A female bed bug’s vagina is never used in sex. How can that be? Traumatic insemination. When you’ve got a penis as hard and sharp as a knife, no vagina is necessary. Here’s what sex is like for a bed bug–

A female bed bug is stuffed after sucking blood from your sleeping body. She ate enough of your blood to be about 4 times fatter than she was earlier that afternoon.

Before the blood meal:

Now that she’s pleasantly plump, this lady looks pretty sexy to a male bed bug. No flirtation is necessary–a male climbs onto the female’s back. BAM! His penis stabs through the female’s belly and ejaculates. The sperm travel through the female’s blood, reach her oviducts, and fertilize her eggs. After a few minutes, the penis-stabbing mercifully stops.

The male doesn’t guard his mate. He just walks away after the deed is done. This leaves the female vulnerable to more sexual encounters.


A female bed bug can expect about 5 stab wounds after each meal. From 5 different males.

You can tell whether a female bed bug is a virgin by checking for scars on her stomach. Actually, you can see how many times a female has mated by counting her stab wounds. Not all the time, though. Sometimes the scars are too many to count.

from Siva-Jothy 2006 (Philosophical Transactions B)

Bed bugs densely populate your mattress, so a female encounters tons of male bed bugs no matter where she goes. A female bed bug has no control over her own sex life. Males impose themselves on her far more often than is practical. All this penis-stabbing into the abdomen is unhealthy for a female bed bug–too much or too clumsy sex is fatal. A female bed bug that survives needs to heal her stab wounds, and those wounds can become infected. One study[1] mentioned that “[r]ecently mated females were occasionally found dead with ruptured guts.”

Not to spread rumors[2], but male bed bugs often don’t discriminate between male and female partners. Regarding male-on-male events, some scientists speculate that the penis-stabbing male’s semen stays in the wounded male’s body, so the wounded male ejaculates his attacker’s semen when he finds his own partner to stab in the belly with his own genitalia. In other words, a bed bug doesn’t even need to stab a female in the stomach to get her pregnant; some other dude can do it for him.

Yes, bed bugs suck your blood, raise welts on your skin, and make you itch. Sure, bed bugs are persistent little bloodsuckers that can and will hide anywhere, making them almost impossible to eradicate. It’s true–bed bugs have wreaked their havoc from the hiding spot of one man’s prosthetic leg.

But here’s the silver lining–the happy ending to a bed bug story:
Bed bugs do not kill you. They don’t transmit any scary diseases.

Yeah, I know. That’s not enough for you to fall in love with them or stab them in the stomach (speaking figuratively) (and romantically). But you know you want to hug a bug!

[2] ^ Siva-Jothy (2006) dismissed the proposed evolutionary explanation for male-on-male bed bug sex as “an urban myth among zoologists”. In any event, here’s how entomologist and ecologist extraordinaire, May Berenbaum, has described apparent homosexuality in bed bugs: “With no elaborate courtship ritual, males in a frenzied pursuit of sexual congress often blunder into and puncture the bodies of other males, occasionally inflicting fatal wounds.”
