Imidacloprid is the active ingredient in a recently introduced insecticide
named 'Provado' in the UK. It was marketed under the slogan 'The last supper
for vine-weevils'. It also appears to be the last supper for just about
everything else. It effectively kills vine-weevil (adults and grubs),
lily-beetle (adults and grubs), greenfly, mealy-bugs, scale insects and just
about every other bulb-nasty. Some reports from other bulb growers are
saying that it is also an effective miticide and deals efficiently with
red-spider and even bulb-scale mite. It does not claim to be effective
against narcissus-fly grubs but I've not seen any further attacks on treated
bulbs since using it - even though I've frequently seen the fly out in
the garden. It is especially effective because one application (soaking the
compost) remains active for months. They have just introduced an aerosol
version under the name: 'The Ultimate Bug-Killer' primarily for indoor
The downside is that it is very expensive.

I endorse Tom and Jim's comments that it really works.
