from "Megan Milligan" contains these words:

i recently tarted up my herb garden again after several months. does anyone
know of any good recipes for safe insecticides/repellents i can spray on
them to protect them but still be able to eat them when i want to?

Herbs don't need any protection against chewing or sucking insects,
they have their own. The aromatic oils which give the strong herb tastes
and smells are natural repellents, that's why people put dry herbs or
herb bags in linen cupboards and wardrobes.
