I was recently sent to a job to inspect for Bed Bugs. Previous tenants had been treated for bed bugs and have moved out. Management wanted to know two things: How long has the unit been infested, and were there any live beg bugs. Inspection for bed bugs can be difficult as most units are full of furniture and belongings, this unit was vacant and empty.
The BedBug Life Cycle. Understanding the bedbug life cycle is vital if you want to get rid of bed bugs! Get quick facts about bed bug eggs, nymphs and adults; watch the video to see what they look like in real life; and learn what you need to know about all life stages to successfully identify and kill them.
Bed bug size changes at each life stage as shown below. A bed bug egg is 1/32" long. Adult bed bugs size that has not fed will be about 3/16". After feeding the body swells and grows in length to about 1/5" to 1/4".
During its lifetime, a bed bug will go through the following stages (Starting from the top left, moving counterclockwise): Eggs (1mm). 1st stage nymph (1.5 mm). 2nd stage nymph (2 mm). 3rd stage nymph (2.5 mm). 4th stage nymph (3 mm). 5th stage nymph (4.5 mm). Unfed adult female.
Adult bed bugs can reach a size of about 1/4 inch long. Nymphs range from 1.3 mm to 4-5 mm. Bed Bug Life Cycle Bed bug biology naturally promotes infestation.
Adult bedbugs have brownish, oval flat bodies about ¼-inch long. After feeding on animal or human blood, their bodies turn reddish and swell. They hide in crevices and cracks near a blood meal during the day and come out to feed at night.
