Can rodents chew through plastic or rubber in winter storage?

The reason isn't that rodents are determined. It's that their teeth are, in a fairly literal sense, tools.

Rodent incisors are rootless and grow continuously, so gnawing is obligate maintenance rather than appetite — an animal that stops wearing them down develops malocclusion and eventually starves. And the material is formidable: incisor enamel rates around 5.5 on the Mohs scale, which puts it above human enamel and above iron, thanks to an iron-rich outer layer.

Against that, a polyethylene tote is not a barrier. It's a slightly inconvenient wall with a handle. The rim, the latch tabs and the lid seam all give exactly what a rodent needs to begin: an edge. Once there's a purchase point, the rest is just time — and in an unheated garage over a New Hampshire winter, time is the one thing they have.

This is the part worth being precise about, because it's where good intentions go wrong.

An airtight or gasketed lid does something real: it reduces the food odor escaping the container. That matters, because scent is what draws a rodent to a specific box out of forty in a garage. So an airtight bin is meaningfully better than an open cardboard one.

But odor is only half the draw, and the seal does nothing at all about the other half. A rodent that finds the bin anyway — because it's exploring, because something else in the garage smelled interesting, because it lives there now — encounters the same soft plastic and the same edges. "Airtight" is a claim about air. It has never been a claim about teeth, and the packaging that says it is is selling you the wrong idea.

The honest list is short and boring, which is why nobody writes an article about it.

Metal and glass. A metal can with a tight lid, or a glass jar, is not a container a rodent can defeat by gnawing. That's the whole answer for anything edible — pet food, birdseed, grass seed, the bag of flour someone put in the garage in October.

Removing the attractant. The cheapest version of this job costs nothing: don't store food in an unheated garage or attic at all. A rodent that finds nothing worth chewing to reach mostly moves on.

Hard-sided containers for the soft stuff. Cushions, fabric, holiday decorations with fabric or paper elements — these are nesting material as much as they are your belongings. Metal or a hard-sided bin beats a soft one, and indoors beats the garage.

What doesn't hold: cardboard, paper, thin or flexible plastic, and "heavy-duty" plastic, which buys time rather than protection. That's not a product problem. It's a materials problem, and no tote is going to solve it.

It would be easy to read all of this as "nothing works," and that's not the finding. This is one of the truly high-payoff jobs on the winter list, and it's one you can do yourself in an afternoon.

The reason is timing. Winter is the peak season for rodents indoors in a northern climate — cold pushes them toward the warmest, best-fed structure available, and an attached garage full of food-scented boxes is an unusually generous version of that. What you store, and what you store it in, is one of the few variables you fully control, and you control it before anything has gone wrong.

So: do it first. Just do the version that works. Metal, glass, or out of the garage — not a better tub.
