Provision of habitat ... which *includes* trying to make sure I have all
of the links of the food chain. Therefore I've stopped using pesticides
(including molluscicides). And I know from observation that my
populations of greenfly are greatly appreciated ;-)

I have to admit that the only pesticide I use is a few slug pellets in
early spring. Don't seem to suffer much from greenfly as the tits eat
them and if the odd plant does become over infested, I just wash them
off with left over washing up water.
