Since Dust Mites Don’t Bite, What Bugs Could Be Biting Me?
Here are a few biting pests that are common in homes.
- Bed Bugs are small, oval, often brown insects that live on blood from either humans or animals. Unlike the microscopic dust mite, they can grow as big as an apple seed and will bite any area of exposed skin. These bites can turn into itchy welts and can be found anywhere on the body. If you see dark specks along the
mat t ressseams or rusty reddish stains, you might have a bed bug infestation.
- Fleas Area probably the most common culprit of nighttime bug bites. They can especially be an issue if you own pets and don’t realize that one of them has become infested. Flea bites typically bite a person on the ankles and often appear red and sometimes blotchy with a red spot in the center.
- Chiggers are microscopic outdoor only mites. If you have been outside in a swampy, grassy, weedy, or moist environment, you may have gotten the bites before going to bed. Sometimes the itching won’t start for several hours. Bites usually occur under socks or areas where clothing is tight.
- Mosquitos are worth mentioning as they sometimes get inside a home and settle into bed with you. Mosquito bites appear as small raised welts, often colorless, and come with intense itching.
What Are the Best Treatments for Bug Bites?
Depending on which type of bug bites you, there are different treatment options available.
- Treating Bed Bug or Flea Bites should be treated with a hydrocortisone skin cream such as Cortaid. If you are prone to allergies you may also want to take an oral antihistamine like Benadryl.
- Treating Chiggers The itching is not caused by the initial bite, but from the parasitic larvae that the adjust lays under your skin when it bites you. However, the best treatment is exactly the same as it is for bed bugs or flea bites. Do not put clean nail polish on your skin! This is a home remedy that is an old wives’ tale and does not work.
- Treating Mosquito Bites First off, do not scratch the area! Instead, lightly wash the area with cool water and soap. Put on some calamine type lotion or some Cortaid. Baking soda paste has also been known to work well.
If you are unsure what has bitten you, the safest course of action is to just wash the area and apply hydrocortisone skin cream. If you think you might be having an allergic reaction, call your doctor or visit an urgent care facility as soon as possible.
