We have two bushes front and back with dark green spiky leaves that produce masses of blue berries at this time of the year.
Birds eat them and then proceed to excrete purple droppings. They can ruin a carpet if it gets inside the house.
I want to fit deterents to my gutters in the direct line of fire.
I see spikes advertised but no indication as to how they are affixed.
Does anyone have any suggestions?
