危害
1．局部异物反应，引起局部炎性病变。如毛脂器官堵塞，刺激角质层增生，毛囊扩张，毛孔粗大，毛囊营养不足，毛发脱落等病变。皮脂过度分泌，导致油光满面。
2．螨虫侵入睫毛毛囊内和皮脂腺内，可造成眼睑缘发炎，睫毛松脱等现象。
3．螨虫对头发的危害：毛囊螨刮吃发根的毛根壁，从而吸取供给到毛根的营养成分，使头发的根部变细，根部动摇、开始脱发，成为头屑、头部瘙痒、头皮疾患、粗糙头发和脱发的原因。
4．螨虫对皮肤的危害：螨虫在皮肤里面吸取营养成分，刺激毛细血管以及细胞组织，引向皮肤恶化。皮肤螨虫加速细小皱纹的产生，加速黄褐斑、雀斑、黑斑等色素沉着，还可导致粉刺、痘疤、痤疮、皮肤粗糙、角质变厚、形成凹凸皮肤。皮肤螨虫还能形成瘙痒症、酒糟鼻以及红脸、红血丝等。
5．螨虫是皮肤传染病的媒介体：皮肤中的螨虫不分昼夜随时出入皮肤内外。螨虫爬到皮肤表面将皮肤表面的化妆品渣子、各种污染物质、细菌等异物粘到身上带到皮肤里。如果皮肤抵抗力弱，则会引起皮肤炎症。
6．造成黑色素代谢紊乱、色素色斑沉积。
7．螨虫过敏性反应：我们生活着的室内空气中每一克空气中都发现数十只——数千只的螨虫，种类达20-40种。为了找出成人遗传过敏性皮肤炎的原因而测试的结果发现，50%以上的人对螨虫呈阳性反应。
床上危害最大
1．床是螨虫最适宜生长繁殖的小窝。
2．人一天中起码有7到8个小时在床上度过，而这些床上用品与人体皮肤有着最直接的接触，这给螨虫入侵提供了绝佳的机会！
3．因为螨虫喜湿怕光，晚上睡觉时阴暗的环境加上有“你”这么一块大美食，是螨虫觅食和活动的最佳时机！
赶走螨虫---自己动手的方法编辑
Wash your bedding once a week with hot water.While this is not energy efficient, cold water will not kill dust mites.
1每周用热水（55度以上）洗一次床上用品（床单，被罩，枕套， 被子心，褥子心，枕头心）。这种方法虽然浪费能源，但是常温的水无法杀死螨虫。
Eucalyptus essential oils kill dust mites. Combine2 cups of distilled water, 5 drops of organic liquid soap and 30 drops of eucalyptus essential oil, and spray it on your bed daily to keep the dust mites at bay.
2 尤加利树（又名：桉树）提取的精油可以杀死螨虫。调配比例：1×杯水，5×滴洗手液，30×滴尤加利树（桉树）提取的精油。把他们完全混合，然后每天用他们喷你的床上用品让螨虫陷入绝境。 (各大商场都有，牌子没所谓，可以去网上淘大瓶的外国货，比国产的便宜)
Purchase a dehumidifier.This will help regulate humidity which will make it less inhabitable for dust mites.
除湿器，这会降低正常的室内湿度，有利于减少螨虫（螨虫喜欢阴凉潮湿的环境，这个普通空调也可除湿）。
Purchase an organic, natural latex mattress.These mattresses fight dust mites andare free of fire retardants and synthetic chemicals, which are sprayed on most traditional mattresses. These are about double the cost, butwell worth it.
橡胶床垫。这种床垫是在普通的床垫上喷上一种特殊的化学合成物，这种床垫抗螨虫并且防火。 虽然价钱是普通床垫的两倍，但是这钱花的值得。
Purchase all-natural, untreated organic dust mite pillow and mattress covers. They are a small investment, and can help eliminate dust mites from your bedding.
使用抗满的枕头套和床垫套（因为老外不用褥子，所以中国小伙伴要记得把褥子和床垫一起套在里边哦）。小的花销却可以使螨虫远离你的床上用品。
Purchase an air mattress. Dust mites can’t inhabit this inexpensive bedding alternative.
或者使用充气床垫。螨虫也没法在这种床垫里生长，便宜但是可以凑合用。
Carpet is a breeding ground for dust mites, and the best option is to eliminate it from your home altogether. If you can’t do this, vacuum with a HEPA filter.
地毯是螨虫最爱之一。 最好是整个家里一起清理。如果不能实现，可以用HEPA过滤网的吸尘器
Dust with a damp cloth so it actually collects the dust mites instead of spreading them. Add a few drops of organic eucalyptus and wintergreen essential oils to the damp clothto kill the dust mites while you collect them.
用拧干的抹布擦拭（半湿半干的那种），不要用鸡毛掸子掸灰。在抹布里加几滴尤加利的精油（桉树油）和冬青精油，用来杀死螨虫。
Put items such as blankets, sheets, pillows andcurtains in a plastic bag in the freezer for 48 hours. This will kill the dust mites. Make sure you wash these items after they have been in the freezer to ensure the residue from the mites is gone.
把所有的东西都用塑料袋打包放冰箱里冷冻48小时（毯子，床单，枕头，窗帘）。这样会杀死螨虫。 要注意，冷冻后也要清洗一遍，这样会除掉螨虫的残留物（螨虫粪便，螨虫尸体等过敏源）
Dry your bedding in a hot dryer. This will kill any dust mites that lived through the washing cycle.
使用衣物烘干机烘干床上用品。这能杀死洗衣后仍没杀死的螨虫（主要针对冷水洗涤杀不死的螨虫）
Consider throwing away pillows that are 6 months to 2 years old. Down pillows and comforters attract the most dust mites, and they cannot be cleaned conventionally to get rid of dust mites. After 2 years, your pillows' weight may be 10 to 15 percent dust mite waste.
Replace pillows and comforters with those that can be cleaned in a conventional washer and dried in a dryer.
考虑扔掉旧的枕头（6个月-2年）。 羽毛枕头被子和毛绒玩具不容易用水洗，又特别爱招螨虫。对于一个枕了2年的枕头，其重量的10%-15%都是螨虫的排泄物（过敏源）。把枕头和被子换成容易经常用水清洗，并且可以用衣物烘干机烘干的材质。
Cover your mattress, mattress pad and pillows with allergenic covers. If possible, use the plastic options, since dust mites cannot live in plastic, like they do in fabric.
用防过敏的床垫套，枕头套（国外床品防过敏就是指床上的螨虫过敏）。建议选择塑料制品，尘螨无法在塑料里生存。（国外的防螨床上用品大多是里层是塑胶的，不透气，不透水，但外层是防螨的透气材质）。
Consider replacing old carpet with linoleum. Carpet is a breeding ground for dust mites, especially if you have pets.
Regularly steam clean your carpets. If possible, use water that is over 130 degrees Fahrenheit (54 degrees Celsius).
移除地毯。不要地毯最好了，如果蒸地毯，最少要55度以上。
对于有宠物的人
Brush your pets daily while you are outdoors. Use a stroke that is with the hair and also against the hair, to get rid of more pet dander.：
每天在室外给宠物梳毛。每天用毛刷子在户外给狗梳毛，省得在家里掉毛。
Wipe your pets' fur with a damp washcloth when they come in from outside. This will also remove pet dander that lands on carpets, bedding and furniture.
宠物从户外回来的时候都用拧干的抹布擦它们全身。可以防止头皮屑和到处掉毛
。Vacuum in areas that your pets like to frequent every day, if the dust mite problem is bad
宠物最喜欢呆的地方要每天吸尘
Replace pet bedding regularly.
经常更换布艺的狗窝，猫窝
Keep your pets outside of your bedrooms. They will add to dust mite problems, since the number of people and animals that use a room will correlate with how big the dust mite population is.
别让宠物进卧室，招螨虫
Schedule a dust mite removal cleaning of mattresses every 3 to 6 months. Places that are humid and above 70 degrees Fahrenheit (21 degrees Celsius) on average will benefit the most.
找专业的清理床垫螨虫的公司清理。70度以上蒸汽。
Make sure that carpet cleaning includes an anti-dust mite chemical. These can be more expensive than regular carpet cleaning solutions, but they can kill large populations of dust mites in the carpet.
用杀室内螨虫的专业清洁液清洁地毯。（这个可以去网上找找，国外这种东西很普遍，一般200人民币左右的粉末或喷雾可以用很长时间。）
A simple way to prevent dust mites in your bedding is to place a waterproof, breathable protector on your mattress and pillows. These type of covers are machine washable. Wash them as often as you wash your sheets, which is best every weekend. Dust mites need food and water to survive. Keeping the protectors washed will keep them free of food for dust mites and the waterproof material keeps moisture out of the bed and pillows. These simple steps will prevent dust mites from congregating in your mattress.
最简单的方法。把你的床上用品（枕头套，被套，床垫套三者一起效果最好）换成防水，透气的材料。这种材料的床垫套可以直接用洗衣机洗，就像洗其他床单被罩一样，每周扔洗衣机里洗一下。螨虫需要水和食物。你对这种材料的洗涤可以让螨虫没吃的，而这种材料可以阻止你的汗液渗入，让它们没吃没喝。这样你就胜利了。
