My boyfriend has some mint in a makeshift garden box on the ground on his driveway. It's just infront of a brick wall, so there's mint, and then a climbing plant going up the wall. The mint is being eaten from the inside of the leaf, and the climber is starting to show similar bite marks. We haven't seen anything but spiders around, and we haven't caught them on the plant at all.
The other one is neon pansies on a raised garden bed about a metre off the ground - Stu (boyfriend) did catch a caterpillar red handed over there.
My question is, is there anything we can do to get rid of these pests without spending heaps on chemicals at bunnings? Any info would be appreciated
