There is a difference between male vs female bed bugs, and this article will go into detail. However, only the female bed bug can lay eggs.
If you stay at a hotel and an adult female bed bug crawls into your suitcase, chances are it will lay eggs and start an infestation. The chances of bringing bed bugs home from a hotel are higher if you don’t take precautions.
The anatomy of each bug is similar to the untrained eye but different for a bed bug specialist. Male vs female bed bug: The female’s abdomen is round, whereas the male is pointier and with a notch. See the photos below. This is why we take the time to learn everything about bed bugs.
Both male and female bed bugs are flat oval-shaped brownish-red bugs depending on when they last had a blood meal. Bed bugs have piercing and sucking mouthparts on the ventral side of the head, and these piercing-sucking mouthparts are so they can feed on blood. More importantly, A female and male bed bug will only need blood to survive.
A male vs female bed bug: the female bed bug has different reproductive anatomy than the male bed bug. A female bed bug has evolved a paragenital system that helps the sperm move through her body cavity to its holding place. You can also see the sclerotized white scars on the ventral side of the female bed bug. These scars are usually on the right side of the female bed bug. The scars implicate the bed bug has become pregnant at one time or another by traumatic insemination.
Scientific Study on the Male VS Female Bed Bug
A scientific laboratory study found out that the male penetrates the right side of the female abdomen instead of the left. Even though the female bed bug has the same reproductive organs on the left side, traumatic insemination only happens on the right side. How did the scientists find this out? Well, they covered the right side of the abdomen, and those females remained unfertilized.
Then the scientists used artificial insemination on the left side of the female bed bugs, and they were able to become pregnant and lay eggs. So this allowed the scientists to know that both sides of the female bed bug work the same. The bed bug study also highlighted that male bed bugs have a preferred hand or handedness. Just like some people are right-handed or left-handed. The majority of the bed bugs chose the right side.

Can One Bed Bug Reproduce on its Own?
Yes, if it is an impregnated adult female because the female stores fertilized eggs, but bed bugs are not asexual. Learning the anatomy and physiology of a bed bug will you figure out if you have one of the bugs that are similar to a bed bug or if you indeed have an actual bed bug.
Are bed bugs asexual?
The answer is no. However, a female bed bug can lay eggs without a male present.
How Do Bed Bugs Reproduce? (Male vs female bed bug)
Bed bugs reproduce by a process called traumatic insemination. A male bed bug will pierce the female abdominal cuticle and inseminate directly into her body cavity. This piercing site is usually on the right side of the female bed bug body. Female bed bugs have a unique secondary genital system, called a paragenital tract. From here, the sperm move through the blood into the sperm storage organs; these are called the seminal conceptacles. Bed bugs have an open circulatory system. The blood and lymph circulate inside the body cavity unenclosed, which is the opposite of a mammal’s closed circulatory system. The sperm remains in this storage area until it migrates into the oviducts to fertilize the eggs.
According to the textbook Modern Bed Bugs by Dini Miller, Stephen Doggett, and Chow-Yang Lee, a female bed bug will have enough sperm stored in her seminal conceptacles to lay eggs for 35-50 days after sexual isolation. Since the offspring can interbreed, a single pregnant female can help start a new bed bug colony.
Do Bed Bugs Need a Mate to Reproduce?
Yes, you need a male and female bed bug to reproduce and start an infestation. However, you can pick up an adult female bed bug that has been impregnated and is ready to lay eggs. Males only mate with a recently fed female. Since bed bugs can mate with their offspring, the infestation can increase in size quickly after a few months. The bed bug nymphs cannot lay eggs, and the female bed bug will lay eggs between days 30 and 200 of her adult life.
Whether you find a male bed bug vs a female bed bug in your home, it’s essential to take some monitoring steps. If you search your entire bed, including the frame, and can’t find anymore, place some bed bug encasements on both your mattress and box spring, monitor your bed by searching every inch of it, and get a good steamer for bed bugs.
Are Bed Bug Bites Contagious?
A common myth is that bed bug bites are contagious; this is not true. Bed bugs are blood feeders, and there is no evidence to suggest they can transmit disease. If you have bed bug bites, it could be an allergic reaction or another type of irritation caused by the bite site. A person will not get bed bugs from being near someone else’s bites. However, bed bugs themselves are sometimes viewed as contagious because bed bugs are hitchhikers that can get on our clothing and get dropped off somewhere else.

In the common bed bug species, females typically develop a single spermalege on the right side of the abdomen. A spermalege is a unique organ where the female bed bug receives the sperm. When trying to ID a female bed bug vs a male bed bug, you will look for the rounded abdomen.
If you found a female bed bug, call a bed bug specialist company to do an inspection.
How to Tell if A Bed Bug is Pregnant?

Do Male Bed Bugs Bite?
Yes, male bed bugs bite. A bed bug is using the piercing-sucking mouthparts for drinking our blood, but they are not biting us with teeth. The stylets of bed bugs are thin, needlelike, and pierce our skin. A male bed bug, Cimex lectularius, takes between 5 and 20 minutes to fill up with a blood meal.
Can Male Bed Bugs Lay Eggs?
No male bed bugs do not lay eggs. This is where a male vs a female bed bug differs. A male bed bug is responsible for impregnating the female bed bug. A male bed bug deposits sperm through the female body cavity into the mesospermalege, where it remains for 4 hours before migrating through the bed bug’s hemolymph to the holding chamber.
Conclusion for Male vs Female Bed Bug
Female bed bugs will lay eggs without a male present. The female bed bug will receive the sperm through traumatic insemination, with most females storing enough sperm to fertilize eggs for 35-50 days after sexual isolation. Male vs female bed bugs bite with their mouthparts that cut into our skin and then insert the feeding tubes. If you find yourself looking at one pregnant female, this may start an entire infestation in your home.
