How Big Are Bed Bugs
How big are bed bugs? Bedbugs are about 3/8 of an inch long. There are about the size of a lady beetle but much flatter. Now that is based on an adult. When they first start out as a nymphal stage bed they are about the size of a pin head. Now they go through several different stages. Each takes a blood meal to move on to the next stage. And each time they increase in size by about 25%. So by the time they hit the sixth floor adult stage they are readily observable. Now once a bedbug takes a blood meal hire to the adult stage they become quite round. So their size can vary depending on whether they have fed recently or not. The important thing to remember is that they start out very small. Progressively they grow larger in the course of about 6 to 8 weeks.
Their growth rate is dependent upon temperature, food availability, and general harborage and other environmental conditions. For example when the temperature is high 75 to 85° respiration increases, reproduction increases, feeding increases, and growth rates increase. So we can see that there environment is a lot to do with how big and how fast they get that way. Most people when they see an adult bed bug say that they look about the size of a tick. Other state they are closer in size to that of an Appleseed. The most important thing to remember is that they start out really small. Small enough that they can escape detection without the use of a good magnifying glass and a flashlight. By the time they reach adulthood they are more easily found but by this time they are probably reproducing and you are getting tiny little eggs laid all over your home or apartment. So remember that they are not invisible grab a flashlight and start looking.
