roof rat



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.

Rat Control Article:



hi there,

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.


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 noticed some large droppings on my barbecue grill a few weeks ago. I didn’t know what left them but I cleaned the grill out and was hesitatant to even use it. Then I found them again!! Whatever it is seems to like something up in the grill and is grossing me out thinking what they are doing on the grill. Do I need to throw it away and what would crawl up into my grill looking for food?

The droppings you are finding are most likely being left by a roof rat. As explained in our ROOF RAT CONTROL article, they are resourceful and will eat almost anything a human would eat. Additionally, the odor from any grill will surely lure roof rats active in the area to at least investigate what it is that smells so good. Roof rats commonly feed on nut trees and bird feeders and if any are close by are it highly likely they are in the vicinity. This means it will only be a matter of time before a rat or two made it’s way to your grill and it sounds like this has happened already.

At this time I suggest you do a good inspection of the area to see where there might be a localized rodent population that’s active. If this is on your property, I suggest you diminish the activity by using a LIVE TRAP. Failure to do so will almost certainly lead to more activity on the grill and ultimately activity in the home.

As for the grill, I would refrain from using it till the problem is resolved. You could spend some more time cleaning it but I’m afraid until you remove the local rodent activity, they’ll just come back over and over thus contaminating the grill every time they walk over it. Rats carry a lot of disease and when they move on or around objects like grills they deficate and urinate to leave scent trails. So unless you remove them for good, the grill will just get contaminated over and over since the smell of food it releases will cause the rats to keep coming back. When you are sure the problem has been resolved, a good cleaning with the NNZ will remove the scent trails which in turn will make it a lot less likely that any rodents will find it so easily in the future. Of course you can throw it away but remember, if you don’t keep the new one clean and free of odor, it too will attract rodent activity at some point.


hi, i just recently received a bunch of powder and various liquids from you all. i have thus far only used the aerosol cans for the removal of our aromatic friends the stink bug. i was telling my neighbor how wonderful the spray was working when he motioned me over and said, think they have anything for this?
something either mouse, rat or squirrel keeps eating the wiring harnesses on his truck and now his flat bed trailer. his work van and his wife’s car, because of being driven daily, have not had this happen to date but who knows. I’m right next door have and several items that sit a good bit but haven’t had an issue. that’s why i am doing the correspondence; he didn’t want whatever is doing this to read his e-mail.

There are several animals that could be doing this. The most common is the roof rat. They need to chew on things to grind their teeth as explained in our ROOF RAT CONTROL article. Radiator hoses, electric wiring and most any thin pipe or tube under a car hood has proven to be a likely target in our experience.

There are a few things that can be done to stop the problem. The simplest is to set out a LIVE TRAP up under the vehicles. Foraging rodents will find it, get caught and can then be relocated away from the property. Use our LOGANBERRY PASTE as bait and along with either bird seed or dog food, you’ll quickly catch the culprit.

ULTRA SOUND is another good option. Set out the TRANSONIC every night and it will definitely keep any animal away. Use a timer to have it operate only during the night and you can have it be essentially automatic.

ROPEL or 4-THE-BIRDS LIQUID rubbed or sprayed on the wiring will also stop them. But these treatments aren’t permanent and will have to be reapplied as needed.


Can Ropel be sprayed on fan belts in cars?  Am having problems with rodents in car engine.

Ropel is a bad tasting agent that can be sprayed on many surfaces with the hopes that target animals will find the taste unpleasant enough to stop their chewing. It’s good to use on fan belts to stop rodents that are gnawing and doing damage. If this doesn’t stop them, try one of the Ultra Sound devices we have featured in our roof rat control article. We’ve had good results using them for this exact application.


I was looking at you roof rat trap selection and I’m trying to figure out which would be best for my situation. I’ve got several up in my attick and I don’t know if I should live trap or kill trap them. What do you suggest?

As our online roof rat article explains, using a kill trap is generally only effective when you’ve got 1-2 animals to trap. This is because rats will become trap shy when they see other rats dead in any kill trap. If you suspect there are more than two rats in the attic, use one of the rat trap live cages to insure trapped rats don’t become suspect of what you’re using. Our live traps will catch rat after rat as long as you fill the trap with seed when making the set. Trapped roof rats should be relocated or destroyed to insure they don’t come back. Once the active population is removed, you can consider sealing off the attic to further rat invasions.


I’ve been hearing noise in my attic for the past two weeks and finally went up there to see what was happening. I found lots of black droppings all over and think its from a rat. What kind of rat can climb all the way up to my attic?

Most rats are good climbers. Roof rats in particular are very good and it’s most likely this is what you’ve got since they love attics. The best thing to do right now would be to start trapping them out as explained in our roof rat control article.  Just don’t start cleaning the area until you’ve got them removed and know for sure there isn’t any still up there! This way you’ll be able to keep them where they’ve been and in the end, be able to get control that much faster. If you disturb the area, you might end up moving them to some other location in the home that won’t be so easy to access. I suggest you review our online article for more details…
