We all know that a fresh-smelling home is a clean and comfortable one. However, sometimes we may notice that our carpets have a subtle (or not-so-subtle) odour that lingers no matter how much we clean. 

This blog post will expose the hidden causes of carpet odours and provide valuable tips on eliminating them for a fresher, more inviting home.

Cause 1: Trapped Moisture

One of the most common causes of carpet odours is trapped moisture. This can occur for various reasons, such as spills, leaks, or high humidity levels in your home. When moisture becomes trapped in your carpet, it creates the perfect mould and mildew growth environment, producing a musty, unpleasant smell.

Solution: To tackle trapped moisture, act quickly when spills occur by blotting the area with a clean, dry cloth. Use a wet vacuum to extract the moisture for larger spills or leaks. To prevent mould and mildew growth, use a dehumidifier in rooms with high humidity levels and consider investing in a moisture-resistant carpet pad. Regular carpet cleaning with a steam cleaner can also help to remove any lingering moisture.

Cause 2: Pet Stains and Odors

As much as we love our furry friends, they can sometimes be the culprits behind unpleasant carpet smells. Pet stains, such as urine or feces, can seep deep into the carpet fibres and padding, causing persistent odours that are difficult to eliminate.

Solution: To combat pet odours, clean up accidents as soon as they happen using a pet-specific stain and odour remover. This will help break down and neutralize the odour-causing compounds in pet waste. Regularly vacuum your carpets to remove pet hair and dander, and consider using a carpet deodorizer specifically designed for pet owners. If odours persist, it may be necessary to have your carpets professionally cleaned or replaced, especially if the padding has been contaminated.

Cause 3: Smoke and Cooking Odors

Smoke and cooking odours can also contribute to a smelly carpet. If you smoke indoors or frequently cook strong-smelling foods, these odours can become trapped in your carpet fibres and linger long after the smoke or cooking has ceased.

Solution: The best way to prevent smoke and cooking odours from permeating your carpets is to ensure proper ventilation. Open windows and use exhaust fans when cooking to help dissipate strong smells. If you smoke, consider doing so outdoors or in a designated area with good air circulation. Regularly vacuuming your carpets can help to remove surface odours, and using an air purifier or odour-neutralizing products can also be beneficial.

Cause 4: Dirty Vacuum Cleaner

Ironically, the tool you use to clean your carpets could contribute to their odour. Over time, dirt, debris, and even mould can accumulate in your vacuum cleaner, causing it to emit a foul smell when in use. This can transfer to your carpets, making them smell even worse.

Solution: To keep your vacuum cleaner fresh and odour-free, clean it out regularly according to the manufacturer’s instructions. This may involve emptying the dustbin, replacing the bag, washing the filters, or wiping the interior with a damp cloth. Regular maintenance will not only prevent odours but also help your vacuum cleaner to perform at its best.

Cause 5: Bacteria and Germs

Finally, bacteria and germs can be hidden causes of carpet odours. Dirty carpets can harbour various microorganisms, including bacteria, that produce foul-smelling gases as they break down organic matter.

Solution: To keep your carpets fresh and free of bacteria, vacuum regularly and deep-clean your carpets at least once a year, either with a steam cleaner or by hiring a professional carpet cleaning service. You can also use a carpet sanitizer or disinfectant spray to kill germs and eliminate odours.


The key to a fresher home and eliminating hidden carpet odours lies in understanding the causes and taking appropriate measures to prevent and destroy them. You can still enjoy a clean and inviting home free of unpleasant carpet smells by addressing trapped moisture, pet stains, smoke and cooking odours, vacuum cleaner maintenance, and bacteria.
