What are chiggers?
Chiggers are tiny larvae members of the arachnid family and are sometimes called red bugs. Although the larvae are extremely small in size, their bites pack a powerful punch. They’re so tiny that you probably won’t notice when they jump from that tall blade of grass onto your skin. You won’t feel it as they hitch a ride right into your home. When you eventually do feel them, however, they can be extremely itchy.
Chiggers live in tall weeds and grass, in berry patches, and in wooded areas. They may be in your backyard, by the lake, and clustered along your favorite hiking trail. They are most active on spring, summer and fall afternoons, when temperatures are warm and inviting.
如果您走路并刷在植被的生活的地方，它们可以迅速固定在您的皮肤上。当温度降至60°F（16°C）以下时，Chiggers变得不活跃。当温度下降到42°F（6°C）以下时，它们会死亡。
芝加哥很小，通常需要放大镜才能看到它们。成年人约1/60英寸，有八个腿。幼虫是红色，无翅的六腿生物，其测量小于1/150英寸。由于它们的红色，当它们聚集在一起时，您也许可以发现幼虫。在他们的皮肤上盛宴之后，它们会变成淡黄色的颜色。
只有幼虫咬人。他们倾向于选择身体的温暖，潮湿的区域。Chigger的爪子可以帮助他们抓住皮肤。然后，裂缝将其嘴固定在皮肤上，并注入唾液。唾液中含有一种将皮肤细胞分解为液体形式的酶。
Your body responds by hardening skin cells around the saliva, creating a tube, or a stylostome through which the chigger sucks the host’s body fluids. Chiggers can stay attached and feeding for several days. Usually they last about 4 days before falling off.
Usually several chiggers are able to latch onto a person walking through an infected area. When the chigger falls off, you are left with reddish bumps. You may notice a bright red dot in the center — this is a remnant of the tube your skin formed in response to the chigger’s saliva. The bumps may look like welts, blisters, pimples, or hives.
Chiggers can stay latched to the same spot for several days, and it’s common to be bitten by more than one. So bites will generally appear in groups and get larger for several days to a week.
许多昆虫倾向于咬裸露的皮肤。Chigger喜欢在皮肤的褶皱和衣服紧身的地方咬咬。大多数裂缝都会在脚踝，腰部，腋窝，cor骨或膝盖后面发生。
当缝隙锁定时，您不会感觉到它，当它咬伤时，您可能不会感觉到。但是，大多数人在咬合后数小时内报告症状。叮咬的最有问题的症状是强烈的瘙痒和刮擦的渴望。阴茎上的叮咬会导致严重的瘙痒，肿胀和排尿疼痛。
Chigger咬伤可以恢复一到一到三周。如果您怀疑自己有叮咬，请立即用肥皂和水洗涤。这将摆脱您体内剩余的chi。然后应用防腐剂到任何毛发。
同时，请尝试避免刮擦，因为这可能会导致感染。您可能会使用非处方反诉药物hydrocortisone cream或者灾难性乳液. You can also apply ice to the bites to relieve the itch.
避免使用非常热水和淋浴。如果您被感染或症状无法改善，请去看医生。这是一种普遍的误解，使洞穴在皮肤下面。他们没有，因此无需尝试删除它们。

Chigger bites are uncomfortable, itchy, annoying, and can make it difficult to sleep. In most cases, chigger bites don’t cause any harm to your health. Chiggers feed on skin cells, but not on blood. They don’t carry or transmit disease.
However, chigger bites can become infected from too much scratching. Notify your doctor if you have swelling, fever, or other signs of infection.
春季，夏季和秋季是叮咬叮咬的黄金时间。当您在可能被挑剔的林区时，请尽量不要对植被进行刷新。远足时，走在小径的中心，而不是沿着侧面。
Wear long sleeves and long pants that can be tucked into your socks or shoes. Use insect or tick repellent, especially around the tops of your shoes, shirt neck, cuffs, and waistband. Shower as soon as you go indoors. Wash your clothes in hot water.
