Michael: Yes; they prefer to attack after dark and they usually live only a few weeks during the warm summer months.
Vanessa: So… what? They find food and warmth in our houses?
Michael: Not only that! It’s also a place for them to lay their eggs.
Vanessa: How many eggs are we talking about?
Michael: A single female can lay over 200 eggs at a time.
Vanessa: Yuch!
Michael: . . . and they can survive for five years. Mind you – it’s only the females that bite.
Vanessa: In other words, the female mosquitoes are the blood suckers!?
Michael: Right!
Vanessa: So how can we tell male mosquitoes from female ones?
Michael: Research shows that females have smaller and less sensitive antennae than males but you certainly can’t tell the difference with the naked eye.

Vanessa: Is their buzz different at all?
Michael: Not that I know of; but it plays an important role in mating.
Vanessa: What do you mean?
Michael: In a nutshell, their eyesight is so poor that it’s the only way they can find each other. A female mosquito listens out for the buzz of a male and vice-versa.
Vanessa: So that annoying noise is the sound of mosquitoes flirting!
Michael: That’s it. And they continue until their buzzes are in harmony.
Vanessa: Amazing! Michael, thank you so much for being here!
