Bed Bug Facts and Info

Life Cycle of a Bed Bug?

Bed bug infestation was common during the Second World War. After that, people believe that they were eradicated; however, these pests have made a comeback since the 1990s.

Today, having bed bugs is a common problem, especially in developing countries. Bed bug infestation can occur at any place such as college dormitories, prisons, hotels, and motels, shelters or apartments.

Many people think that they occur in dirty places, but it’s a wrong concept. You can find bed bugs in clean places as well. The bed bug is a tiny creature which is difficult to see at first glance.

Although bed bugs are small, they are still problematic. Their bites can irritate you, and if you are not so careful, you may spread them throughout your home. The bed bugs you have in your home may be in one of three stages of life: adult, nymph, and eggs.

Life Cycle of a Bed Bug

How Big Are Adult Bed Bugs?

  • The adult bed bug is the ultimate stage of their life cycle.
  • They will grow to reach the length of 6.5 mm long, making it visible to the naked eye.
  • Their size is approximately equal to an apple seed.
  • They even look like a seed with legs. They have a brown color with a flat, long and oval-shaped body.
  • They can change their body size when they are recently fed. Their color turns from brown to reddish brown after feeding.

Shape & Color Change?

  • They can live for a long time without feeding.
  • In right conditions, a bed bug can live on one feed for a few months or up to a year.
  • Their brown color turns to reddish after feeding the human blood.
  • If you take a vacation and they can’t hear for a while, conclude they metabolize their food slowly.

How Big Are Bed Bug Nymphs?

These are baby bed bugs that recently hatched from eggs and have not fed enough to grow into a full-size adult yet. It’s nearly impossible to see a nymph with a naked eye.

  • They are smaller than adult bed bugs, and their bodies are not brown yet.
  • They are translucent, which means that they can blend into their surroundings very well.
  • Nymphs only start to grow into adults when they have their first feed. However,  nymph doesn’t need to bite after their hatching. A nymph can wait for weeks or even months before it feeds for the first time.
  • Once they start to take feed get a bit of color in its body.
  • It may be slightly rounder in shape.
  • They are still hard to see for some time.
  • Nymphs need to feed three to five times before they can become an adult.

How Big Are Bed Bug Eggs?

The adult females laid their eggs and bed bugs hatched from these eggs. The eggs are nearly impossible to see unless they are right in front of your nose because they only stretch the size of a pinhead. The female bed bugs can only lay one to five eggs per day. Throughout their lifespan, a female can lay a total of 500 eggs. Their eggs are approximately 1 mm in length with white color. An egg will mark with a small eyespot after five days.

Can a Bed Bug’s Actual Size Change?

The average size of an adult bed bug ranges from ¼ to 3/16 of an inch in length. Their flat body looks significantly bigger after a blood feed. So, their size depends on their feeding habits, whether a bed bug is fed or not. After feeding, their bodies expand into a longer and more cylindrical shape.

How Can I Find Bed Bugs?

Because these pests are misidentified, the simplest way to find bed bugs is to call a bed bug professional.

  • Finding exoskeletons and shells of bed bugs
  • Bed bugs fecal stain in your bedding and mattresses

Differentiate Bed Bug from Other Insects

There are many bugs which look like bed bugs. You can discriminate them by their color and size. If you need to get rid of them, you must know the difference between bed bugs and other bugs.  Here is a list of some bugs which look like bed bugs.

Bat Bugs

Bat bugs are the most common pests found in homes before the re-emergence of bed bugs in the 1990s and 2000s. Bat bugs are more similar to bed bugs. Both bugs have a brown color, flat, and oval shape. They are also small in size, just like a bed bug. They typically live in a colony of bats. If you have bats in your wall, there is a high chance these insects live among them. Bat bugs also belong to the Cimicidae family of insects. They are most commonly found in roots and have the same look like bed bugs.

Swallow Bug

Swallow bugs are also a kind of parasites that live primarily among cliff swallows. They are less commonly present among barn swallows. Just like bed bugs and bat bugs, they are also small in size. They are flat, round, and brown. If swallows have made their nests on your home, you will surely find swallow bugs in your home.

Carpet Beetles

Carpet beetles are not from the family of bed bugs, but they are more similar to them. Carpet beetles have a segmented body just like bed bugs. Bed bugs have six legs while carpet beetles have eight legs. They have wings which differentiate them from the bed bugs.

Fleas

These are small and flat insects that can easily discriminate by flat hind legs used to jump great distance. They have small size as compared to bed bugs but have a segmented oval-shaped body like carpet beetles.

Wrap Up

You may think that bugs are bugs and all of them are gross, but you must be able to differentiate bed bugs and similar insects. Bed bugs do not cause to spread diseases; their bites are not so harmful. Their bites are not associated with other infestations, just like bats or birds. The bed bugs are living in a crowded area. However, flea bites are harmful and cause allergic reactions in some people. As a result, merely letting it go is not enough. You need to treat infestations properly.
