i have an infestation of these things in my plastic compost bin. i inherited this bin with my new site and i’ve continued to add to it. i put a lot of brussels sprout plants in the bin so i expect they like that. today in our first really warm weather there was a swarm of them on the plastic in the ‘shoulders’ of the bin.
as we are wanting to grow kale commercially on this site i’m quite horrified to see them. they are so tiny and difficult to catch in any way! are there any measures i can take to reduce them before kale season? google tells me to spray soap or garlic oil, i will try that but they are in among the compost so i will miss half of them whatever i do. should i burn the compost?
