i disturbed a nest of ants in my veg plot under a brick which was holding down the netting over my brassica. There were hundreds of large eggs and the poor ants were desperately trying to move them to safety, within 10 minutes they had disappeared and I could not for the life of me have destroyed them. I have never come across any damage on my plot caused by ants. On the contrary I have seen them dispose of caterpillars, vine weevil and I am sure many more pests.
