"First year with Fugelyn — clean interior."
Tried Fresh Cab, peppermint spray, steel wool in every gap I could find. Always found something in spring. First year with Fugelyn — clean interior. That's all I needed to see.

If peppermint spray, traps, or steel wool didn't stop it last season — here's exactly why, and what actually works for unattended storage.
See Why It's Different →You already know peppermint works in theory. Mice do avoid it. The problem was never the idea — it was the delivery.
Cotton balls dry out in 48 hours. Spray fades within a week. By the time you're two weeks into storage season, the scent is gone — and mice move in through the same entry points you treated.
Fugelyn uses a mineral fill carrier that cannot evaporate or dry out. Essential oils release at a consistent concentration for 90 full days — no fading, no gaps, no window for mice to exploit.
One placement before lockup. The barrier holds the entire storage season.

Traps are reactive — that's the whole problem. They catch a mouse that has already entered. They do nothing to prevent the one behind it.
During five months of unattended storage, a full trap sits unchecked for weeks. It provides zero protection from the moment it springs until someone resets it — which is never, because no one is there.
Fugelyn works before entry — not after. Mice detect the scent as a threat signal and don't cross the threshold in the first place.
No entry. No damage. No full trap waiting for you in April.

RVs flex. They expand and contract with temperature changes. Slideout seams shift. The foam you pressed into a gap in October has a different shape by January.
Owners who seal meticulously and still find evidence of entry aren't careless. They're sealing known gaps while new ones open from seasonal movement they can't see or predict.
A scent barrier doesn't depend on zero gaps. It makes the entire space unappealing to enter — every gap, every seam, every slideout edge — because the deterrent is environmental, not structural.
New gaps don't create new vulnerabilities. The barrier covers all of them.

Mice navigate by scent. When a space smells like a threat, they don't enter. This is documented behavior — not a marketing claim.
The problem with every other scent-based solution is delivery. Sprays evaporate. Cotton balls dry out. Corn-cob fill — used in most competing pouches — gets consumed by mice, collapsing the barrier entirely.
Fugelyn's mineral fill cannot be consumed, cannot dry out, and cannot evaporate. The essential oil blend releases continuously from day one to day 90 at the same concentration.
The signal mice detect on day one is identical to the signal on day 89. The barrier doesn't degrade. It holds.

If you've been through a bad spring, you know the number. Wiring. AC unit. Insulation. The estimate that starts at $800 and climbs.
You also know your insurance didn't cover it. Rodent damage is a maintenance exclusion in virtually every standard RV policy. The bill landed on you — all at once, right before the season you'd been planning.
Fugelyn costs $0.37 a day. One placement covers the entire 90-day storage season. First order is buy one get one free.
You've already run this calculation from the wrong side. Here's what it looks like from the right one.

The dread that builds every storage season comes from uncertainty. You don't know what's in there. You did what you could — and you also know what you found last time.
Owners who placed Fugelyn before their first protected season describe April differently. Not just the absence of damage — the absence of the anticipation of it.
They locked up in October knowing the barrier would hold. The uncertainty was gone before it had time to build.
That's what actually changes. Not just the damage rate. The entire experience — from lockup to opening — for an owner who already knows what it costs when something goes wrong.

The guy two spots down from me had a nest in his insulation this spring. $1,800 repair. I had four Fugelyn pouches in mine. Nothing.
Used to reapply peppermint every month and still found droppings. One season with Fugelyn and I understand why — the carrier never fades. Clean opening this April for the first time in three years.
Set traps every year. They'd spring and the damage kept happening anyway. Switched to Fugelyn last fall. Opened clean. No traps to deal with either.
