As I said above, they are brownish. But when they feed recently, their color changes a little bit. Bed bugs which have had recently are rounder, longer and darker.

A bed bug which has recently fed a lot can become even bright red, because of the color of the blood that it’s feed.

If bed bugs haven’t fed for a long time, they start to turn into yellow.

How long do they feed?

It depends on how hungry they are. But usually a bed bugs feed on a human for about 10 to 15 minutes and when they are done, they just go back to hide.

Bed bug eggs

Bed bugs multiply quickly which means after a bed bug infestation, you can see their eggs everywhere in the house. An adult female bed bug lay 2 to 5 eggs per a day which means 200 to 500 eggs for its lifetime.

Bed bug eggs are glued to every surface including the walls, cracks or beds. So, it’s really hard to remove them. If you have doubt about which insect left those eggs, so you can check it by measuring their stickiness.

Can bed bugs be seen with naked eye?

Answer to this question is yes for adult ones. Adult bed bugs are about an apple seed size. So you can see them around with naked eye.

Baby bed bugs can’t be seen with naked eyes for every situation. But it’s harder to see them when they are in the first stages of their growth. Baby bed bugs can be 5 times smaller than the adults.

It’s almost impossible to see baby bed bugs when they just hatch out of the egg if they do not move or recently fed.

How do bed bugs spread?

After locating in a house, it’s so easy to spread around for bed bugs. They first need hiding areas like cracks, holes or furniture which they can find easily.

After finding hiding areas, they start spreading by spawning. An adult female bed bug can lay 2 to 5 eggs per a day, so after only a few months, you can have hundreds of baby bed bugs at your home.

Other than this, bed bugs are resistant to hunger and they can live for several months. When spawning speed and their resistance come together, it’s not difficult to see how they spread quickly.
