Hey guys,
Major problem... i noticed a few ants on my roof a few weeks ago and simply thought they would go away, Now this its getting hotted i see full trails of armies of ants crawling all over my roof, windscreen and bonnet and hiding in the cracks. I have not been able to figure out where the nest is centralized as they are all over my car and i know insect spray will damage my paint.

Any ideas on how to kill these pests off!?

PS. they are not inside my car yet although i have see 2-3 crawling on my dash.
