula
We use coconut-derived SLS powder as a functional raw material in selected formulas. It is incorporated into the liquid during formulation; “powder” describes the starting ingredient, not a dust you apply.
Find it in
Trail Guard OriginalTrail Guard LemongrassTrail Guard TravelTrail Guard MaxHome GuardHome Guard MaxYard / Lawn Guard
SLS is processed from its raw materials. It is different from sodium laureth sulfate (SLES), and coconut origin alone does not make it non-irritating. Trail Defense and our sulfate-free Deep Clean shampoo do not list SLS.
Read the ingredient research ↗Botanical activesEugenol
Aromatic component in the rodent blend
Eugenol is an aromatic compound associated with clove oil and other botanicals. It contributes a warm, spicy component to Rodent Guard’s repellent blend.
Why it’s in the formula
It adds a different aromatic profile alongside peppermint, cedarwood, and cinnamon. Rodent Guard’s intended job is deterrence, not poisoning rodents.
Find it in
Botanical activesCinnamon leaf oil
Aromatic component in the rodent blend
Cinnamon leaf oil supplies a concentrated spicy botanical aroma. It is one of the oils listed in Rodent Guard’s aromatic formulation.
Why it’s in the formula
It broadens the blend’s aromatic profile. Its use belongs to the labeled space-treatment formula, not a skin or pet-care application.
Find it in
Formula supportWater
Liquid carrier
Water provides the liquid base for our sprays and shampoo. It carries the other ingredients so a measured amount can be applied and distributed.
Why it’s in the formula
A water-based carrier makes a formula practical to spray or rinse. Water itself is not the pest-killing active.
Find it in
Formula supportPolyglyceryl oleate
Emulsifier
Oils and water naturally separate. Polyglyceryl oleate helps them disperse together in the liquid, making it easier to distribute the oil ingredients through an application.
Why it’s in the formula
A usable blend needs more than oil plus water. This ingredient supports the emulsion; follow the label’s shake-before-use directions.
Find it in
Formula supportGlycerin
Humectant + formulation support
Glycerin attracts water and helps with moisture retention. It also contributes to the feel and body of a water-based formula.
Why it’s in the formula
It supports the application experience in selected sprays and the moisture-focused grooming blend. It is not included as a pest-killing active.
Find it in
Formula supportVitamin E / tocopherol
Antioxidant for oils
Tocopherol helps slow oxidation of oils, supporting the quality of oil-containing formulas. In the balm, it sits alongside the conditioning oils and butters.
Why it’s in the formula
Oil ingredients need support during storage, too. Vitamin E is an antioxidant; it does not replace a preservative system for a water-based product.
Find it in
Formula supportPotassium sorbate
Preservative
Potassium sorbate helps protect a water-containing formula from microbial spoilage, particularly yeast and mold. Its function depends on factors including pH and the rest of the preservative system.
Why it’s in the formula
It helps preserve the product in the bottle. It is not the ingredient used to control fleas, ticks, or household insects.
Find it in
Formula supportSodium benzoate
Preservative
Sodium benzoate helps protect water-based formulations from microbial spoilage. It is used alongside other formulation ingredients, with pH affecting its performance.
Why it’s in the formula
It supports product preservation during normal storage and use. Preserving a bottle is a different job from killing pests.
Find it in
Formula supportCitric acid
pH adjustment
Citric acid is used to adjust a formula’s acidity. pH matters to the overall formulation and to how some preservatives function.
Why it’s in the formula
It helps bring the liquid into the intended formulation range. Its presence is not a claim that the product disinfects surfaces or treats skin conditions.
Find it in
Formula supportCastor oil
Supporting plant oil
Castor oil is a thicker plant oil included in the Rodent Guard formulation. It contributes to the oil phase and the physical character of the blend.
Why it’s in the formula
It supports that specific formulation. We do not treat its presence as proof of a particular residual protection time.
Find it in
Skin & coat careBeeswax
Balm structure + surface barrier
Beeswax gives the balm its solid structure and helps leave a protective coating on the paw surface.
Why it’s in the formula
A paw balm needs to stay where it is applied while keeping oils and butters in an easy-to-use format.
Find it in
Skin & coat careShea oil
Emollient oil
The liquid oil fraction from shea contributes softness and spreadability to the balm.
Why it’s in the formula
It balances the firmer waxes and butters so the blend can be worked onto paw pads.
Find it in
Skin & coat careGreen tea seed oil
Conditioning seed oil
Also listed as Camellia sinensis seed oil, this is an emollient oil from the tea plant’s seeds. It is different from a brewed green tea or leaf extract.
Why it’s in the formula
It contributes to the balm’s conditioning oil blend and helps soften the feel of dry paw surfaces.
Find it in
Skin & coat careCoconut oil
Emollient + balm texture
Coconut oil adds conditioning lipids and contributes to the consistency of the balm.
Why it’s in the formula
It helps balance the blend’s firmness and glide. Coconut oil in a balm is a different ingredient from coconut-derived SLS in a spray.
Find it in
Skin & coat careShea butter
Rich emollient + body
Shea butter contributes a soft, rich texture and helps reduce moisture loss from the skin surface.
Why it’s in the formula
It gives the balm substance while complementing the lighter conditioning oils.
Find it in
Skin & coat careCalendula-infused olive oil
Botanical conditioning oil
Calendula is carried in an olive-oil base. The oil supplies emollience and spreadability in the paw balm.
Why it’s in the formula
It brings a botanical-infused oil to the care blend. We describe its conditioning role without promising to heal wounds or treat disease.
Find it in
Skin & coat careJojoba seed oil
Liquid wax emollient
Although called an oil, jojoba is composed largely of liquid wax esters. It helps lubricate and soften the skin surface.
Why it’s in the formula
It contributes glide and a smooth application alongside beeswax and shea butter.
Find it in
Skin & coat careTurmeric essential oil
Aromatic botanical in the balm
Turmeric essential oil is part of the balm’s botanical blend. It is distinct from turmeric powder or a standardized curcumin supplement.
Why it’s in the formula
It contributes an aromatic botanical component. Its presence is not a claim of pain relief, anti-inflammatory treatment, or wound healing.
Find it in
Skin & coat careGinger essential oil
Aromatic botanical in the balm
Ginger essential oil contributes a warm aromatic note to the balm’s oil blend.
Why it’s in the formula
It is part of the product’s botanical profile. The finished balm is for external paw care, not an edible product or medical treatment.
Find it in
Skin & coat careCoconut-derived surfactant
Rinse-off cleanser
A surfactant helps water lift and rinse away dirt and oils from a dog’s coat. Deep Clean’s label identifies its cleanser in this way without naming the individual surfactant.
Why it’s in the formula
It provides the cleansing action in our current grooming shampoo. The label identifies Deep Clean as sulfate-free; do not confuse this ingredient with the SLS used in selected sprays.
Find it in
Skin & coat careColloidal oatmeal
Skin-conditioning ingredient
Finely processed oatmeal is dispersed through the shampoo as a skin-conditioning ingredient.
Why it’s in the formula
It is part of the moisture-focused grooming blend for washing the coat and caring for the skin beneath it.
Find it in
Skin & coat careCentella asiatica extract
Botanical skin conditioner
An extract from the Centella asiatica plant, included in the shampoo’s botanical care blend.
Why it’s in the formula
It complements the other conditioning ingredients. Its inclusion does not establish a treatment for skin disease or a hair-growth claim.
Find it in
Skin & coat careCalendula extract
Botanical skin conditioner
Calendula extract is included in the water-based shampoo. It is a different ingredient preparation from the calendula-infused olive oil in the balm.
Why it’s in the formula
It adds a botanical conditioning component to the rinse-off grooming formula.
Find it in
Formula supportPhenoxyethanol
Shampoo preservative
Phenoxyethanol helps protect the water-based shampoo from microbial contamination during storage and use.
Why it’s in the formula
The grooming formula uses a preservative system suited to that product. Plant ingredients and water still need preservation.
Find it in
Formula supportEthylhexylglycerin
Preservative-system support
Ethylhexylglycerin is paired with phenoxyethanol in Deep Clean’s ingredient list and supports the preservative system.
Why it’s in the formula
It helps support the formula’s preservation and is distinct from the separate glycerin ingredient.
Find it in
Skin & coat careVitamin B5 / panthenol
Skin & coat conditioning
Panthenol is a humectant and conditioning ingredient used to support moisture and the feel of the coat.
Why it’s in the formula
It complements the cleanser with a grooming-care function.
Find it in
Skin & coat careGuar hydroxypropyltrimonium chloride
Coat-conditioning polymer
This modified guar ingredient helps condition the coat and improve slip during washing and grooming.
Why it’s in the formula
It supports the feel and manageability of freshly washed fur.
Find it in
Skin & coat careFragrance
Shampoo scent
Fragrance contributes to Deep Clean’s Rustic Woods scent. It is listed separately from cedarwood essential oil on the product label.
Why it’s in the formula
It shapes the grooming experience. A fragrance ingredient is not, by itself, a flea-and-tick treatment.

THE DIFFERENCE IS IN THE FORMULA.WHAT MAKES
WHAT MAKES
MAX, MAX?
Max increases selected active-ingredient concentrations compared with the corresponding Original. Here is what changes in our two established Max blends.
Trail Guard
ORIGINAL9.5%
MAX13.5%
Total listed active ingredients in the bottle
| Active ingredient | Original | Max |

| Rosemary oil | 1.5% | 2.5% |
| Coconut-derived SLS | 2.5% | 2.0% |
| Sesame oil | 1.0% | 1.0% |
Max raises cedarwood and rosemary while adjusting SLS. It is not simply more of every ingredient. Trail Guard Max is not for cats.
Home Guard

| Coconut-derived SLS | 2.5% | 3.5% |
Max increases all three listed actives. Both formulas are for labeled household treatment areas, not direct use on people or pets.
MORE CONCENTRATED IS A FORMULA DIFFERENCE.
It is not a percentage improvement in effectiveness, a promise of longer protection, or permission to apply more. Compare matching product families and follow each label. A hose-end yard concentrate also should not be compared directly with a ready-to-use personal spray.
A BOTANICAL ALTERNATIVE. AN INFORMED CHOICE.THOUGHTFUL INGREDIENTS.
THOUGHTFUL INGREDIENTS.
THOUGHTFUL USE.
We build our pest-control sprays around selected botanical oils and clearly identified supporting ingredients. That gives you a plant-based alternative to consider alongside conventional synthetic products.
Safety depends on the finished formula, concentration, exposure, and the person, animal, or place being treated. Natural origin alone does not establish that a product is safer than a synthetic alternative. A meaningful comparison needs evidence for the specific products and uses.
START WITH THE RIGHT LABEL.
Personal, pet, household, and yard formulas have different directions. Home Guard and yard treatments are not for direct application to pets or people. Trail Guard Max is not for cats.
USE THE INTENDED AMOUNT.
Follow application, dilution, drying, and reapplication directions. Extra product is not a substitute for good coverage or choosing the correct formula.
MAKE IT PART OF THE ROUTINE.
Pair the right product with practical habits: regular tick checks, clean pet bedding, and attention to the spaces where pests gather.
