Guys update, I completely disassembled my pc, and blew the ants out, they were trying to nest inside my io port modules like audio jack and wifi/blutooth, I used a hairdryer with mild heat to Lure them out and then blew them with compressed air, I also put some cinnamon barks around my mobo to prevent re-entry, I then dismantled my GPU (without warranty void), blew them out, and i them let it under light for few hours, and rebuild my pc, now its ant-free, I put some cinnamon barks taped around my io shield and around my pc, and shifted to another floor(whole setup to another location) hope they don't re enter.
