How Long Does Dead Rat Smell Last?

For outdoor spaces, once the dead rodent has been disposed and the area is cleaned, the smell should disappear within 24 to 48 hours.

For indoor areas or in the car, it will depend largely on how bad is the situation (the odor), how well is the ventilation of the affected space and the type of odor neutraliser you choose. The placement of the odor neutralisers also plays a big part. That said, we think it can take from days to weeks to completely eliminate the odor. Any longer than that will mean the cleaning was not done properly.

We suggest to spend more time cleaning the area where the rodent has died before moving on to the next step of the treatment. This will ensure that any stains that can be causing the odor is thoroughly removed before removing the odor particles in the air.

[May: Again, do remember that prevention is always better than cure. Once you found the first dead rat at home, be sure to spend some time identifying possible entry point and make effort to block it up properly.]
