Ant over-running my garden plants/trees
By Fenclare
Alicante,
Spain 
I am having trouble with black ants in the garden! They persist in running up and down stems of my Bignonia, clematis and Orange tree. Spraying helps for a while but not long and I don't like using chemicals very much.
What can I do

You've probably got an aphid infestation in the plants, Fenclare - ants "herd" them to collect their honeydew, and that's why they're on the plants. Spray for aphids with a systemic insecticide (as long as you're not going to eat the oranges).

My neighbour puts black or chilli pepper on their mounds and then finishes off with boiling water.
I just leave mine be and its not a problem.
