A HORMONAL SOLUTION to the bedbug problem:

When bedbugs mate, they do so by “traumatic insemination.” As the female lacks a genital opening, the male pierces her abdomen with his hypodermic genitalia to leave his sperm in her abdominal cavity. And because male bedbugs don’t discriminate between partners, they will climb on top of the nearest comrade — be it male or sexually immature. In these situations, they fatally wound the unsuspecting recipient of their amorous advances.

Luckily for bedbugs, nature has developed an alarm system to defend against unwanted embraces. When a male bedbug approaches a sexually immature nymph or male bedbug, the insect releases pheromones to let the male know he should find another friend.

Lovely creatures.
