Hi guys, Craig the Odor Dude here, welcome to the rat page 🙂
On this page I cover how to remove rat urine odor from an attic or ceiling space, from the subfloor and timber framing plus how to remove dead rat odor if a rat got stuck inside a wall or cavity and has died.
You can also use the same principles for mouse urine odor removal.
"HOW DO I STOP RATS COMING INTO MY HOME?"
Before we continue with the rat urine removal content I want to cover off a question we get asked on a regular basis.
"HOW DO I STOP RATS COMING INTO MY HOME?"
There are many theories out there, most don't work.
Here is one that does work!
The secret is to blast them with Ultrasonic + Electromagnetic waves.
This fine piece of engineering shown below uses Ultrasonic + Electromagnetic waves to get rid of rodents and other unwanted creatures.
Just plug it in and forget about rats.
Designed in Chicago by leading engineers it will send the rats to the hills, and the cockroaches to the neighbours. On a serious note it does get rave reviews and we recommend it. AAAA+++
800 positive reviews can't be wrong!
How to remove rat urine odor from ceilings, garages, attics and other exposed areas.
This is the most effective way. I use a formulation that I make myself. Its very easy to make, and the components are readily available. If you can make a cup of coffee you can make this simple formula.
It is highly effective on rat urine and if needed you can increase the strength for bad cases.
My formulation works very well on rat urine as well as other pet urine contaminations.
Along the way I have worked on perfecting this DIY formula and my methods so I can help home owners like you remove rat urine odor themselves easily and effectively.
You can make it at home yourself very easily
I suggest click here to buy the formulation then return here for instructions on how to use it.
I have also incorporated some new ingredients into my formulation that helps you find the main contamination areas by the product foaming white on contact.

Rat Urine Removal
“I have done it, The smell has gone. The problem was as you suggested, that I did not know where the main areas of contamination were so I was treating the wrong area. I sprayed the formula around and looked for the foaming as you suggested. (there was a lot of foam by the way) I then applied a heavy dose and left it over night. I repeated that the next day and one day later the odor now is 5% of what is was. It has made such a difference to us and I can not thank you enough. It know it will keep working over the coming days (love how it does this) which gives us peace of mind. Thx!!!
Here are the step by step instructions on how to remove rat urine odor from an attic and ceiling
Step One. Mix up approximately 2 quarts of my formulation. (That will take you about 2 minutes and all you need is a bucket and some gloves. Its costs about 50 cents a gallon to make and is highly effective on rat urine.
Step Two. Spray some of the formula on the area where you think the urine is located. Look for foaming as shown below. This is the best way to locate the areas you need to treat.
Step Three. Apply the product.
Investigate the sprayed areas and see how much foaming is present. This will indicate the levels of the contamination's i.e minor equals light foaming and serious is indicated by heavy foaming.
Rats don't pee large quantities but rodent urine is renown for being strong and pungent. This is the same when you are dealing with mouse urine odor removal.
The ability to remove the rat urine smell relates to what the ceiling or attic space is made from. Urine will penetrate to different levels depending on what the substrates are.
Typically the framing is raw wood which absorbs rat urine quite easily and if the rats have been in the ceiling space for a long period of time then you will need 2-3 treatments to penetrate in as deep as the urine is.
Drywall will need several applications (look for reduction in foaming each application) if the contamination is old and very severe.
Replace insulation if it is contaminated.
Use Formula Two and give it several applications
The video below gives a step by step guide on what treatments to use.
If the ceiling material is made out of fiberboard, plaster board or gib board or similar then that is also very absorbent and will need several applications of Formula Two.
No need to treat areas that are not foaming up. In a lot of cases we had to treat the timber 3-4 times with Formula two then once dry, seal it with a very resilient sealer to lock in the residues
This was when Ken owned the business before I bought it.
Please be careful if the rats have chewed through any cables. call an electrician and take extreme care. Fluids and electricity do not mix!!
How to remove Dead Rat Odor From within a Drywall.
Click the image below for more information
More often than not we get inquiries where people have a dead rat stuck inside a wall. If the rat is behind the Drywall or Plasterboard then the best option is to cut a whole and try to remove the carcass. Not easy if you don't know where the rat is but if you do know then the best bet is follow instructions below.
Step No One for removing dead rats from within your walls:
Cut a hole in the wall where you believe the rat is (You may need to cut a few holes but they are easy to fix)
Step No Two: Remove the carcass of the rat and safely dispose off. Make sure you wear gloves and a breathing mask
Step No 3: Treat The Area with Formula Two (My secret Odor Removal Product that you can make using 4 simple ingredients)
Spray the area where the rat was located and look for white foaming. If you get white foaming then hammer that spot with the formula several times, then allow to dry. Check for smell after that and repeat if necessary. A good way to test it is to apply formula two and watch for foaming. let it settle for 5 minutes then apply more chemical. If you get the same amount of foaming it means it is a severe contamination and will either require multiple applications over a period of a day or two.
Step No 4: Once smell is treated and removed start to repair the wall
Tools you will need
* Utility Knife
* Drywall Joint Tape
* Drywall Screws
* Taping Knives 14"" and 3 "
* An electric drill
* 1" x 1" dressed piece of wood to use as a backer
* Sanding disc and 220 grit sandpaper
* Quickset Joint Compound
* A square and a measuring tape
* A Pencil
- Cut out a piece of drywall the same size as the piece you cut out
- Repair Wall as shown in Video below
If you have dead rats remaining in the area then this product is perfect for the odor. (For dead Rat Odor )
Using Ozone Treatment to remove Rat Urine Odor.

Ozone is very effective for odor removal and can boost the whole process plus sterilize your home and serve many hundreds of useful purposes around the home
Enerzen Commercial Ozone Generator Review
Pros: The Enerzen Ozone generator is incredible value and has high output of Ozone enough to do the shock treatment needed to remove and minimize rat urine odor in hard to get to places.
* Although they state 5 grams of Ozone per hour on the specification sheet I believe it outputs more than that and comes with an adjustment knob for lowering the ozone output if it is too strong.
* The method for producing Ozone is via Corona discharge and this is our preferred method for generating Ozone gas as it lasts the longest and requires little or no servicing. (we have tried light bulb ozone machines in the past with limited results)
* Comes with a timer which can be very useful to stop ozone levels building up to much. We have found also that doing Ozone shock treatments is more effective than prolonged. Shock treatments are numerous blasts with a machine rather than leaving it running continuously.
As a commercial operator most machines do not have a filter on the inlet which means debris will get inside the machine and require cleaning at regular intervals if machine is used alot. we use a simple vacuum cleaner to extract the lint etc.
Buy It ! Its great for rat urine.

What is ozone ?
Ozone is a colorless gas comprised of three atoms of oxygen (O3). It is one of the greatest disinfectants worldwide with 3000 times the germ killing power of Chlorine OG-5000 has variable ozone output permits option of adjustable ozone level from 0-5000mg/ hr. When ozone can be found in contact with mold and mildew, pollen, odors, or other airborne germs, one of those atoms integrates with the pollutants rendering them non-active by oxidation, leaving behind pure clean oxygen. This high output ozone generator (as much as 5000 mg/hr) can assist: reduce/kill levels of airborne bacteria reduce/kill black mold and mildew reduce/kill fungi reduce/kill mold spores reduce/kill smells and viruses.
