How long does the smell of dead rats last?

So How long does the smell of dead rats last?

If you’ve ever had the misfortune to smell a decaying rat carcass, you’ll know just how bad the resulting stench is. If you can get to the rat’s dead body and remove it, the smell should clear out relatively quickly. Unfortunately, this isn’t always possible. Rats have a habit of dying in the most awkward places. Left to decay naturally, the smell of a dead rat can last for a month or more. It takes around three weeks for the carcass to decay, throughout which time the rotting carcass will release pungent gases. Once the rat has fully decayed and the microorganisms feeding on the body stop releasing gases, the smell will still take some time to clear.

No matter what you do, you’re going to have to deal with the smell for a while. Once the decay process begins and the rat’s body starts to smell, it’s too late to prevent it. You can speed things up by keeping your home as well ventilated as possible. Keep as many doors and windows open as possible. If you have to keep most of them shut, try setting up a few small fans to encourage the air to circulate more freely.

How long the smell hangs around will also depend on the materials that absorb to odour. For example, if a rat dies and begins to decay on a carpeted area, the fabrics will absorb and retain the smell much more than a hard, flat surface will. If it’s practical to remove any carpet that comes into direct contact with the dead rat, you should consider doing so. Fabrics in the immediate vicinity might also catch a significant number of aromatic molecules from the decomposing rat. To rid them of the smell, you should wash them using the hottest water you can without damaging them. Some fabrics are more sensitive to high temperatures than others, so be careful.

We thought we had bedbugs but could find no evidence apart from what we thought were bites. I called Bon Accord and Gabriel was there within a couple of hours. He told us we had carpet beetle. Finding the evidence and showing us photos of the skin reaction which was exactly what we had. He advised and returned at a time to suit us to spray which was done thoroughly and efficiently. No sign of the little critters returning. Thank you Gabriel.

Gabriel was absolutely wonderful, a real life saver when I found a mouse by my bed at 10pm. He came in less than an hour and was able to catch the mouse and put my mind at rest so I could go to sleep! Highly recommend, fab service and lovely people.

Gabriel turned up with an hours notice one evening and immediately identified the issued. He works efficiently and professionally throughout with timely follow-ups to ensure the problem was resolved. Once completed he was kind enough to continue to check in to see that the issue had gone. Having had Rentokil previously that spent two years doing very little this was a complete breathe of fresh air and solved the problem in less than two weeks. We are grateful and would highly recommend his services.

We were lucky to have found Bon Accord, they responded very fast to our request and Gabriel was very helpful and informative. He made several visits and did his absolute best until the mice problem we had was gone. Highly recommended.
