Time to go down to Coles and grab a sixpack of those insect bombs. Throw one each in the observatory, shed, garage, outhouse, roofspace of your house and under the floor.
Do it all at the same time so you get all the breeders and all the eggs together. I highly reccomend surface spray around every door, window, cornice and skirt too. Petrol down the holes of the big ants nests and sump-oil all along the bottom of your boundary fences. NUKE EM ALL I say!
Trees....cut them all down, they spoil the view.
If I want to see nature, I go out of the city. Nature should stay out of the suburbs.....unless it helps pay the rent....
