What Do Baby Bed Bugs Look Like? 

If you’re experiencing mysterious bites on your body or spot small bugs in your bed, you may have a bed bug infestation. One of the most challenging aspects of dealing with bed bugs is identifying and eliminating their younger counterparts.

These tiny insects are capable of biting you and causing discomfort, but they can be more challenging to detect due to their small size and translucent appearance.

In this post, we’ll share the information you need to know about the bed bugs baby, including their appearance, behavior, and life cycle stages. We’ll also discuss whether their bites look the same as adult bed bugs and include tips for getting rid of them. 

Key Pest Points:

•  Baby bed bugs start small, measuring approximately 1.5 mm when they hatch, but can grow to 5-6 mm once they mature. 

•  They are typically whitish, transparent, or straw-colored, but become reddish-brown after feeding on their first blood meal. 

•  The bed bugs babies go through five molting stages before becoming adults, and after each molt, they become larger and change in color from translucent to light tan. 

Baby Bed Bug Identification

Baby bed bugs, also known as nymphs, are small bed bugs. They grow and shed their skins five times, just like a baby roach, leaving behind exoskeletons for each bed bug in your home.

During the nymph stage, baby bed bugs require a blood meal to advance to the next stage of development. Without a meal, they won’t be able to progress to the adult stage.

Typical Sizes of Baby Bed Bugs

Bed bugs start small, measuring approximately 1.5 mm when they hatch, but can grow to ¼ inch once they mature. While all stages of bed bugs are observable without magnification, individuals with poor eyesight may experience difficulty spotting them.

In their initial stage, bed bugs are comparable to a pinhead, gradually expanding until they attain full size, similar to an apple seed. 

When they hatch, nymphs seek food, and their bodies become filled with blood, giving them a reddish-brown color that makes them easier to spot.

Compared to adult bed bugs, they are more cylindrical and have narrower, flatter bodies. Like many pool bugs, they have six legs, but their legs and antennae are shorter. 

Stages of Development

The first stage of a baby bed bug’s life is the egg, followed by five nymph stages or molts which they go through as they grow. Each molt results in an increase in size and a change in color from white to light tan.

Fourth instarApproximately 3 mmTranslucent with a reddish tint if recently fed

By the time they reach adulthood, bed bugs are approximately 5 – 6mm in length. Adult bed bugs can live for up to 12 months and lay about five to seven eggs per day.

Baby Bed Bug Bites vs. Adult Bed Bug Bites

When bed bugs bite, they inject saliva into the skin, which can cause allergic reactions. But everyone reacts to these bites differently. A study found that around 70% of people surveyed experienced psychological, health, social, and financial issues. This included skin irritation, insomnia, and poor concentration.

Nymphs generally have bites that are similar to those of adult bed bugs. Additionally, if an individual is allergic to bed bug bites, the saliva injected by a nymph will likely create the same reaction as an adult bed bug.

The appearance of the bite marks also varies depending on an individual’s reaction, but the size is consistent across all age groups of bed bugs. A bed bug bite is usually painless but can result in a red welt that may become swollen and itchy.

DID YOU KNOW?

A baby bed bug will change color from tan or translucent to a dark reddish-brown after it feeds on blood. They will also appear more swollen and elongated. 

How to Get Rid of Baby Bed Bugs

Getting rid of baby bugs is crucial. These pests can significantly damage your health, like the detrimental black bugs in your yard. Here are some suggestions for escaping the nasty infestations: 

  • Identify the infested area: Check your mattress, and other areas where bed bugs are known to hide. These can include cracks and crevices in walls, baseboards, and furniture.
  • Clean your home: Wash all pillows, bedding, and clothing in hot water and dry on high heat to kill any bed bugs. We also recommend vacuuming daily to remove any eggs or larvae.
  • Seal up openings: Seal all cracks and crevices in your home to stop bed bugs from entering or leaving. 
  • Use chemical treatments: Consider using a chemical treatment specifically designed to kill bed bugs. Be sure to follow all directions carefully and use the product as instructed. 
  • Use diatomaceous earth: This powder is composed of tiny fossilized algae and other particles that are sharp enough to cut through bed bug exoskeletons, dehydrating them. Purchase diatomaceous earth and sprinkle it around the baseboards, beneath furniture, or wherever else you suspect an infestation may be hiding. 
  • Hire a professional exterminator: If the infestation has become too severe, consider hiring a professional. They can safely and effectively eliminate pests and help prevent future infestations. 

These tips should help you get rid of baby bed bugs and keep your home safe from further infestations. Remember to practice proper hygiene and regularly check your home for signs of unwanted activity. With a bit of diligence, you can quickly eradicate these pests.

So, whether you are trying to eliminate a bed bug, identify insects that look like fleas, or keep your family safe from pests, it’s essential to be informed about the various types of bugs lurking around.
