Science-Backed Protection

Formulated based on neuroscience research into rodent trigeminal nerve response and pheromone navigation biology not just "mice don't like the smell."

Mineral Fill—Not Corn Cob

Every major competitor pouch uses corn cob fill. Corn cob is food. Mice eat it. Fugelyn's natural mineral fill is something mice have zero biological interest in they cannot eat it, shred it, or nest in it.

Gentle For Your Home

100% plant-derived essential oil formula. Safe to place anywhere your family lives  kitchens, basements, children's closets, food storage areas — with no chemical residue and no rodenticide.

90-Day Continuous Release

Mineral substrate binds to the oils and releases them at a controlled rate across a full 90-day window. Not a strong smell for four days followed by nothing. Ninety days of active protection.

No Maintenance Required

No traps to reset. No bodies to find. No poison to monitor. Place the pouches. Replace every 90 days. Everything in between takes care of itself.

why mice find your home and how to make them leave it

Most rodent repellents address one thing: scent. They assume that if a space smells like peppermint, mice will avoid it.
 

The biology is more complicated than that.
 

Mice navigate by a network of chemical signals — pheromone trails left by every mouse that has passed through before, food odors that broadcast the location of a meal from thirty feet away, and a hardwired sensory alarm system in their trigeminal nerve that fires on contact with specific compounds and commands immediate retreat.
 

A single-scent peppermint spray addresses one of these systems for approximately 48 hours. Then the volatile oil evaporates. The trail remains. The food odors remain. The mice come back.

 

Fugelyn's four-oil mineral-carrier formula addresses all three systems simultaneously — and continuously, for ninety days. Not as a scent mice dislike. As a neurological and navigational barrier they cannot override, route around, or habituate to.

Ingredients

real ingredients. real mechanism. results results

Each Fugelyn pouch contains a carefully calibrated blend of four essential oil compounds in a natural mineral carrier substrate. 

Every ingredient is selected for a specific biological reason — not because it smells natural, but because it targets a specific aspect of rodent sensory biology, navigation behavior, or nesting instinct.

No corn cob. No plant cellulose. No fill material that mice eat.
 

Just four compounds that mice cannot tolerate, in a carrier they have no biological interest in, releasing continuously for ninety days.

 

🌿 PEPPERMINT OIL 40% Concentration

Activates the trigeminal nerve the sensory nerve that processes chemical stimuli in rodents and fires the hardwired survival threat response. The mouse's nervous system does not decide to leave. It is commanded to. 

This response cannot be overridden by learned behavior the way physical trap avoidance can be learned.

The biological alarm that cannot be silenced.

🌿 CINNAMON OIL.    5% Concentration

Mice navigate by chemical trails — pheromone signals embedded in their urine that mark safe routes, food locations, and territory. Cinnamon oil disrupts this navigation system at the source. Mice cannot find their way in. 

They cannot communicate safe routes to other mice. The invisible map that keeps bringing them back is erased.


The compound that removes the map, not just the mouse.

🌿 CEDARWOOD OIL 4% Concentration

Peppermint LBlocks nesting behavior at the biological level the instinct that drives a mouse to establish territory in a location and call other mice toward it. 

A mouse that cannot nest cannot claim the space. Used in natural pest management for centuries, not because of tradition, but because the mechanism is real and the results are documented.
 

Stops the settlement before it starts.eaf

here’s how it works

Fugelyn is a natural, four-compound formula designed to make your home, vehicle, or storage area permanently uninhabitable for rodents — not by killing them, but by dismantling the three biological systems they depend on to find, navigate, and settle in your space. Instead of treating the symptom, it addresses the cause. Here is the exact sequence of what happens.

 

1

We start by triggering the alarm they cannot ignore

Your home currently contains food odors, warmth, and pheromone trails left by previous mice all of which are actively broadcasting an invitation. 

When you place a Fugelyn pouch, peppermint oil at 40% concentration immediately activates the trigeminal nerve in any rodent within range. 

This is not a scent mice find unpleasant. This is a hardwired neurological alarm that fires an immediate predator-threat response. The mouse's nervous system does not decide to leave. It is commanded to.

2

We erase the invisible map they follow to get back in

Most people who have removed mice discover usually within two to three weeks that more mice return to the exact same locations. This is not coincidence. 

Mice navigate by pheromone trails chemical signals embedded in their urine that mark safe routes and broadcast food locations to every other mouse within range. 

Removing the mouse does not remove the trail. Fugelyn's cinnamon oil disrupts this navigation system at the molecular level. The trail dissolves. The map goes dark. New mice entering the perimeter cannot find their way in.

3

We absorb the food odors that were calling them toward you

Rodents can detect food odors from thirty feet away. Your pantry, your kitchen, your grain storage, your pet food all of it is broadcasting a signal through your walls and floors that mice follow with precision. 

Fugelyn's mineral carrier substrate absorbs these ambient odors at the source, reducing the strength of the signal that draws mice toward your space in the first place. Not just a barrier. A signal reduction. Both ends of the problem addressed simultaneously.

4

We block nesting before it can establish

A mouse that enters a space is not just looking for food. It is evaluating the space as a potential territory whether it is safe to nest, breed, and recruit other mice. 

Cedarwood oil at 4% concentration blocks this nesting instinct at the biological level. A mouse that cannot nest cannot claim territory. A mouse that cannot claim territory does not stay. And a mouse that does not stay does not leave a pheromone recruitment signal calling others to follow.

5

Your space stays protected for 90 full days without any action from you

Unlike peppermint spray which evaporates in 48 hours and unlike corn-cob-filled competitor pouches which mice eat and dismantle Fugelyn's mineral carrier binds to all four oil compounds and releases them at a controlled, continuous rate for a full 90-day window. 

No reapplication. No maintenance. No checking. No resetting. The protection is active from the moment you place the pouch to the moment you replace it ninety days later. Set a calendar reminder. That is the entire maintenance schedule.

Worked faster than I expected

I started taking Fugelyn mainly for the bloating and honestly I didn't expect much at first because I'd tried similar products before with little to no results. By after a couple of weeks, I noticed my stomach felt noticeably lighter after meals and I wasn't getting that uncomfortable fullness as often. What surprised me most was how consistent it was — not just once or twice, but regularly throughout the day. I also started eating foods that I'd been avoiding because they'd make me feel sick, and now I can go through my whole routine without really worrying about it. It made eating feel a lot less stressful and more normal again.

frequently asked questions

What is Fugelyn? 

Fugelyn is a natural rodent repellent pouch containing a four-compound essential oil formula in a natural mineral fill substrate — specifically designed to address the neurological, navigational, and behavioral systems mice use to find, enter, and settle in your home.

 It is not a trap, not a poison, and not a conventional peppermint spray. It is the only natural repellent pouch on the market using mineral fill rather than corn cob — which means it cannot become bait.

How is Fugelyn different from other peppermint pouches? 

  1. Natural Mineral Fill vs. Corn Cob Fill
    Most pouches use corn cob fill, which mice can eat, shred, and use for nesting. Fugelyn uses a natural mineral substrate that rodents have no interest in, helping the pouch remain effective and intact throughout its lifespan.
     
  2. Multi-Compound Formula vs. Single Scent
    Competitors typically rely on a single peppermint scent, which mice can gradually get used to. Fugelyn combines peppermint, cinnamon, cedarwood, and a proprietary slow-release complex, creating multiple sensory disruptions that are significantly harder for rodents to adapt to.
     
  3. Controlled 90-Day Release vs. Rapid Burnout
    Traditional fillers tend to release oils quickly, causing effectiveness to fade fast. Fugelyn’s mineral substrate delivers a controlled, steady release of active compounds, maintaining consistent protection for up to 90 days.

How do I use Fugelyn?

Place one pouch per zone , under the kitchen sink, in each basement corner, in garage corners at floor level, in engine bays, in storage compartments. 

Place every 8–10 feet along known entry paths for complete perimeter coverage. Replace every 90 days. No maintenance between placements. For specific placement recommendations by property type, see our placement guide or contact our team.

When will I feel results?

Most customers report the first noticeable change within 72 hours to one week — no new droppings, spaces that previously had evidence going quiet. Full perimeter establishment typically completes within two weeks. 

The barrier does not require mice to physically encounter the pouch — the scent projects outward up to 65 square feet per pouch, which means the protection begins before any mouse reaches the placement location

Is Fugelyn safe for daily home use? 

Yes. The formula is 100% plant-derived — peppermint oil, cinnamon oil, cedarwood oil in a natural mineral carrier. No rodenticide. No neurotoxin. No synthetic compound of any kind. Safe to place in kitchens, children's bedrooms, food storage areas, spaces where pets sleep, and barn environments adjacent to livestock. 

If you have specific concerns about a particular medical condition or sensitive animal, we recommend consulting your veterinarian or physician — but the formula contains no components known to present risk to humans, companion animals, or livestock at normal placement distances.

Can I use Fugelyn alongside other pest control methods? ⊕

 

Yes. Fugelyn works exceptionally well in combination with physical exclusion methods — sealing entry points with steel wool or copper mesh, caulking gaps in foundations, weatherstripping door bottoms. The pouch provides the chemical barrier.

Physical exclusion provides the structural barrier. Both together address the problem from two directions simultaneously. We do not recommend combining Fugelyn with poison bait stations, as poison introduces the dead-rodent contamination risk that Fugelyn is specifically designed to eliminate.
