Because flour mites belong to the family of mould mites, they thrive in warm and humid climates. The flour mites usually infest flour, muesli and other dry vegetable foods. The affected products seem to be covered by a coat of light-red dust, crumble, smell sweet and taste bitter. For instance if a cake doesn't rise, the cause can be mites in the flour used. Eating infested foodstuffs can also seriously harm your health.
Allergies can occur that lead to high temperatures and headaches.
Blisters and pustules may form on the skin, and serious stomach and intestinal reactions, even asthma attacks can result from eating food infested with mites.
