Rats will readily move into attics, basements, wall voids and any place where they find shelter and a good meal. Pet food, bird seed and vegetable gardens can all attract rats to any house. And once they find a good place to feed, it won’t be long till they move inside. If you’ve got rats in the attic, on your deck or suspect they’re…. READ MORE ON ROOF RAT CONTROL
There were rats nesting in the insulation in the underbelly of my single wide mobile home. I’ve managed to get rid of them and block the entryways.
The odor is terrible and coming in strongly through the floor registers. I simply cannot afford to have this removed and replaced. Does the odor EVER dissipate EVER?……:(
The odor will not dissipate on its own. But you can neutralize it using the right product. You see, odors from animals like urine, feces, pheromones, etc. are “alive” and cleaning compounds will not eradicate the smell. For that goal you need what we call an “enzymal” agent like NNz.
So for this problem, you’ll want to mix 8 oz of NNz per gallon of water and spray or fog the solution under the home. Use 1 gallon for every 500 sq/ft. Be sure to cover all surfaces; the NNz must contact the odor to neutralize it. We have been recommending this product for over 20 years and its worked every time so you can’t go wrong with this option.
If you have a good PUMP SPRAYER and access to all areas under the home, you should be able to do an adequate job of covering all surfaces.
But if the area is tight and hard to access, consider renting our FOGGING MACHINE. This will enable you to do the treatment with very little effort. The machine will blow the mist a good 20-30 feet so you can cover all areas by just placing the machine under the home, turning it on for a few minutes and letting it run. The rental costs $50.00 but we pay to ship it to you and include a return shipping label so there is no extra cost. And you get to keep it for 2 weeks which is plenty of time to get the area treated a few times.
If preferred, you could purchase a MINI FOGGER for a little more and after solving this problem, use it to fog the yard for mosquitoes, gnats, etc.
Lastly, if your furnace blower is located under the home, it is no doubt pulling foul air which is in turn circulating through your air ducts. To purge lingering odor in these areas, you can set a saucer or bowl of NNz concentrate just after the filter inside the unit. Nothing large; small enough yet heavy enough to be stable so it stays where you place it.
If placed in the air flow, the NNz will be “sucked” up as air is drawn in and pumped through your system during the heating or cooling of the home. This way any malodor which has found its way into the ducts will be neutralized.
You can also using either of the fogging machines above to fog into the registers for 10-20 seconds as needed. This will provide quicker results in case the odor is actually in the ducts. But its more likely coming from underneath the home so once you solve the problem at the source, the air circulating will be odor free too.

I found your webpage and not really sure which trap would be best for me. I’m looking for a Multi Live Rat Trap. I will be using it in my yard. Every summer I seem to attract the Rats with my bird feed and all my fruit and tomatoes plants. I’m against killing any living creature and would prefer to trap and release in the hills or open fields. Which trap should I consider? Thank you.
I suggest the REPEATING 5X5X30. It can hold several rats at one setting is ideal for small animals like rats, chipmunks and squirrels. This trap will last a good long time and one or two of these in the yard would prove effective.

I understand how the rat zapper works but once it kills the animal would the rodent not continue to short out the plates while it lays there dead? I have to work during the day so would not be able to immediately dump the trap as suggested..
This was very much a concern during the initial design of these units and is currently a “non issue”. The work around is simple.
Basically once the unit is grounded out, there is a built in timer which is activated. This timer will allow the a specific amount of stored current flow for 1-2 minutes and then it cuts the circuit. This insures the unit does not continue to ground out and shorten the life of the batteries needlessly.

Your video about determining what rodent is in the attic was the best ever, thank you. Sadly, I have rats as indicated by the droppings. I think I’ve found the 2″ hole they use and my question is, how many times does a rat need to leave the property to get food/water? Will there ALWAYS be droppings next to the hole under the eves? Dang, the local pest control companies don’t deal with attic problems here, so its up to me. Thanks so much.
There will most likely be droppings appearing over and over as long as rodents are using the area. As for what to do? Right now, I recommend reading through our RAT CONTROL ARTICLE where you’ll learn various control methods. In the article you’ll learn the best method to control this pest is to live trap them out. Based on the fact that you know where their entrance hole is located and you see plenty of droppings, it should be easy to catch them.
Just set out one of our LT5518RD LIVE TRAPS at this spot baited with some PECAN PASTE and you should catch them quickly. And if you have a pet or bird seed, be sure to add some to the set as this will no doubt get them to enter that much faster.
Now every time you catch one you should then remove all their droppings and reset the trap. Once you get to the point where there are no new droppings appearing and no rat in the trap for two weeks or more, you can proceed to sanitize the attic, the outside area around the entrance hole and then lastly, proceed with doing some exclusion by sealing up the hole.
To sanitize the hole, you’ll want to spray down the area with NNZ we discuss in the article. By neutralizing their scent, you’re insuring more won’t find their way inside so this is very important and needs to be done.
As for how often do they leave and forage? Usually every evening/night. But as our article explains, females return daily too. Males, on the other hand, will many times use many nest locations and only return every few days to your home so don’t expect consistent activity and then be led to think they’re gone. In fact this is why you need to wait at least 2 weeks before sealing up any holes.

What other options do you know of, to exterminate Rats that are inside of the living area of the house. All entry points from which the Rats entered the structure, from the out side have been secured. I have already caught 1 rat inside of the house one under the house using snap traps equipped with the yellow plastic bait holder, another rat was caught on a glue board inside of the house, but managed to get away. I’m using peanut butter and bacon for bait.
If you review our RAT CONTROL article, you’ll see we list several other trapping options. Other points of interest in our article actually address the results you’ve had. In fact what you’ve experienced is pretty much what our article says one should expect when using either SNAP TRAPS or GLUE TRAPS.
With Snap Traps, if you don’t set 12-24 traps, there is a good chance the local population will learn to avoid them after seeing other rats get killed. Same with Glue Traps. Since rats are strong and can escape their grip, rats will learn quickly to avoid the smell of glue once they see 1 of their kin caught.
At this point I suggest you get 2-3 LIVE TRAPS. As our article goes on to explain, rats won’t get afraid of these since they don’t kill anything. And if you place a lot of bird seed or pet food inside the trap so that rats which enter will think they’ve found a “pot of gold”, other rats will anxiously try to enter. With the single catch traps this won’t be an option but that’s okay. As soon as you remove the trapped rat and make a reset, any still in your home will eagerly enter the empty trap because they won’t learn to fear the device because it’s not hurting or killing them.
Of course, if you suspect you have a lot of rats still inside, get one of the REPEATER TRAPS since they can capture many at one time. As for bait; be sure to use what they’ve been feeding on as lure. I know it’s not been peanut butter and bacon; I’m betting it’s either pet food or bird seed. And if that’s true, use one of these as this is more of what they expect and love. Peanut butter and bacon isn’t on the normal menu for rats and when making trap sets, it’s best to offer what they can find close by or have been feeding on. When you introduce something “new”, it alarms them and many times they’ll avoid this odd food.
Lastly, the fact that you have already sealed up holes presents a whole new set of problems. First, as our article explains, you should always leave these in tact until you solve the problem and THEN seal them up. This is because rats like to go in and out of any structure. And when you know their entry points, you know where to trap. Now as soon as you seal those, you force the local population to find an alternate route. In this process they’ll no doubt find another pathway and this will be unbeknownst to you so that even after you get rid of the current problem, there will now be entry ways into your home you don’t know about. This is bad.
Hopefully there is only 1-2 rats left for you to trap and if that’s true, the amount of alternate pathways they make will be minimal. But as our article explains, rats use scent for their trails and once the population is removed, you need to clean up the inside and outside areas with some NNZ. By removing their odor and scent, you’ll greatly reduce the likelihood of new rats finding your home and coming inside. Scent can last 1-2 years with no problem and this is the main reason homes get infested over and over again with rats and mice. You must remove the smell that’s no doubt on your house if you don’t want future problems. Hope this helps!

I may have dead rats underneath the woodwork, underneath the walls in the house. What should I do and what product can I use? Will the smell go away? And is the smell of ammonia resemble dead rats ? Your help is greatly appreciated.
If you read through our RAT CONTROL ARTICLE, you’ll learn that the use of a rodenticide in the home will many times lead to an animal dying somewhere inaccessible. But the general rule is anytime you have any kind of animal active in or around your home, there will be an increased risk of something like this happening. Fortunately there are some good products that can remove the smell.
For now read our article. As you’ll learn, removing the animal is always best. But if you’re not able to find it, you’ll have to treat with the NNZ we list in the article. You can spray it out over the area where you suspect the odor is located but if it’s a wall or ceiling void, you may need to use one of the FOAMERS to get good coverage.

Does your company have a foam product that can be used to fill holes and will keep mice from chewing through it?
We do. For small jobs, the BLACK FOAM is the most common professional product used. The 16 oz can comes with it’s own hose so it’s ready for use and good for small jobs. The larger 32 oz can must be used with a FOAM GUN.
The maximum strength FOAM REPELLENT product works the same way but also has a “built in” repellent flavor making it stronger. It can only be used with a application gun like the one listed below.

We just bought a house and the attic was infested with roof rats. The pest control company has heavily baited and it has been two weeks & there seems to be no more rat activity. The problem is that he said it was the worst rat urine problem that he had ever seen! It must have been going on for several years. How do we neutralize this rat urine up in the attic that has soaked into the insulation? Or will I have to have all of my insulation removed and new insulation put in which will be a large expense that we were not counting on. Please advise us. Thanks.
There is no doubt roof rats can create a mess along with some nasty, foul and biologically unhealthy odors. Locally we have companies that specialize in insulation removal due to odor problems similar to what you’ve described. In my mind, removing the contaminated material is the only way to go. I suggest you remove as much as possible and then vacuum with an industrial shop vac to get anything loose. I also recommend using a RESPIRATOR, RUBBER GLOVES and DISPOSABLE COVERALLS to insure anyone working in this environment avoids the hazardous contaminates undoubtedly present.
I then suggest treating with the NNZ ODOR NEUTRALIZER. It does a great job of breaking down and eliminating odors and is very effective on both rodent droppings and their gland scent which undoubtedly is distributed throughout your attic space. I’d let the area sit for a few days before I reinsulated just to make sure the treatment was effective and to your satisfaction. In most cases we find people have to treat just once but in extreme situations a second spraying may be required. Based on the description you provided, that might be in order for you home.
On a side note, hiring a service company for this task will no doubt be quite expensive. I wouldn’t be surprised if it would be a couple of thousand dollars depending on where you live, the size of the attic and some other factors. Doing it yourself would be a huge cost savings but obviously it will require some hard work.

we have had an ongoing rat problem since we’ve moved in to this house (here in atlanta!) there are places in the house on the carpet where rats have left their “scent” shall we say…. and one of these being in the room where my newborn will sleep. nice. do you have an organic spray that will neutralize the scent so they won’t come back? our pest control company said that smell is so strong they come back to it…
Roof Rats will definitely create and use scent trails to navigate their way around. Their vision is limited but they have an amazing sense of smell and use it to the fullest potential as explained in our ROOF RAT CONTROL ARTICLE. In fact, it’s clearly one of the biggest reasons why homes that get rodents once have a tendency to get them again; the lingering odors and scents are clearly an attractive nuisance and should be removed for long term rat control to truly be achieved.
If you check out our RODENT EQUIPMENT page, you’ll find a section on ODOR CONTROL. In this section there are links for two products that will solve this problem. Both NNZ and N7C are organic and can safely be used in the home. These products don’t mask or “clean up” anything. Essentially they break down and decompose the odor molecules that have been left behind. This decomposition process will morph the odor into another “scent” altogether and most importantly, one that roof rats will not interpret to be their own (and not detectable by humans). Of the two, I’d recommend the NNZ. It’s the odorless version and best suited for inside applications where no smell is the desired end result.
Additionally, it would be ideal if you are able to peel back the carpet and get the treatment down under the rug as much as possible. If there is wood or cement under the carpet, there is no doubt some of the odor molecules embedded on this substrate as well. This means treating over the top of the carpet won’t be nearly as direct as we like to make the application. In the end, the more direct you administer the NNZ, the better the results you’ll enjoy (and the faster they’ll be noticeable). You may be able to achieve the same result by spraying over the carpet but there could be a impact on the carpet color since it will require a lot of water to get the NNZ down through the carpet. That means a good soaking and this process could alter or change the color of the rug. Avoid this altogether by treating under the carpet. After the initial application you can mist over the top of the carpet to ensure the carpet fibre’s aren’t harboring any scent.
For more information on the NNZ, check out the NNZ LABEL we’ve posted on line. And if you have further questions about how to do the job, please give us a call at 770-985-9392 during our normal business hours.
I found your info very useful. I’m wondering, are cats helpful in scaring away rodents that are inside a house?
Great question! No doubt lots of people believe this to be the case. But is there any scientific research or testing to confirm or dispel this widespread urban legend? Not that we’re aware of. However, we’ve done a little research on our own… And the results may surprise you!
First, one would think cats to be natural “ratters”. It’s common for cats to kill, retrieve and drag around small animals like mice, birds, lizards, rats, chipmunks and squirrels. But do all cats display this behavior? That would be a definite no. And what % of cats do? Anyone’s guess. I think most don’t have the chance to show they’re capable of doing it and even the few that do aren’t nearly as effective as their owners would like to think.
Which leads me to my next point. Most people who have pets like a dog or cat that routinely retrieve small animals are quick to point out their animal does this all the time. In these situations it becomes clear their pet is sometimes finding animals in their domain. In other words, for house cats that don’t go outside, the rodents are clearly coming inside. And many times the cats are able to get their “prizes” several times a week. This leads us to believe the rodents are “co existing” with the predatory cat or dog. Seemingly they don’t care! And for pets that venture off their land to seek their prey; we have found many of these pet owners to have an ongoing active rodent problem! In other words, we have customers that come to us confused because their pet hunts small animals yet they know they have a rodent infestation and can’t understand how this could be.
All this mixed data leads us to believe that cats and dogs can and will hunt small animals. But once they became domesticated, this hunting behavior became something they didn’t need to use to live or survive. That means it will be “fleeting” at best and not done to the level needed to provide true rodent control or pest elimination. And since we’ve seen case after case of rodents co existing with both dogs and cats that either don’t care or do kill some of the unwanted small animals found in their domain, in neither case do the rats or mice active seem to care. In other words, the pet doesn’t seem to deter or frighten the rodent away. Which explains why more than 50% of our customers with rodent problems own pets! One would think the two might be directly related but I’m pretty sure the relationship is more of a related “interest”. And this interest seems to be food.
No doubt pet food (in all forms) is more of a rodent attractor than the pets are a rodent repeller. This we are 100% sure and base it upon 30+ years of data. As explained in our ROOF RAT CONTROL ARTICLE, pet food is very nutritious and will attract rodents from far away. So to answer your question, I’m 100% there are some cats that can “scare away rodents that are inside a house”. But do all cats scare rodents and are all cats even interested? No way. And are all rodents afraid of cats or other pets? Nope. In fact, it seems as though they are able to gauge whether they should be frightened or not and when they detect a pet that might pose a hazard to them, the rodent will many times avoid the pet but still use the structure to some degree for either food or shelter. So even “rodent hunting pets” – or at least pets that show this trait strong enough to alert rodents to the fact they could be in trouble for hanging around – aren’t able to keep rats or mice away for sure. In the end, this glaring fact means that if wish to keep your property and house rodent free, you’d best follow the guidelines and practices outlined in our rodent control article. Hope this answers your question!!
Firefighters say rodents may be the reason a fire broke out Thursday morning in Chico. The fire was called in by a neighbor around 7:45 AM after they saw smoke and flames coming from the upper level of the home. The resident told firefighters he heard a scurrying noise in the attic a few hours earlier, around 1:30 in the morning, and then the power went out. Roof rats, squirrels and mice will commonly chew power lines so it wouldn’t be a surprise if they indirectly caused a short.
The homeowner apparently didn’t realize the danger and just reset the circuit breaker. About 6 hours later the fire broke out. You can read the full the story here:
In fact, rodents regularly chew on pipes, wires and just about anything attempting to grind down their teeth. As explained in our ROOF RAT CONTROL article, they do this instinctively. This is just one more reason why roof rats should not be tolerated in or around the home. Be sure to trap out local populations if you find them in or on your house using one of the methods detailed in our article.
I am not able to have rodent repellent shipped out here to California so I am in the process of receiving granule repellent for cats and dogs. Is this gonna work on rats? And can Ropel be sprayed on fan belts in cars? Am having problems with rodents in car engine.
Thank You, T.T.
ROPEL can be used on anything. The only issue we’ve seen is some discoloration when treating certain fabrics. I don’t think this will be of any concern when treating under the hood of a car and over the years we’ve had people use it successfully to stop rats, mice and squirrels from chewing on their vehicles.
Another option is to set out a LIVE TRAP under the vehicle. Small animals are easy to catch and once trapped, you can relocate them far away so they can’t access your vehicle anymore.
Lastly, another great option is the TRANSONIC PRO ULTRA SOUND. It’s got variable settings and works well on both rats and mice. Install one set up with a timer as described in the following video and I’m sure you’ll be able to keep them away.

I have a dead rat in the refrigerator. We have looked under and behind and removed tile under appliance but cannot locate it. We think it is probably in the motor housing or up inside some insulation. We can’t lay the refrigerator down without causing damage due to it’s design and size. This is a new appliance. Do you have any suggestions on how to control the terrible odor?
Rats and mice will many times seek out tight places to hide. Motor housings and the surrounding environment are prime locations and as the cold of winter sets in, rodents will come inside looking for these exact locations. They generally offer warmth and moisture as well as a secure location to keep them protected from predators and the harsh season outside. These same locations also have a lot of hazards including electrical and mechanical parts which can end a small rodents life abruptly.
When rats or mice die in an appliance such as a refrigerator, a bad odor will usually alert the homeowner of it’s presence. At that point the dead rodent should be found and removed. If it cannot be found and removed, treating the motor and other components of the appliance can be done with some NNZ ODOR NEUTRALIZER. This product can be sprayed lightly over the housing, compartment and surrounding area. With any luck it will trickle down into key voids or spaces where the dead animal is nestled. Expect to repeat treatments daily till the carcass is decomposed.

I see the line of rodent zappers you carry but I don’t think I need one this big. After reading your article I’m pretty sure I have mice and not rats in my kitchen. Do you have a scaled down smaller version for mice?
The RAT ZAPPER line will work fine on mice. If you are unsure of just what rodent is active in your home, we always suggest going with the larger size since it will usually work on any animal that can enter. If you are sure mice are active and have a limited area to deploy the device, go with the MOUSE ZAPPER. It will kill any mouse or shrew instantly and has an entrance that makes it pretty much impossible for non target animals to get inside. The following spotlight video goes over all the details you’ll need to know to set one up.
