How to Get Rid of Dead Mouse Smell


Once you have dealt with mice in your house by poisoning them, you would be dealing with a dreadful, sickening smell that overtakes the house. The first step involves identifying where the smell is coming from. You know how poison works on rodents, right? 

You just place the poison before going to bed, in a place where near the infestation. It takes time for the poison to work and by the time the mouse dies, it is lying somewhere hidden and it could take you several hours to figure it out. The smell may be hard to live with so it’s better to get to work immediately to get rid of it.

When mice die, their bodies start decaying and releasing an overwhelmingly unpleasant smell. Dead rodents carry diseases that could be harmful to the entire family. When ants start swarming on the dead animal, they would go around the house spreading diseases and infecting walls, furniture, ceilings and clothes.  

It also becomes crucial to prevent further mice from coming into your house when you have killed one. It is possible that there is a nest somewhere and needs to be removed straight away. It takes around 12 weeks for the mouse to completely decompose; still, the earlier that the problem is dealt with, the better it is for the health of the household.  Although the smell is really only the first part, and will go away sooner than 12 weeks.  

Identify where the smell is coming from

You need to follow your nose to locate the source of the odor. Protect yourself with gloves, mask and a full-covering suit before undertaking the task. The longer that the source is allowed to stay, the stronger the smell gets, making your house smellier and unhealthier.

Observe whether there are fleas or ants going towards a particular location. Flies and ants gather on dead rodents so if you follow them that could lead you to the source. You may find them in walls or hidden corners around furniture.

When you manage to trace it, remove the rodent, place it in a bag and discard quickly. You should also discard your gloves, mask, suit and clothing that you wore while performing the task because dead animals carry diseases and keeping the clothes would easily spread diseases to the rest of the household belongings.

When the task is accomplished, the odor may still be emanated for several days. For that, daily cleanliness with strong detergents and insecticides becomes crucial.  There are great products that breakdown the organic matter that our noises smell.  Rat sorb, earthcare bags, and air sponges are all the type of products, I would recommend having on hand when you start to bait for rodents.

Clean the house  

For this you would need to stock up on lots of sponges and strong detergents to clean the surfaces. You would need to use a different sponge for each surface, such as wall, counters, attics etc. to prevent the smell from spreading.

Moreover, you would need to use different sponge every day. Clean the house with a sponge, discard it after use then use different sponge the next day. Vacuum the house properly, particularly the dark corners to suck up flies and ants that could have been near the source of the smell. This should be followed by mopping the house with strong-smelling, fragrant and anti-bacterial surface cleaners.

Cleaning the house should be a daily regiment since the smell of a dead animal lingers on for days and it takes several days or proper cleaning and deodorizing to neutralize the odor. Get deodorants for the house, preferably the ones with timers that should be placed in each room. Cleaning is also effective in preventing future infestations.

Rat sorb, earthcare bags, and air sponges are all the type of products, to control and odors. Bacazap is great if you need to work on the urine or feces smell.

Keep your house ventilated

The unpleasant odor would linger on if the house remains humid or if there is a lack of proper ventilation. Clean the house, apply deodorants to rooms and allow air circulation. Switch on the exhaust systems for several hours every day. Keep the windows open for a few hours to let the air in and keep the house dry.

Kill airborne diseases

Apply disinfectants or anti-bacterial sprays everyday to kill all airborne diseases that have been transmitted from the dead animal.

Shut them out

To prevent mice from looking for food and shelter in your house in the future, observe the house from all corners and check for open spaces where the pests could be coming in from. Check for tiny holes in the attic, walls and gaps beneath the doors where something as small as a mouse can easily get in.

Don’t leave food leftovers or crumbs lying around the house or outside the house. That invites not only rodents but other pests and insects as well to feast in your garden; hence, multiply in your vicinity.

Clear the clutter

Check the attic and basement for old furniture or cardboard boxes. Remain organized and discard anything that you don’t need. All that clutter allows rodents to settle and multiply within a short time in your own house and transmit diseases.

If the furniture is infested, discard it as keeping it could transmit diseases to anyone who comes in contact.

Use the techniques in conjunction with each other because eliminating rodent smell completely is a slow and painful process that needs to be repeated for days. The regimen needs to be continued for months to prevent rodents from coming into your house after you have dealt with dead animals.
