5 Reasons Why Can bed bugs bite one person and not the other?

There’s always a shroud of mystery that revolves around bed bug bites. 

Many people who’ve got severe bed bug infestation in their homes don’t get bed bug bites!

But bed bugs make the lives of other people living in the same home miserable by biting them all over the body.

Many of our women readers have asked us, “why do I wake up with bed bug bites, but my husband does not?”

Can bed bugs bite one person and not the other in the same bed?

In this guide, you’ll find out what’s behind this strange phenomenon. 

And is it really the bed bugs that are biting you or something else?

Keep reading to know the truth behind the mystery.

How Can Bed Bugs Bite One Person And Not The Other?

can bed bugs bite one person and not the other

In all honesty, no, it doesn’t happen.

If there are bed bugs in your bed, then bed bugs will bite the other person who’s sleeping with you in the same bed.

So, why are you the unlucky one who’s waking up with bed bug bites? And not the other person who’s sleeping right beside you

There can be five reasons for it. Let’s find them out.

#1 – Bed Bugs Did Bite You Days Ago, And You’re Reacting Now!

According to the CDC, bed bug bites can take up to 14 days to appear in some people.

On some people, the welts and red rashes are visible after waking up from sleep.

So, even though bed bugs bit you days ago, you’re getting the signs of bed bug bites right now.

In that case, the chances are quite high that the morning you’re getting the lumps, bed bugs didn’t bite you the night before.

The reality is that bed bug bites take different periods to appear in different people.

#2 – The Person Sleeping On The Same Bed Isn’t Reacting To Bed Bug Bites.

Let’s face it, the rashes, soreness on the skin, and the welts are reactions to bed bug bites. 

Some people react, and some people don’t.

If the person sleeping on the same bed with you isn’t showing any sign of bed bug bites, it doesn’t mean that bed bugs are not biting him or her.

Why a person doesn’t react to bed bug bites is beyond the scope of this post, and frankly, we’re not the medical experts to tell you that.

But the truth is that not everyone reacts to bed bug bites. People who’re sensitive to bug bites develop the signs of bed bug bites faster than people who aren’t.

#3 – Something Else Is Biting You, Not Bed Bugs

Not all bites you get on the bed and couch are from bed bugs. 

Many other tiny biting bugs live in these places with soft furnishings.

Fleas, ticks, and mites are a few of them. 

And as these bugs are minute and hard to spot, that also makes you wonder what’s biting you that you can’t see.

In our post on microscopic bugs that bite, you’ll find the list of invisible bugs that bite but you can’t see.

You’ll also find out how you get those bugs in your bed and your home and how you can get rid of them.

#4 – Bed Bugs Prefer Your Blood Type

Now, this can be the slimmest of reasons why bed bugs are biting you but not the one who’s sleeping with you on the same bed.

Let’s clarify first, bed bugs and other blood-sucking bugs don’t have a preferable human blood type.

Experts are still trying to figure out if bed bugs prefer a particular blood group.

However, bed bugs are attracted to the warmth your body emits and the carbon dioxide you exhale while you’re asleep.

That’s why bed bugs bite you mostly while you’re asleep.

In general, people with blood type “O” are warmer than people with other blood types.

That’s why people with “O” blood groups are more prone to get bed bug bites.

But there’s a catch. 

When it comes to body temperature, women are slightly warmer than men. That makes the bed bugs bite women more than they bite men.

It can be a possible reason why you get bed bug bites while your husband doesn’t.  

Also, over time, bed bugs get used to the blood of the primary dweller in the home.

It’s because the bed bugs have been getting their blood meals from the same person. That’s the reason why someone new moves in bed bugs bite him or her pretty late.

So, if your blood type is, say, A+, and bed bugs have been feeding on your blood, then bed bugs won’t bite the new person even if he or she has O- blood type.

But there’s one research that confirmed that bed bugs hate alcoholics. They’ll not feed on the blood of the people who drink regularly.

Now by this statement, we don’t mean that you should often drink alcohol to stop bed bugs from biting you while you’re asleep. We don’t recommend that. 

We’re only quoting a research study that stated bed bugs don’t feed on blood contaminated with alcohol.

#5 – There Are Mold Mites In Your Home That Are Causing The Bed Bug Bite Signs

Now this one is the most often ignored reason for getting bed bug bite marks on your body. 

Yet, there are many instances when mold mites are the reason for causing symptoms of bed bug bites on your skin.

Mold mites are tiny mites that feed on the mold on your home’s walls, furniture, and floor.

Mold mites are present in homes with high dampness, and they also come out of the HVAC system.

These mold mites have tiny hair, which causes itchy red sores that last as long as the bed bug bite marks last when they stick with your body.

The welts will also secrete a yellow viscous liquid if you scratch and itch the bite marks often.

It’s pretty common to residents of many homes that don’t even have a single mosquito or any biting bug in their bed and home, but their homes are damp.

The best way to deal with mold mites is to reduce your home’s dampness levels and clean your HVAC system.
