to be attracted to the smell of DEET and associate it with feeding.

To explain this more, Medical Director of the Tropical Medical Bureau, Dr. Graeme Fry is with us.

Hello, Graeme.

Hi, John.

Now, the good news for me is that mosquitoes distinctly do not like me.

I don't know what it is about my blood.

They don't nibble on me at all, whereas my good lady wife is the equivalent of a Michelin-starred restaurant when they are nearby.

First of all, why do mosquitoes like some people more than others?

Now, people who go particularly to foreign climes, and I'm thinking Southeast Asia heading to places like Thailand, they will, as well as getting their all immunisations from their GP before they go, they tend to pack the deet because deet, we were always told, will keep the mosquitoes away.

So what has changed?

It's funny though, mosquitoes, I mean, they can be very, very serious.

And they obviously carry malaria, but they also carry other bugs as well.

Humans need to keep mosquitoes away from them as best they can.

And DEET has always been the best way of doing that.

I have seen mosquitoes in Ireland.

I've seen them in my house.

I've seen them around.

I mean, they're just kind of lazy that they don't want to nibble on us here.

Are conditions just not right for them?

Okay, so that's when you definitely need to do a little bit more.
