When outdoors, rodents such as rats or mice target your home in the hope to find food and shelter. Both rats and mice can squeeze through the smallest of openings and it is therefore impossible to 'proof' a home in the hope to keep them out.
Killing these trespassing rodents with a rodenticide bait can resolve one issue but unfortunately often leads to another issue. This usually occurs when the rodents, who have consumed the bait, can’t be found after they crawl up into the roof void, cavity walls and ceilings where they wind up dying.
As the dead rodents begin to decompose, the odour, their dead carcasses give off, can be terribly awful and very overwhelming. It is important not to just leave the carcasses where it is but to take action to get it removed.
What to do when you smell a dead Rodent?
Locate the source. As soon as you notice what you think is the dead rat smell, start looking for an increased presence of flies, maggots, beetles and other insects that are attracted to dead animals. If flies seem to be hovering or landing near a specific area on a wall or floor, try a “sniff test.” Does the odour seem stronger at that spot? Sometimes bodily fluids seep out of a carcass, so also keep an eye out for stains on sheetrock or ceilings.
Remove the problem. We recommend you leave this to US as the smell is disgusting on its own but there are health risks if the Rat is not handled properly so once you find a dead rat call Dan, Paul of Colin ASAP to come to get rid of it for you.
Removal of all the Rodents friends. Sometimes desperate times call for desperate measures, and the process of extricating one dead rat from your home or vehicle may include cutting through sheetrock or floors, replacing ceiling tiles, pulling up carpets, etc.
The smell which comes from rotting dead rodents is generated by a combination of various chemicals including sulphur dioxide, methane, benzene derivatives and long chain hydrocarbons. This mixture of noxious gases produces a smell that is nauseating and off-putting to nearly all creatures except for perhaps vultures and filth flies. The smell of a dead animal or rodent can linger and produce an even stronger odour with the passage of time as more and more of the rotting carcass decomposes in the span of a 6-10 week period.
