This guide is about rodent odor in walls and vents.All ArticlesQuestionsNewestOldestMost HelpfulLeast HelpfulMost AnswersFewest AnswersBest AnswersRelevanceQuestion: Flag1It recently started smelling like dead rat in my living room. We moved and cleaned everything. I think the smell is coming from inside the wall. By Adela Answer By DCA Flag0Best AnswerUnfortunately, the smell from a dead animal can take weeks and sometimes months to disappear. The problem with dead animals in a wall or somewhere in your house is that the dead tissue breaks down and the decaying tissue produces liquids that can seep into the wood in your walls and floor. Then the problem can be more difficult to remove as the smell can continue for a long time. Sometimes the odor is so strong that the wood sections of the house may need to be replaced altogether.You can request a visit from a local pest control company for an estimate about removing the dead animal.

If you wait, you may then need to replace the wood in the dead animal's location. Reply Question: FlagBy Lynne0How do I get rid of the smell of dead mice?

You can also use a medium solution of ammonia water, and wash the area.My mom uses these methods when cleaning. Reply By Elizabeth Nead Flag0Believe it or not; kitty litter is a good odor eliminator! Put kitty litter in an open container like a flower pot and set in the closet or put it in an odd sock and tie the sock shut and drape it over the clothes rod. Do this in each closet. You will notice a difference in just a couple of days or so. I am assuming you washed the baseboards and flooring well in the closets with a strong cleaner. If there is carpet on the floor, just sprinkle kitty litter on the carpet and let it set for a week then vacuum it up.

Reply Question: Flag0I have a three story home and about three weeks ago I felt something running in the main floor ceiling and now the whole house smells really bad.

I can 't stand the smell. By Sukhdeep from Burnaby BC Canada Answer By DCA Flag0You can request the service of a pest control company to check for a possible dead animal removal. If there is a dead animal in your house, the smell will continue for months or even years depending upon the type and size of the animal. Reply By DCA Flag0An addition to my first response; if the smell is from an animal trapped in your walls or ceilings, the longer you wait, the more difficult the removal and costly the repair may be. As an animal decays, liquids released from the decay process will seep into the wood and other materials of your house. This is why the smell may take a long time to dissipate. As the decaying body material seeps into the house materials, you may need to remove the wall or ceiling area and replace it to completely fix the original problem. Reply Question: Flag0How can I get rid of the smell of a dead squirrel from my attic? I think a squirrel died in my attic about 3 day ago and I can't get rid of the smell.

I have looked all over but can't find the dead animal. Theresa from Bowie Answer By Jackie Flag0I had the same problem in my office next to the attic. I left the window open a few times. After about a week the smell just disappeared. It was bad while it lasted though. Reply By Gary T Flag0I just dealt with the same problem. I went up into the attic armed with gloves, a garbage bag, and flashlight and started searching. I initially looked towards the eaves, but I soon realized that my nose was the best way to zero in on where the dead squirrel lay. When I searched away in the wrong direction, the smell noticeably dropped off in strength. I eventually located the remains of the squirrel under the insulation in a partially melted pool on the drywall of the ceiling. I picked up what I could taking some of the loose insulation with the pile. Although I pretty much got most of it, there were residual maggots crawling around which I sprayed with ant killer. I sprayed the drywall with Febreeze (sp?) and replaced the insulation.

If the smell persists for more than a couple of days, I plan to go back up and try bleach or sprinkling baking soda. Reply Flag0Try vinegar if you have to go back, or even used coffee grounds. I had a mouse die in the motor area of the refrigerator. It took a couple of weeks to find that the smell was coming from outside the cooling area-I thought some met or other juice had spilled and the inside smelled like something dies. I used a dish of vinegar and a couple of filters with used grounds and the smell inside was gone in two days. the smell behind and under the refrigerator took longer. Reply By cynthiaeashley Flag0I was desperately searching for how to handle the smell that just started this evening. Tomorrow I have a houseful of company, staying overnight for the next few days. The smell is unbearable. I just went and,filled small bowls with fresh coffee grounds and I can actually stay in the room now. The coffee did the trick INSTANTLY! I will call pest exterminator in the morning.

Reply Question: Flag0How do I get rid of mice urine odor in the ventilation?Betty Answer By Amber Flag0I would buy some stuff called Odoban it can be bought at Walmart or online they have a website. Then I would spray it where I could and I don't know what kind of ventilation you have you might need to get creative to get it all in there. Reply By LEONA LABINE Flag0Try placing some charcoal briquettes in the vent. Use the kind for the bbq(kingsford). The charcoal will absorb the odor. Reply By Kim Churchman Flag0I would consider getting a company to go through and clean out all the habitat in there, dust mountains for example, with their cameras. Then they will put deodorizer in it. Reply By lynda Flag0I'd try very hard to get to the core of the problem first, otherwise you'll be spraying forever. It could be that just one got in there as a baby and grew up? How'd it get into the ventilation system anyway? It could also be that there is a hole in the ducting or from the outside? Time to hunt for holes the size of a small quarter from the outside or a crack that wide.
