Acarus siro, also known as the flour mite, can technically live anywhere across the USA with the right conditions. They are ubiquitous and resilient, and most commonly found in homes, particularly in high humidity areas like kitchens and bathrooms.

Industry Presence

• Agriculture and Farming: These mites are prevalent in farming environments, particularly those growing commodities like wheat, corn, and other grains.
• Food production facilities: Acarus siro is often found in food storage and production facilities, specifically areas storing or processing flour, grain, cheese, and dried fruits among others.

Despite the fact that they can be brought home from these environments, they are more prevalent in certain geographical areas.

Geographical Preference

• Coastal States: The higher humidity of coastal states provides a favourable environment for these mites, especially in the Southern and Eastern parts of the USA.
• Northern States during summer: During the humid summer months, these mites can become more common in the northern states.

Acarus siro, commonly known as the flour mite, is a common allergen often found in stored foods, especially those containing wheat or corn flour, cereals, dried fruits, cheese and other dairy products. Consuming these foods may exacerbate symptoms for those with an Acarus siro allergy.

Avoid Foods Containing Wheat or Corn Flour

• Bread and Pastries: These are typically made with wheat flour, which may contain flour mites.
• Cereals: Many cereals are made from corn or wheat, and therefore may trigger an allergic reaction.

Avoid Certain Dairy Products

• Cheese: Flour mites are often found in cheese, which may worsen allergy symptoms.
• Butter and Milk: These also frequently contain flour mites and should be avoided by individuals allergic to Acarus siro.

Avoid Dried Fruits

• Raisins, Prunes, Apricots: Dried fruits are another common source of flour mites, and may lead to allergy flare-ups.

Please note that not everyone with an Acarus siro allergy will have the same food triggers, so it's important to identify and avoid the particular foods that aggravate your symptoms.
