Mosquito Mayhem!

I have a serious question for all my dedicated readers, and it is this:

How come, when we live in the Western Cape, a winter rainfall area (hopefully more this year!), and we have not had rain for months and months now, how come we are plagued by mosquitoes? There is no water lying around at all, no puddles, no old paint tins filled with stagnant water waiting for mosquitoes to breed, no old sheep troughs lurking in gardens, nothing! I picture you nodding and thinking 'Ah yes, but they have bird baths, there's your answer!' No, we have to fill them at least four times a day, no time for a mosquito to land, let alone settle for a quick egg lay.

Now, when I say 'we' are plagued, I really mean Rob; he is plagued by them, and I am simply plagued by him trying to get rid of them from the bedroom in the middle of the night! He sprays that awful 'DOOM' in the bedroom during the evening when we are watching the T.V, and closes the door. That should do it. Just before we settle down for the night (in the dark so as not to have the light guiding them in), he sprays 'Peaceful Sleep' on him and I dab citronella oil on my head and arms and on the pillow. We even have a fan blowing on us to discourage landings!
That should do it! Right? Wrong!
