As colder, wetter weather starts settling in, mould is likely to become a common problem in many of our homes.
Mould in the house is not only difficult to get rid of, but can even be a serious threat to our health, especially to those with issues like eczema or asthma.
Though mould can be tricky to shift, one common household item that most of us throw away without thinking could be the solution to your pesky problem.
Here’s what you need to know about the unassuming item and the various ways in which it can be used to clean or prevent mould, according to consumer group Which? on Instagram.
What common household item helps prevent mould?
Silica gel packets, which we often find in little sachets in packages we receive, could actually protect your walls and window sills from mould by reducing moisture inside the house.
These tiny packets are designed to prevent moisture from damaging a product, making them perfect for keeping dampness at bay around your home.
One way we can use these packets is using the drying agent inside and popping them on a window sill or in your steamy bathroom to capture some of the condensation.
You can also put the little silica gems inside gym bags or damp shoes to restore freshness, or even near razors and toolboxes to prevent rust from developing.
However, be aware and keep these sachets away from children or pets, as they can be toxic if ingested.
What causes mould?
Mould is caused by excess moisture in the air, which creates a damp environment for fungus to grow.
One of the most common causes is condensation, especially around window sills. Colder, wetter weather can also result in the spread of mould, as does hanging damp laundry in unventilated areas, having a faulty heating system, or a leaky pipe.
While these are some of the reasons for mould to grow in our homes, the true cause may sometimes be hard to pinpoint. It's always a good idea to consult a mould expert to identify the root of the problem, and find a solution accordingly.
What are homemade solutions to mould?

Besides using silica packets, there are a few other homemade solutions to help with mould.
For instance, the natural acids in white wine vinegar have been proven effective in removing certain household moulds, and it's also safe to use when cleaning.
You can easily pick up a bottle at any supermarket, transfer it to a spray bottle and dilute one part vinegar with one part water. Just spray it on surfaces where mould is growing and scrub with brushes or sponges.
Another common ingredient in our kitchens that can remove mould is baking soda. A mildly abrasive cleaning agent, baking soda not only gets rid of mould, but also eliminates odour and moisture.
Simply use equal parts of baking soda and water to make a paste, then apply this paste to mould-infested areas. Once the paste dries, scrub it away with a brush and clean the area with a damp cloth.
