Coffee grounds are pleasant, powerfully aromatic and absorb odor. Other options that work on that dead mouse smell are charcoal deodorizer bags, Odor Remover Bags, pet odor enzymatic sprays and, if you're willing to spend some money, air ionizer machines.
Answer: The odor will last about 10 days or perhaps a bit longer. There is no certain way that the dead mouse can be found, and there are no chemicals that will take the odor away.
Try deodorizing with baking soda, charcoal, or pet odor enzymatic sprays. You may also use a combination of deodorizing and sanitizing solutions. Create a 10/90 bleach/water mixture. Vinegar or commercial disinfectants are also good choices.
The odor of a dead mouse is a mix of sulfur dioxides, methane and other noxious gases that are produced as tissue begins to decompose. Unfortunately, this smell can be produced by any member of the rodent family (mice, rats, etc.) that may have found its way into your walls, attic or crawlspaces and died.
They may die in your walls, attics, basements, and other hidden areas. Unfortunately, the longer you neglect the dead mice, the worse the odor will get. Dead mice also attract other rodents and pests that can increase your infestation problems.
The smelly carcass is emitting a pungent odour of decay and a "bouquet" of toxic gases like foul-smelling of rotten cabbage thiols, methane, hydrogen sulphide, ammonia and pyruvic acid. Well, the smell itself can't really hurt you but your nose.
Our top recommendations are odor neutralizers like Rat Sorb Odor Eliminator or Nature's Air Odor Eliminator. If you have found and removed a dead animal carcass, you should thoroughly wash the area where you picked them up. Doing so improves hygiene conditions and allows you to remove most of the lingering smell.
Baking Soda
Household kitchen ingredients are great for removing such a foul scent. Mixing baking soda with water and placing the solution into a spray bottle that you can spray the area where the dead rodent was found is your best bet.
Vinegar: To use vinegar as a deodorizer, fill up several cups with vinegar and place them around the home. This absorbs the dead animal's foul odor and makes the area smell better.
A dead mouse should not be left to rot inside your wall, because its corpse could soon attract fleas. With an electronic borescope, you can locate the corpse's whereabouts by drilling a coin-sized hole, a few inches off the ground, into the drywall of the cavity that seems to be emitting the smell.
Opening windows to allow natural ventilation and using electric fans may help to disperse the odour. Using DIY deodorisers to try and mask the smell, or trays of baking soda and peppermint oil (if you believe this old wive's tale) can help on a small scale.
Chances are that the carcass will dehydrate in a few weeks at which point the microbes that produce the smell as they decompose flesh will perish and the smell will vanish. In the meantime an air freshener can mask the smell. If the stench is truly overpowering, an ozone generator can be rented and run overnight.
Soak some cotton balls in vinegar and place them around areas where you think rodents might be entering your home. You can also use vinegar to clean areas where rodents have been, as this will help remove their scent.
What Happens if Mice Die in Your Walls? If you have dead mice in your walls, they typically dry up in 10 days to 2 weeks. At that point, their odor dissipates. Without drilling holes in your walls, it's difficult to extricate the offending bodies and remove the source of the smell.
Make use of any odour absorbent devices. Air fresheners and deodorisers, as well as candles and essential oil diffusers, can also come in handy. Peppermint oil, for instance, can do more than just help with the dead rat smell removal. It is also a natural rat repellent.
The most effective way to eradicate the smell of a dead rodent is to remove its corpse, disinfect the areas where it nested, and air out your house with fans and deodorizers.
In most cases, people get HPS after inhaling particles from infected mouse poop. However, hantaviruses can also spread through: Bites from an infected mouse or rat.
Decaying rat and mouse matter can almost be thought of as poison since the particles and pathogens released into the air can severely affect your respiratory system.
Rodents such as rats and mice are associated with a number of health risks. In fact, rats and mice are known to spread more than 35 diseases. These diseases can be spread to humans directly through handling of live or dead rodents, contact with rodent feces, urine, or saliva, as well as rodent bites.
Other Mice
As many know, dead mice give off their own smell. Strangely enough this smell can attract other mice, especially when food is scarce. That's right- mice will eat dead mice if they need to. They are scavengers which means they will eat whatever they can possibly find, including their fallen cohorts.
Mice are not afraid of new things or bothered by the smell of humans or dead mice on traps. If you have many mice, you might have to use a multi-catch mouse trap or a glue board.
Rodents will feed on non-human foods like birdseed and dry pet food in a pinch. They have incredibly sensitive noses and can easily smell your food through walls and packaging.
Wear a mask and rubber gloves. Place the dead mouse in a sealed bag or container. Place the bag or container in an outdoor trash can. Clean up any areas where the mouse may have been with a disinfectant to reduce the risk of contamination.
