The arachnids live in the ground, where they lay their eggs and the larvae hatch in the summer. Not the adult grass mites but the orange-red larvae are responsible for the stings. In warm weather, the approximately 0.3 millimeters larvae come to the surface. The mites and larvae are very small and not visible to the naked eye.

They collect in bright and slightly damp places, for example on meadows and in gardens. For their further development, the larvae need humans and animals as hosts. The grass mite bite primarily affects the ankles, knees, loins and armpits. The larvae have a biting tool to penetrate the skin. In the grass mite bite, an enzyme contained in the animals' saliva enters the wound and dissolves the uppermost layer of the skin.

This leads to nodules and wheals, which sometimes occur only hours after the grass mite bite. The itching, which is also triggered, can become even more intense three days later and last up to two weeks. The affected person does not notice the grass mite bite itself, as the mouthparts penetrate only fractions of a millimeter. The animals feed on the lymph fluid and on the cell sap, not on blood.

causes

The grass mites, also known as autumn, autumn grass and harvest mites, sneak up on their legs to their victims, who are warm-blooded humans and animals. The larvae perch in colonies on grass stalks, in the bushes or on the ground. When a creature passes by and has optimal operating temperatures of about 30 to 40 degrees Celsius, the larvae settle on the host.

They usually get on their feet, from which they walk up their legs and bite into suitable places. There, the grass mite bite leads to an unbearable itch. The larvae like to find pleasant places that include warm and humid areas, such as the edges of socks, the waistband, underwear, armpits.

If the larvae have eaten to about three times the size of the grass mite bite, they will fall. In the next four to six weeks they will turn into a nymph.
