If you have heard scratching overhead or found droppings, this is the fastest way to deal with it. We remove the droppings from accessible attic surfaces, sanitize what was contaminated, and photograph the work — for $64.
This is a targeted attic cleaning visit, not a full attic restoration — and we would rather you know exactly where the line is before you book than after we arrive.
Visible rodent droppings lifted off the top of insulation, plywood and other exposed surfaces using a 5-HP vacuum, handled with PPE and containment so nothing gets stirred into the air you breathe downstairs.
The areas where we found contamination are treated with EPA-registered disinfectants under a CDC-informed protocol — applied at the source, not sprayed around as a deodoriser.
Where openings are reachable on the day, we close them with 1/8-inch steel mesh or steel wool, then seal over the steel. Rodents chew through foam and caulk; they do not chew through steel.
The honest limit of a $64 visit: this covers light to moderate droppings on accessible surfaces. It is not a full attic cleanout, not a full rodent exclusion, and not insulation replacement. And if your attic turns out to need more than this, you do not pay the $64 at all — you get a free written estimate for the work that would actually fix it, and you decide from there.
Warm air rises. As ENERGY STAR explains, it leaves your living space through gaps around light fixtures, bath fans, plumbing stacks and the attic hatch, and it pulls replacement air in behind it. That means the air sitting in your attic is connected to the air in your bedrooms — which is why an attic full of droppings and nesting debris is not just an attic problem.
The CDC publishes guidance on cleaning up after rodents for exactly this reason. Rats, mice and squirrels get into attics looking for somewhere warm and dry. What they leave behind is droppings, urine, shed hair and nesting material worked down into the insulation. Left alone, that is what you are circulating.
Attic cleaning is the first step because it is the one that stops the contamination getting worse while you decide what else the attic needs.
Removing droppings from an attic that still has open entry points buys you a few weeks. The animals that made the mess use the same routes to come back and make it again. That is why every opening we close, on this visit or any other, is backed with 1/8-inch steel mesh or steel wool first.
Foam, caulk and stucco patch are legitimate materials — they close a gap, block airflow and finish a repair neatly. What they cannot do is stop teeth. A rodent chews straight through any of them. So the steel goes in first and the sealant goes over it. We never rely on foam alone.
Openings we can safely reach on the day get closed with steel and sealed. You get photographs of each one.
A complete perimeter inspection and closure of every entry point, including the ones needing ladders, roof access or dismantling. Different job, different scope.
Into the attic with a light and a camera to see what is actually up there — how much contamination, where it is, and whether the $64 scope covers it. If it does not, you hear that before any work starts.
The hatch area and the path to it get covered. Attic work is dusty; none of it should end up on your floors.
Visible droppings lifted from accessible surfaces with PPE and containment, using a 5-HP vacuum, and bagged on site. That is the right tool for surface cleanup — the 35-HP extraction rig is for pulling out whole insulation, which is a different service.
EPA-registered disinfectants applied to the areas where contamination was found, under a CDC-informed protocol.
Accessible entry points closed with 1/8-inch steel mesh or steel wool, then sealed over the steel. Photographed before and after.

After enough attic cleaning visits you stop being surprised. The same handful of things turn up again and again, and each one tells us something different about how long the problem has been running and what else the attic is going to need.
Droppings on top of the insulation are the obvious sign, but the more telling one is staining underneath them. Fresh activity sits on the surface. Older activity has worked down into the material, and urine has usually followed it. Surface droppings can be lifted off; material that has been saturated cannot be cleaned back to sound, which is the point at which we start talking about removal instead of cleaning.
Rodents shred insulation, cardboard, stored fabric and anything else soft into nests, usually tucked against a warm surface like a chimney chase or a duct run. Finding a nest tells us the attic was not just a route through, it was somewhere they settled — which usually means there is more contamination than the surface suggests.
Flattened channels through the insulation are travel routes, and they lead somewhere. Following them usually takes us straight to an entry point we would not have found otherwise, which is exactly why we look before we start cleaning.
Rodents chew to keep their teeth in check, and wiring insulation and flexible duct are both soft targets. When we find it, you get told and photographed even though repairing it is not part of an attic cleaning visit. You should know it is there.
Insulation that has been walked over, tunnelled through or pulled about has lost the loft that made it work. It looks like insulation and performs like a blanket. Cleaning the surface does not restore that, and we will tell you plainly when the material underneath has stopped doing its job.
For a lot of homes, the $64 attic cleaning is the whole job. Light contamination on accessible surfaces gets removed, the affected areas get sanitized, reachable openings get sealed in steel, and that is the end of it.
For others it is the first step, and it is worth knowing the order the rest of the work has to happen in — because doing it out of sequence is how people end up paying twice.
If rodents can still get in, new insulation is nesting material you paid for. Every entry point has to be found and backed with 1/8-inch steel mesh or steel wool first. Only then does replacing insulation make sense.
Air sealing the ceiling plane means working on the surface the insulation sits on. If contaminated material is still in the way, it has to come out first. That is insulation removal, not attic cleaning, and it runs on a 35-HP extraction rig under containment — bagged on site rather than shaken loose into the air.
Sealing the gaps around light fixtures, bath fans, plumbing stacks and the attic hatch is what stops your conditioned air escaping into the attic. Blow fiberglass in first and those gaps are buried and unreachable. We seal, then insulate to a measured depth, and photograph the ruler in the material so the depth is not something you have to take on trust.
You are not committed to any of that by booking the cleaning. The $64 visit stands on its own. If the attic needs more, you get photographs and a written scope showing what and why — and the quote stays valid while you think it over, compare, and decide.
Rodent droppings and urine are a genuine reason to deal with a contaminated attic, and public health agencies treat cleanup as work that needs care rather than a broom and an open window. That is why our technicians use PPE and containment, and why we do not sweep or blow contaminated material around.
What we will not do is quote you frightening statistics to close a sale. The honest position is this: droppings and nesting debris in a space that shares air with your living rooms is not something to leave indefinitely, the risk depends on how much there is and how long it has been there, and cleaning it up properly costs a lot less than most people expect. That is the entire argument.
Attics are not sealed off from the house. Air moves between the two through every gap in the ceiling plane, and warm air rising out of your living space pulls attic air along behind it. Anything sitting in the insulation is part of that exchange. It is the reason people often notice the smell or their allergies before they ever see a dropping.
If you are considering handling it yourself, the main things that matter are not disturbing the material dry, wearing proper respiratory protection rather than a dust mask, and bagging waste rather than sweeping it. Most homeowners decide the attic is not where they want to test that — which is fair, and is why the service exists.
It is a good fit if you are dealing with light to moderate contamination on accessible surfaces:
When we will tell you this is not the right service: heavy infestation, insulation that has been nested in throughout, standing contamination across the whole attic floor, or damage to the framing. In those cases the $64 visit does not solve your problem — so we do not charge it. You get a free estimate for the job that would, and you are under no obligation to book it.
Rodent activity in Southern California is not really seasonal the way it is elsewhere. Our winters are mild enough that attics stay attractive year-round, and the first cool nights of autumn tend to push activity up rather than shut it down. So the honest answer on timing is that it depends on what you are seeing, not what month it is.
The one situation where waiting reliably costs more is active rodents. Contamination compounds — a job that would have been a $64 attic cleaning in spring becomes a full cleanout and insulation replacement by the following year. If you are hearing them now, that is the moment the cheap version of this job is still available to you.
Nothing much is required of you. Clear a path to the attic access if it is inside a closet, move anything precious out from directly beneath the hatch, and keep pets in another room while the hatch is open. If you know where you have heard the noises, tell us — it genuinely helps us find the entry points faster.
A straightforward attic cleaning visit on an accessible attic is usually a couple of hours, and you have the photographs the same day. Attics with restricted access, low clearance or heavy contamination take longer, and if that is what we find we tell you before we start rather than surprising you with it afterwards.
Attic cleaning is one step. If the attic needs more than a clean, these are the services that handle the rest — and the pages explaining what each one actually involves.
