The life stages of dust mites are eggs, larvae, protonymph, deutonymph, tritonymph, and adult males and females. The length of the life cycle depends on the temperature, while the relative humidity (RH) exceeds 60%. At 23°C, the lifecycle lasts 36 and 34 days for D. The full life cycle of a dust mite, or the transformation of an egg into an adult, lasts about a month.
Dust mites live for an additional period of time in adulthood, in most cases depending on their gender. The four main stages of dust mite development are the egg phase, the larva phase, the protonymph phase, and the tritonymph phase (before becoming an adult mite). For the two nymphal stages to occur, dust mites must shed or shed their hard exoskeleton, or protective layer of skin, so that the softer tissue underneath can grow and expand. Usually, the dust mite lives a total of three months.
The mated adult female can lay 40 to 80 eggs over the course of her life. When the egg hatches, a six-legged larva emerges. There are two nymphal stages that feed and molt before an eight-legged adult develops. The adult house dust mite has an appendage similar to a mouth, but it has no eyes or antennae.
The duration of the cycle is usually one month, but it depends on the weather, ideally 25°C and a relative humidity of 75%. An adult house dust mite can live for one to three months under favorable conditions. The average life cycle of a house dust mite is 65 to 100 days. A female house dust mite that mates can live up to 70 days and lay 60 to 100 eggs in the last five weeks of her life.
Within 10 weeks of life, a house dust mite produces approximately 2000 fecal particles and an even larger amount of partially digested, enzyme-coated dust particles. When a person experiences an allergic reaction that they think is dust, it is likely a reaction to the dust mite's hairs or to the dust mite itself.
Household dust mitescan produce up to 20 droppings a day, and each canister contains 14 fully identified potential allergens, many of which are enzymes. Dust mites play an important role in their natural habitat and can rarely be replicated by other organisms, although they are often perceived as domestic pests.
House dust mites are arachnids, not insects, and are related to ticks and spiders, like the long legs of parents. The predators of dust mites are other allergenic mites (Cheyletiella), silverfish, and pseudoscorpions. Covering mattresses and pillows with products that have proven allergen barrier properties is effective in reducing exposure to house dust mites and their allergens. To be able to see them, dust mites must be magnified several hundred times, most of the time with a microscope.
Household dust mites contain approximately 75% of water by weight and, therefore, need to absorb water from water vapor present in the air, so relative humidity is a fundamental factor for their survival. The airmid healthgroup allergen laboratory offers a full range of advanced allergen analysis services, specializing in allergen protection services, dust mite-related testing, claims verification services and allergen detection. However, dust allergies aren't usually caused by the dust itself, but rather by tiny, insect-like creatures known as dust mites. During the life cycle of these creatures, their eggs grow through four different stages until they reach adulthood.
Dust mites are microscopic arachnids related to ticks and spiders that have no eyes or antennae. Dust mites can live up to three months under favorable conditions such as 25°C temperature and 75% relative humidity. A female house dust mite that mates can lay up to 100 eggs in her lifetime while producing 2000 fecal particles and an even larger amount of partially digested enzyme-coated dust particles every 10 weeks. Allergies caused by these creatures are usually due to their hairs or droppings which contain 14 identified potential allergens.
The airmid healthgroup allergen laboratory also provides specialized services for allergen protection from these creatures.
