I have Been growing outdoors for over 10yrs.
im in Australia.
The Only problem I have Is with Grass hoppers eating my Shade leaves.
But They dont effect the Plants growung in any way.
This Is gonna sound stupid But I have found Human Pee Keeps them away.
and also adds a boost of nitrogen into the soil..
but they always come back so i have learned to live with them.

you could try and find out what Plants the Bugs like to eat.
and Plant a few around your hooter.?.

I dont like to use poisons ill cut the leaves off with the bugs on before I'd poison..
