Do Baby Bed Bugs Bite?

Baby Bed Bug After Blood Meal
Baby Bed Bug After Blood Meal

Yes, baby bed bugs bite humans. 

Baby bed bugs, also known as nymphs, are more desperate to bite you as they’re waiting to get their first blood meal. 

Without the first blood meal, the baby bed bugs won’t proceed to the subsequent phases of their life cycle. 

Why Do Baby Bed Bugs Bite?

Let’s understand it this way; if baby bed bugs don’t bite you, they won’t be alive. 

Though bed bugs can go without a blood meal for 20 to 400 days, that’s more applicable to adult bed bugs.

Adult bed bugs can lay dormant for months when the situation is not favorable to them. Or when they don’t have a host to latch on to. 

But if baby bed bugs don’t get their first blood meal, then they won’t be able to molt. 

Molting is the process when the baby bed bugs shed their skin because they’re growing so that they can develop new skin. 

It’s through molting and feeding blood baby bed bugs turn into an adult and breed. 

Baby bed bugs need to molt five times before they turn into an adult. 

And for that, they need blood meals. 

So, now you know why baby bed bugs can be more desperate to bite you. 

One way or the other, their life is dependent on your blood.

Like adult bed bugs, baby bed bugs can’t bite through clothing.

Are Baby Bed Bugs Bite Smaller Than Adult Bed Bug Bites?

Yes, baby bed bug bites are smaller than adult bed bug bites.

Baby bed bugs inject a lesser amount of anesthesia-like anticoagulant in the bitten area than the adult bed bugs.

That’s why the swelling, the rashes, and the itching are minor. 

So, baby bed bugs leave minor or small bite marks.

But if you’re highly allergic to bed bug bites, you may show signs of allergies like swollen and itchy eyes and a watery nose.

If a baby bed bug bites you and you’re getting red lumps and rashes, use an essential oil like lavender on the bite wound. 

That’ would ease the itching a lot. 

But if you’re showing allergic reactions, then see a physician asap.

What Do Baby Bed Bugs Look Like?

Baby bed bugs, or nymphs, are a smaller version of adult bed bugs.

Do Baby Bed Bugs Bite

But there’re two significant differences – their sizes and color. 

There are yellowish-white and translucent. 

They’re translucent till the time they have their blood meal. 

Once baby bed bugs had their blood meal, they’ll look like a tiny red spot. 

Also, baby bed bugs can be challenging to spot with a naked eye because they’re tiny. 

They need regular blood meals so that they can continuously grow through the process of molting. 

How Big Are Baby Bed Bugs?

After they hatch out from the egg, Baby bed bugs are approximately equal to a bed bug egg size. 

The size of baby bed bugs is from 0.077 inches to 0.09 inches. 

They grow up to 0.18 inches to 0.20 inches as an adult bed bug.

Baby bed bugs are flat, and so as the adult bed bugs.

The flat oval shape of baby bed bugs allows them to hide in small cracks and gaps inside your home. 

But baby bed bugs are not fast crawlers. It’s because their legs are not fully developed like adult bed bugs. 

That makes them easy to squish if you could spot them. 

Their inability to crawl fast makes them more prone to hide.

Where Would You Find Baby Bed Bugs?

You’d find baby bed bugs in the same places where the adult bed bugs hide. 

Baby bed bugs tend to follow the adult bed bugs because that assures them a blood meal. 

So, mattresses, headboards, rims of bed frames, soft furnishings like a couch, and dresser drawers are hiding places for baby bed bugs.

How To Get Rid Of Baby Bed Bugs?

You cannot get rid of baby bed bugs without getting rid of adult bed bugs. 

It means that there’s no separate treatment for baby bed bugs. 

But if you observe baby bed bugs in your home, then it’s a severe sign of bed bug infestation. 


It’s because bed bugs are now breeding profusely inside your home. 

An adult female bed bug can lay 200-250 eggs in her lifetime. Each egg takes only a week to 10 days to hatch.
