About us

Our Story

It started with an allergic reaction

My dog had a severe allergic reaction to a conventional chemical flea treatment. His skin became irritated, he scratched constantly, and the vet told me something that changed everything:

"These products work, but they're pesticides. Some animals simply can't tolerate them."

That's when I decided: there had to be an alternative that wouldn't put my dog at risk. Not more effective. Not cheaper. Just safe.

Why CanISolve exists

Because you shouldn't have to choose between effectiveness and safety.

The problem

Chemical flea treatments work, but can cause allergic reactions, skin irritation, and side effects
"Natural" products on the market are vague about ingredients and rarely work
Pet owners are stuck between chemical risk and parasite infestation

Our solution

Natural formula based on essential oils with exact concentrations disclosed
Radical transparency: you know exactly what's in the collar and why
45-day guarantee to test risk-free (not 30 like others)
Effective for prevention — we don't promise miracles, we promise honesty

Let's be honest: If your pet already has a heavy infestation, you need a vet, not a natural collar.
But if you want to protect before the problem appears, without exposing your animal to chemicals every month, CanISolve was made for you.

Our approach

🔍

Radical Transparency

We publish every ingredient and its exact concentration. No vague terms like "proprietary blend" or "natural formula". If you want to know what's inside, we show you.

🛡️

45 Days To Test

We know you've tried natural products that didn't work. That's why we give you 45 days (not 30) to test on your pet, in your environment. If it doesn't work, full refund. No friction.

🐱

Separate Formulas

Dogs and cats metabolize essential oils differently. We manufacture specific versions: no concentrated eucalyptus for cats (toxic), no shortcuts. Your cat deserves safety too.

The team

CanISolve started with a personal story, but turning it into reality required an extremely competent team.

We work with specialists in natural product formulation, consulting veterinarians, and chemists who understand essential oils. We're not a "lifestyle" brand doing greenwashing — we're people obsessed with making natural products that actually work.

Every batch is tested to ensure correct concentration. Every ingredient has traceable origin. And when something doesn't work as expected, we admit it and improve — we don't hide behind marketing.

🌍

Why we sell across Europe

Because more pet owners deserve access to a safe alternative — not just those living in major capitals or with money for premium products.

The antiparasitic market is dominated by a handful of global chemical brands. They work, yes — but they also cause allergic reactions in thousands of pets every year. And most pet owners don't even know there's another option.

Our mission isn't to dominate the market. It's to give European pet owners the freedom to choose natural, transparent, and honest protection — without risking their pet's health or settling for vague products that don't work.

Are you skeptical?
Good. So are we.

That's why you have 45 days to test CanISolve on your pet, in your environment, with no risk. If it doesn't work, you get your money back. Simple as that.

Geranium Oil

Contains geraniol compound that disrupts tick and mosquito feeding behavior by masking CO2 and lactic acid signatures.

Geranium Oil contains the bioactive compound geraniol, which has demonstrated exceptional efficacy against ticks and mosquitoes in laboratory studies. This floral-scented oil disrupts the feeding behavior of blood-sucking parasites by masking the CO2 and lactic acid signatures that insects use to locate warm-blooded hosts. Its gentle formulation makes it particularly well-suited for pets with sensitive or reactive skin who cannot tolerate more aggressive treatments.

Rosemary Oil

Multi-spectrum deterrent with camphor, cineole, and alpha-pinene that disrupts insect nervous systems while enhancing skin circulation.

Rosemary Oil functions as a multi-spectrum pest deterrent, offering protection against fleas, ticks, mosquitoes, flies, and spider mites through its rich composition of camphor, cineole, and alpha-pinene. These terpene compounds interfere with the acetylcholinesterase enzyme in insects, disrupting their nervous system function. Beyond pest control, rosemary oil enhances circulation to the skin, promotes healthy hair growth, and provides powerful antioxidant protection against environmental stressors.

Citronella Oil

Creates an olfactory smokescreen that disrupts insect sensory pathways, preventing fleas, ticks, and mosquitoes from detecting your pet.

Citronella Oil works by creating an olfactory smokescreen that disrupts the sensory pathways insects use to detect hosts. The strong lemongrass-like scent emitted by citronella overwhelms the chemical receptors of fleas, ticks, and mosquitoes, preventing them from identifying your pet as a target. This botanical compound has been used for generations as a natural insect deterrent, creating an invisible protective zone around your pet without the need for synthetic pesticides.

Cedarwood Oil

Targets octopamine receptors in arthropods, causing neurological disruption in fleas, ticks, and mites while remaining safe for pets.

Extracted from the heartwood of cedar trees, Cedarwood Oil contains sesquiterpenes that target the octopamine receptors in arthropods, causing neurological disruption in fleas, ticks, and mites. Unlike mammals, insects rely on octopamine for critical functions like movement and metabolism, making cedar oil lethal to pests while remaining completely safe for pets. Beyond its insecticidal properties, cedarwood also provides a grounding, woody aroma that's naturally calming for anxious pets.

Peppermint Oil

High menthol content overwhelms insect thermal and chemical receptors while providing soothing anti-inflammatory relief to skin.

Peppermint Oil's high menthol concentration acts as a powerful neurotoxin to insects while providing soothing relief to your pet's skin. The intense cooling sensation produced by menthol overwhelms the thermal and chemical receptors that mosquitoes, fleas, and ticks use for host detection, effectively rendering your pet invisible to these parasites. Peppermint also offers anti-inflammatory benefits, reducing itching and irritation from existing bites.

Citronella Oil

Creates a vapor barrier that confuses parasitic insect navigation by emitting volatile compounds that trigger avoidance behaviors.

This botanical repellent creates a vapor barrier that confuses the sensory navigation systems of parasitic insects. By emitting volatile compounds that mimic danger signals in the insect world, citronella triggers avoidance behaviors in fleas, ticks, and mosquitoes before they ever make contact with your pet's skin.

Lemongrass Oil

Rich in citral aldehydes that block insect olfactory receptors, preventing detection of CO2, body heat, and pheromone signatures.

Rich in citral aldehydes, lemongrass oil saturates the microenvironment around your pet with compounds that block insect olfactory receptors. This "scent jamming" effect makes it impossible for biting insects to detect the carbon dioxide, body heat, and pheromone signatures they need to locate hosts. The oil's antimicrobial properties also help maintain skin barrier integrity.

Peppermint Oil

L-menthone and menthofuran compounds trigger cold-sensitive ion channels, repelling insects while soothing inflamed skin.

The L-menthone and menthofuran compounds in peppermint oil trigger TRPM8 cold-sensitive ion channels, creating an intense cooling sensation that repels insects while soothing inflamed skin. This dual action makes peppermint especially effective for pets who are already experiencing irritation from flea or tick bites, providing immediate relief while preventing further infestation.
