Rats in your insulation? The $1,000 Rodent Reward.
No insulation is fully rat-proof. But rodents nest in soft fibreglass batts, not in our dense, borate-treated cellulose. We’re so confident we’ll pay the home owner $1,000 if a rodent nest is ever found built in a roof we’ve pumped.
Rats and mice in the roof is one of the first things people ask me about, and they’ve usually already pulled a foul, shredded nest out of their old batts. Here’s what actually happens — not a flat “rat-proof” promise no one can keep, but what rodents actually do and don’t do once cellulose is in there, and why we back it with a standing $1,000 reward.

The plain bit first
Nothing is fully rat-proof. It’s about what they do once they’re in.
There is no such thing as fully rat-proof insulation, whatever some mobs will tell you. A determined rat can get into almost any roof cavity through a gap in the eaves, a service penetration or a lifted sheet of roofing, and no product up in your ceiling changes that. Anyone who tells you their insulation is “rat-proof” is having you on. So the question that actually matters isn’t “can a rat get in?”. It’s “what does a rat do once it’s in there?”
That’s where the product really matters. Soft batts give a rodent everything it wants: loose material it can lift, tunnel under and shred into a warm, hidden nest. Pumped cellulose gives it almost nothing. It’s a dense, packed blanket with no soft lift to it, and it’s treated with borate, so the insects rats feed on can’t survive in it. So instead of selling you a slogan, I’ll tell you what I see in real roofs every week, and then we back our opinion with money.
What I pull out of batt roofs
Rats love a soft batt. They get nothing out of dense cellulose.
A fibreglass or polyester batt sits loose between the joists, so a mouse can push it up, burrow underneath and tear it into nesting fluff, and once a colony moves in, you get matted nests, chewed material, and urine and droppings soaking into the ceiling sheet below. That’s the kind of mess in the photo here, and it’s what I pull out of batt-insulated roofs constantly.
Pumped cellulose is the opposite. It goes in to a specified settled density as one solid blanket, so there’s no loose layer to lift and nothing soft to tunnel into. With the borate treatment, the insects rodents feed on can’t survive in it, so there’s little reason for them to set up house. I want to be careful here: borate is not a rat poison and I’d never call it one. But the practical result, in more than 6,000 roofs I’ve pumped, is that I have never pulled a rat nest out of one.

Money where my mouth is
We back it with $1,000, paid to the home owner, not for hunting nests.
I’m confident enough about all this to put a reward behind it. A binding written warranty, not buried in fine print. Here it is.
Read the wording carefully. The plain facts are the point. I’m not claiming rats never enter a roof. They can, and I won’t pretend otherwise. What we back with $1,000 is what they don’t do once Comfort Zone® cellulose is in there: build a nest in it. The reward goes to the home owner, it’s one per home, it covers the cellulose (not poly batts), and we arrange an impartial inspection. In more than 6,000 roofs we’ve never once found a rat nest in our cellulose. If you reckon you’ve got a case, read the full Rodent Reward terms and give us a call.

If you’ve already got a problem
We won’t blow new insulation over a mess.
If your old batts are already nested in, shredded or fouled, blowing fresh insulation straight over the top just seals the smell and the muck into your ceiling. So we don’t do that. The job is done by a Comfort Zone franchise owner-operator, trained to one standard, who photographs any existing vermin damage and flags it to you before we start anything. So you can decide whether the old material should come out, and those photos are checked before you’re invoiced.
We can vacuum out contaminated insulation and start clean. Worth remembering: insulation isn’t pest control. While the roof’s open is the right time to chase up the obvious entry points a rat is using. Seal those gaps, then lay cellulose down so what you’re left with is a clean, dense blanket rather than a nesting site.
Watch it for yourself. Rats in batts, on video
I've filmed years of this. Rats nesting in batts, the damage they do, and what a clean cellulose roof looks like instead. Press play and the whole “Rats in batts” playlist runs right here on the page.

Some of these were filmed a while back. Our methods, safety standards and products have moved on since. For how we work today, see the rest of this page.
More on rats, mice and your insulation
Is any insulation actually rodent proof in Queensland?+
No insulation is fully rat-proof, and anyone who tells you otherwise is having you on; a determined rat will get into a roof cavity regardless of what's up there. What changes is whether they can make a home once they're in. Soft batts are loose enough that mice push them up and tunnel underneath, so they shred them into nesting material and foul them. Pumped cellulose is a different proposition: it goes in as a dense, packed blanket with no loose lift to it, so there's nothing soft to fluff into a cosy nest. On top of that, cellulose is treated with borate, which means the insects rats feed on can't survive in it, and after more than 6,000 roofs I've pumped, I've never pulled a rat nest out of one. That's field experience, not a lab promise. A determined rat can still find its way into a roof; what I can tell you is exactly what they do and don't do once they're in there.
Why do rats nest in batts but leave cellulose alone?+
Two reasons, and I see them in real roofs every week. First, it's physical. A fibreglass or polyester batt sits loose between the joists, so a rat or mouse can lift it, burrow under it and shred it into a warm, hidden nest. Dense-packed cellulose has no give; it's pumped to a settled density and lays as one solid blanket, so there's nothing to tunnel into. Second, it's the borate. Cellulose is treated with a borax-based mineral salt, which means the insects rats and mice feed on up there can't survive in it. No insects means no easy food, and no food means a rat has little reason to set up house. I pull matted, urine-soaked nests out of batt roofs constantly, and in thousands of cellulose roofs, I just don't find them.
What is the $1,000 Rodent Reward?+
It's a challenge, not a bounty; we're not asking anyone to go hunting in roofs. We're so confident rodents won't nest in our cellulose that we back it with a reward: if you find evidence of a rodent nest built in a roof we've pumped with Comfort Zone cellulose, contact us (head office, not your local installer) and we'll arrange an impartial inspection, fix the affected cellulose at no cost, and pay the home owner a $1,000 reward. It covers our loose-fill cellulose only, it's one reward per home, it's paid to the property owner rather than whoever found it, and it's transferable with the house. In all our years insulating we've never once seen a rat nest in our cellulose, which is exactly why we can stand behind it with a reward. The full terms are on our Rodent Reward page.
If there's already a rat problem in my roof, can you still insulate it?+
Yes. But we'll deal with what's already there first. If your old batts are nested in, shredded or fouled with rodent urine and droppings, we don't just blow new insulation over the top of a mess. That traps the smell and the muck in your ceiling. Every job is photographed to the same system, so any existing vermin damage is photographed and flagged to you before we do anything, and you can decide whether the old material should come out. We can vacuum out contaminated insulation and start clean. And while you've got the roof open is the right time to chase up any obvious entry points, insulation isn't pest control, so seal the gaps a rat is using to get in, then put cellulose down so it stays a clean, dense blanket rather than a nesting site.
