Bedbug Life Cycle Pictures
This page features pictures and videos of bed bugs at each stage of the life cycle. A bed bug starts life as an egg and then
through 5 nymph stages (called Instars), culminating in adulthood. They are referred to as
until they reach adulthood.
A bed bug needs to feed at least once to move from stage to stage. Under ideal conditions/temperature, a bed bug will live for approximately 10 months. Each stage lasts from 4 to 24 days depending on the temperature and access to food. If all things are perfect the lifecycle takes about 5 weeks.

pictures of bed bug eggs
Bedbug eggs are laid in small clusters in groups of 2 or 3, and will average 3 to 5 eggs per day, but can lay up to 12. A female will lay approximately 500 eggs in her lifetime. A female must mate to lay eggs.
The eggs are yellow-white, 1mm in length (about the size of a sesame seed) and are oval shaped. It takes about 10 days before an egg will hatch.
Here's video of bed bug eggs and a bedbug hatching from an egg:

Here's a picture of bed bug eggs on a surface. Eggs are attached with a substance that firmly adheres them to the surface. This makes picking them up with a vacuum impossible. One approach is to pick them up with the sticky side of tape.
Killing bed bugs in a room requires killing the eggs as well. They can be killed with heat, such as from a hand steamer, and sprays that are labeled to kill bed bug eggs such as Bedlam.

bed bug nymphs (baby bed bugs)
Bed bug nymphs or baby bed bugs move through 5 stages after being hatched. They need to feed on a host and molt to move from stage to stage. Many people ask how long do bed bug nymphs live without food? (adults can live 12 to 14 months)
How Small Are Baby Bed Bugs?
Baby bed bugs are 1/16 in length.

adult bed bugs
As bed bugs become adults, they turn brown. After a blood meal,
they become reddish/brown in color.
Adult bed bugs are flat (1/16th of an inch) and approximately 1/4 to 3/8 of an inch in length (5mm to 9mm). They typically do not get larger than 1/4" in length.
Their small and flat profile makes it easy for them to hide in small space and fit through cracks in the walls and floors. Bed bugs are so small, that they have been found inside electronics, and between the glass and window frames. This is why when treating bed bugs, every inch of a room, including looking behind bed frames and pictures, is a required part of treatment.

How Often Do Bed bugs Feed?
Adult bed bugs will feed every 3 to 7 days depending on room temperature. Females cannot produce eggs wihtout feeding.
Bed Bug Size
Bed bugs do not get much larger than 7mm (1/4").

Another approach is to contact an exterminator through the Home Advisor network (or call 866-214-8380) who can confirm that you have an infestation. If you can capture an insect in a plastic pill jar or Ziploc bag.
National Geographic put together a helpful video on bed bugs and their
behavior. This is a good first step in learning how to identify bed

Survival and temparature
Bed bugs are killed in extreme heat and cold:
Heat: Killed at 120° F, or long exposure to 113° F
Cold: Can survive for a short time at 5° F, and can last for days at 32° F
Bed bugs can live for about a year without a blood meal1.
Bed Bugs in College Dorms or When
bugs in college dorms or picking them up when traveling is a common
problem. Given the transient nature of these institutions, people are
