Chicken wire we erected around tree bases to prevent cats from scratching, touches lower branches in places that are above the grease that prevents climbing insects. Can these insects climb chicken/other wire - does anyone know for sure?
What a wonderful image of commando style insects you have conjured up for me.
You could always put a bit of grease on the chicken wire, just to be sure.
Ants (which 'farm' aphids) will find any way they can to get onto a tree - even a single stem of a tall grass. They use a 'carpet bombing' approach by wandering absolutely everywhere over time and any which find a way onto the tree and discover a suitable 'farming' site (usually the very youngest leaves) will leave a pheromone trail which the rest will soon follow..
Oh no! I guess that I'll have to find a way to keep the wire from touching the trees at any point. Many thanks for your advice & happy gardening????.
My question marks were actually a happy face!
