Tansy will probably do the trick too
Tansy is one of those wild herbs that grows like crazy. Don't plant it in
the ground, it will take over

i was going to plant my little tansy seedlings all around the hen house, to
see if it helps with all the #!%&~! flies.

tbh i could think of worse things than it taking over - for example, the
flies taking over ;-)

(oh no! what if the tansy takes over, but it doesn't help at all with
keeping the flies away? ;-)
