Advice please regarding Aquilegia sawfly. Can anyone recommend an insecticide
that gets rid of them?

My local garden centre says a certain application for the lawn is the only
thing. This is seventeen pounds per packet.


Depends how many aquilegias you have. I have solomon's seal sawfly on
one clump: hold an old umbrella upside-down under the plant, shake the
grubs off, transfer to plastic bag, bin it.
