Why Are Bed Bug Bites So Itchy?

Originally posted on May 25, 2023 @ 4:29 am

Bed bugs are small, wingless insects that feed on the blood of animals or humans while they sleep. When they bite, they inject an anticoagulant and a numbing agent into the skin, which makes it difficult to feel the bite itself. However, once the effects of these agents wear off, the bite can become extremely itchy, often appearing as a red, swollen bump on the skin. In this text, we will explore why bed bug bites are so itchy and what you can do to alleviate the discomfort.

What Are Bed Bugs?

Bed bugs are small, reddish-brown insects that feed on the blood of humans and animals. They are about the size of an apple seed and can be found in cracks and crevices, as well as in bedding, furniture, and clothing. Bed bugs are primarily active at night and are attracted to the heat and carbon dioxide that humans emit.

How Do Bed Bug Bites Occur?

Bed bugs typically bite exposed skin, such as the face, neck, arms, and hands. They use their elongated beak to pierce the skin and inject saliva, which contains an anticoagulant to prevent blood from clotting. The bites are usually painless and may not be noticed until several hours or days later.

One key takeaway from this text is that bed bugs are small insects that feed on blood and are primarily active at night. Although their bites are usually painless, they can cause an itchy reaction due to the immune system’s response to the anticoagulant in their saliva. It’s important to properly treat bed bug bites by washing the affected area, applying a cold compress, and using topical creams or antihistamines. To prevent bed bug infestations, it’s best to inspect bedding and furniture for signs of bed bugs, keep luggage elevated and away from walls, and remember that bed bugs can infest any home, regardless of cleanliness. Eco-friendly options for bed bug control include using diatomaceous earth, essential oils, and plant-based sprays. If bed bugs are present, professional pest control services may be necessary to fully eradicate them.

Misconception: Bed Bugs Transmit Diseases

Contrary to popular belief, bed bugs do not transmit diseases. However, their bites can cause an allergic reaction in some people and may lead to secondary infections if scratched.

The itching sensation from bed bug bites is caused by the body’s immune system reacting to the foreign substances in the bed bug’s saliva. The immune system releases histamine, a chemical that causes inflammation and itching.

FAQs for Why Bed Bug Bites are So Itchy

What are bed bugs?

Bed bugs are tiny brownish-red insects that feed on blood, often at night when their human hosts are sleeping. They can be found in mattresses, headboards, walls, and other furniture. They are notoriously difficult to eradicate once they infest a home or building.

Why are bed bug bites so itchy?

The main reason bed bug bites are so itchy is because these insects inject an anticoagulant and anesthetic into their victims when they feed on blood. This allows them to suck blood without causing pain or immediate itching, but the anticoagulant can cause an allergic reaction that leads to redness, swelling, and intense itching. The itching sensation usually starts a few minutes to a few hours after the bite and can last for several days.

Are bed bug bites dangerous?

While bed bug bites can be very itchy and uncomfortable, they are not usually dangerous. Bed bugs are not known to transmit diseases, so their bites are not a serious health risk. However, scratching the bites can lead to secondary infections if bacteria from the skin gets into the open wound.

How can I relieve the itching from bed bug bites?

There are several ways to relieve the itching from bed bug bites. Over-the-counter antihistamines like Benadryl can help reduce the allergic reaction and ease itching. Applying a cool compress or wrapping ice in a towel and pressing it against the bites can also help reduce swelling and itching. Calamine lotion, hydrocortisone cream, or other anti-itch creams can also provide relief.

How can I prevent bed bug bites?

Preventing bed bug bites involves taking steps to avoid bites in the first place.
