Halifax

Coastal cities like Halifax may be able to enjoy their proximity to the ocean, but for dust mites, warm and humid air is the perfect combination to thrive. Invisible to the naked eye, dust mites are tiny spider-like insects, which come from the breakdown of household fabrics and furniture, as well as human and animal dander. With symptoms similar to hay fever, including sneezing and runny nose, many people with dust mite allergies also experience signs of asthma. Although dust mites are a universal allergy like cat, regions with a humid climate often see higher levels of this allergen.
