Bed Bug Bite
Is this your child’s symptom?
- Bites from bed bugs
Symptoms of Bed Bug Bites
- Usually cause itchy, red bumps in a group or line
- Often they look like a hive or mosquito bite
- Bite may have a red dot (puncture) in the center. This is where the bed bug bit through the skin.
- Occasionally, a small blister can occur in the center
- Bites are usually on exposed skin (arms, legs and face)
- Bites are usually first noted in the morning
Diagnosis of Bed Bug Bites
- Live bed bugs hide and are not usually seen. Close inspection of the mattress may find some.
- They are ¼ inch (6 mm), flat, oval shaped, reddish-brown bugs.
- Suspect bed bugs if over 3 red bumps in a row are on exposed skin. The bumps or bites are very itchy.
- Bed bug waste is found on bedding or mattress seams. It looks like dark brown flecks or coffee grounds.
- A blood stain on the sheet may sometimes be found. This is from a bug smashed after feeding.
Cause of Bed Bug Bite Reactions
- The skin bumps are the body’s reaction to the bug’s saliva.
- While the bug is sucking blood, some of its secretions get mixed in.
- Bed bugs are small visible blood-sucking bugs. They are about ¼ inch (6 mm) in length.
- During the day, bed bugs hide in the corners of mattresses. They may also be found in bed crevices, floors, and walls.
- At night, the bed bugs come out of hiding. They feed on humans for about 5 minutes.
Prevention of Getting Bed Bugs
- Over half of bed bug infestations within homes start after recent travel.
- Avoid hotels and hostels where bed bugs have been reported.
- When you check into a hotel room, look for signs of bed bugs. Look for flecks of their waste (like coffee grounds) in the bedding and mattress. If present, ask for another room.
- Keep your luggage and clothing on a luggage rack off the floor.
- When you return from a trip, place all travel clothing into the clothes dryer. Run the dryer for 20 minutes. (Reason: The heat will kill any bed bugs or their eggs that are present). One pregnant bed bug can spread bed bugs to an entire house.
Frequent Questions (FAQs)
- Can bed bugs transmit HIV or hepatitis? This is highly unlikely. It has never been reported.
- Do bed bugs like dirt? Not really. What bed bugs like is the warmth of the human body. Dirty and cluttered spaces just give bed bugs a place to hide.
- Are bed bugs too small to be seen? No. You can see adult bed bugs. They are about the size of an apple seed (4-7 mm; ¼ inch).
- Are bed bugs scared of the light? They do prefer darkness. But keeping the light on will not stop bed bugs from biting you.

Care Advice for Bed Bug Bites
-
What You Should Know About Bed Bug Bites:
- Bed bug bites cause itchy red bumps.
- They are usually less than ½ inch (12 mm) in size.
- Some are larger (like a hive). These are normal reactions to a bed bug.
- A large hive does not mean your child has an allergy.
- The redness does not mean the bite is infected.
- Bed bugs do not carry any infectious diseases.
- Don’t panic: You can get rid of bed bugs from your home.
- Here is some care advice that should help.
-
Steroid Cream for Itching:
- To reduce the itching, use 1% hydrocortisone cream (such as Cortaid). No prescription is needed.
- Apply 3 times a day until the itch is gone.
- If you don’t have, apply a baking soda paste until you can get some.
-
Allergy Medicine For Itching:
- If the bite is still itchy, try an allergy medicine by mouth.
- Benadryl is a good one. No prescription is needed.
-
Try Not to Scratch:
- Cut the fingernails short.
- Help your child not to scratch.
- Reason: Prevent a skin infection at the bite site.
-
Bed Bug Repellents – Not Helpful:
- Insect repellents do not keep bed bugs from biting.
- Repellents containing DEET (used on skin) and permethrin (used on clothing) do not help.
-
Removing Bed Bugs from Your Home:

- Look in the phone book or on the internet under Pest Control.

What to Expect:

Bed Bug Bite
This is what a bed bug bite looks like. It can take a few days for the bites to appear after a bed bug bites you. The bites are usually itchy and often have a burning feeling. Try not to scratch and break the skin because this can cause an infection.
Bed Bug
This is a full-grown bedbug. Bedbugs are small brown bugs which are less than ¼ of an inch (6 mm) long. Bedbugs hide in the seams, folds and creases of mattresses and upholstery. They come out at night. During the day, you might see signs of them, such as shed skin, waste or blood marks on the linens.
