though dust mites are difficult to find and see, they nevertheless can cause serious allergy issues for some homeowners

DUST MITES Dust mites are tiny, microscopic creatures that feed on human and animal skin flakes. Dust mites are invisible to the naked eye, but their adverse health effects are evident in 20 million American residents. You probably have thousands of dust mites in the furniture, floors and windowsills around your home or business. They are a common indoor allergen, and exposure to dust mite allergens can trigger allergic reactions in sensitive individuals. The primary allergens produced by dust mites are found in their feces and body fragments. These allergens become airborne and can be inhaled or come into contact with the skin, leading to various allergic symptoms.

Common allergic reactions to dust mite allergens include:

  • Respiratory Symptoms: Inhaling dust mite allergens can cause symptoms such as sneezing, runny or stuffy nose, itchy or watery eyes, coughing, and wheezing. Individuals with asthma may experience exacerbation of their symptoms.

  • Skin Irritation: Direct contact with dust mite allergens or contaminated surfaces may lead to skin irritation, redness, or itching.

  • Eczema Flare-ups: People with eczema (atopic dermatitis) may experience flare-ups or worsening of their skin condition when exposed to dust mite allergens.

It's important to note that dust mites thrive in warm, humid environments, and they are commonly found in bedding, mattresses, pillows, upholstered furniture, and carpets. If allergic symptoms persist or are severe, individuals should seek advice from an allergist or healthcare professional for proper diagnosis and management, which may include medications to control symptoms or allergen immunotherapy for long-term relief. Your Nelon-Cole technician has safe, effective solutions to help rid your home of dust mites.

stink bug infestations are commonly found in homes across the carolinas


Stink bugs, also known as shield bugs, belong to the family Pentatomidae. While they are primarily known for their unpleasant odor emitted as a defense mechanism, they are not typically associated with causing allergies in humans. The odor is produced by the release of chemicals when the bugs feel threatened.

However, it's worth noting that some people may experience skin irritation or allergic reactions upon direct contact with the secretions or bodily fluids of stink bugs. These reactions are generally mild and can include redness, itching, or a rash at the contact site. In rare cases, individuals with heightened sensitivity may experience more severe skin reactions.

If you come into contact with stink bugs or their secretions and develop skin irritation, it's advisable to wash the affected area with soap and water. Applying a mild anti-itch cream or taking an antihistamine may help alleviate symptoms.

While stink bugs themselves may not be a common cause of respiratory allergies, their presence indoors can sometimes lead to the growth of mold. Stink bugs are attracted to warm indoor environments during cooler months, and their droppings can contribute to mold development. Mold allergies, rather than stink bug allergies per se, could be a concern in such cases.

If you suspect that exposure to stink bugs or their environment is causing allergic symptoms, or if you experience severe reactions, it's recommended to consult with an allergist or healthcare professional for a proper evaluation and guidance on managing symptoms.
