Ok so first sunny day , decided to start on the garden jungle up until I saw the giant Ants literally around 3cms big 
their seems to be hundreds all busy doing their thing Anywho im guessing that their is a nest nearby gulp is their a way to tackle it at all 
I'm in the North West on the coast (UK) & my garden is humongous as it was part of a cemetery up until 1920 so I get all sorts of bugs
Would be grateful for any tips/advice
