Dust Mites

What They Are

Dust mites are microscopic creatures that thrive in humid, and warm places. They eat dead skin cells and are found in carpets, upholstered furniture, and bedding. Dust mite droppings are a major allergen and can trigger asthma and allergy symptoms.

How to Eliminate Them

To reduce dust mites, wash bedding weekly in hot water and use dust mite-proof covers on mattresses and pillows. Vacuum carpets and upholstery regularly with a vacuum that has a HEPA filter. Maintain low humidity levels in your home by using a dehumidifier and ensuring good ventilation.

Pet Dander

What It Is

Pet dander can remain airborne for a long time and is a common trigger for allergies. Some examples are skin shed by animals with feathers or fur like rodents, cats, and dogs.

How to Eliminate It

Regularly bathe and groom your pets to reduce the amount of dander they produce. Keep pets out of bedrooms and off furniture to minimise exposure. Vacuum your home frequently using a vacuum with a HEPA filter, and consider using air purifiers to help remove airborne dander.


What It Is

Mould is a type of fungus that grows in damp, humid environments. It releases spores into the air, which can cause allergic reactions and respiratory issues. Common places for mould growth include bathrooms, kitchens, and basements.

How to Eliminate It

To prevent mould, control humidity levels by using dehumidifiers and exhaust fans. Fix any leaks and ensure proper ventilation in damp areas. Clean mouldy surfaces with a mixture of water and vinegar or a mould-specific cleaner. Remove and replace any materials that are heavily infested with mould.

What It Is

Pollen is a fine powder produced by plants for reproduction. It can enter your home through open windows, and doors, and on clothing or pets. Pollen is a common allergen that can cause hay fever and other allergic reactions.

How to Eliminate It

Close the doors and windows during high pollen seasons. Don’t forget that air purifiers with HEPA filters are effective in reducing indoor pollen levels. Change clothes and shower after spending time outdoors to remove pollen from your body. Regularly clean and dust your home to prevent pollen accumulation.

Cockroach Droppings

What They Are

Cockroach droppings and saliva contain proteins that can trigger allergies and asthma. These pests are commonly found in warm, moist areas such as kitchens and bathrooms.

How to Eliminate Them

Keep your home clean and free of food crumbs and spills to deter cockroaches. Seal cracks and crevices where cockroaches can enter. Use bait stations, traps, or professional pest control services to eliminate existing cockroach infestations. Regularly clean areas where cockroaches are likely to be found.

Regular Cleaning Practices

Frequent Dusting and Vacuuming

Regular dusting and vacuuming are essential to reduce the presence of allergens in your home. Dust surfaces with a damp cloth to prevent dust from becoming airborne. Use a vacuum with a HEPA filter to trap allergens effectively. Aim to vacuum at least twice a week, focusing on high-traffic areas and places where pets spend time.

Use of Air Purifiers

Benefits of Air Purifiers

Air purifiers with HEPA filters can help remove airborne allergens such as dust mites, pet dander, pollen, and mould spores. Place air purifiers in commonly used rooms, like the living room and bedrooms, to improve air quality. Regularly change the filters according to the manufacturer’s instructions to maintain their effectiveness.

Allergen-Proof Bedding

Invest in Allergen-Proof Bedding

Using allergen-proof bedding can significantly reduce exposure to dust mites and other allergens. Look for mattress and pillow covers that are specifically designed to block allergens. These covers can prevent dust mites from penetrating and thriving in your bedding.

Proper Ventilation

Importance of Ventilation

Proper ventilation helps reduce indoor humidity and improves air circulation, which can prevent the growth of mould and the accumulation of other allergens. Open windows regularly to allow fresh air to circulate. Use exhaust fans in bathrooms and kitchens to remove moisture and prevent mould growth.

These services often use specialised equipment and techniques to remove allergens from carpets, upholstery, and air ducts. Consider scheduling professional cleanings periodically to maintain a healthy home environment.
