Bill, Jane et al,

I rarely use sprays in my garden.  On rare ocassions I will use a systemic
such as Confidor when the aphid populations on the roses get too out of
hand.  Also the ocassional ant bait granules when a particular plant is
affected by the ants farming the aphids.  Other than that there is very
little needed.  I have sat at my computer looking out the window (which
seems to happen a lot for some reason ) watching the Fairy Wrens and
finches popping in and out of the garden.  They land on a branch and you
can see them looking carefully around them then they hop up to the rosebud
and start munching on the aphids.  They tend to keep them pretty much under

Snails and slugs on the other hand I do need to bait a couple of times a
year.  I find that a good application of snail bait in autumn really knocks
the stuffing out of them.  It was suggested to me a couple of years ago
that that killed them before they had a chance to lay eggs and go into
their dormancy.  Since applying bait in autumn I have only needed an
ocassional bait in spring when there is a wet spell.  I used to apply bait
numerous times in spring and never seemed to get ahead.  I'm mentioning
this here in case it helps others.  It certainly has cut down the snail
population in my garden and saved both money on baits and any chances of
damage to other plants an animals.

Also interesting to note.... I had been told that if you used Snail bait
then you would kill off any lizard populations in the garden.  We have a
healthy population of skinks and the ocassional Blue-Tongue so it seems
that the autumn method of baiting doesn't bother them as much.  There are
definitely more of them since I changed the schedule to autumn.
