Oye, put a line of Salvo (yes, the dish detergent) around the hole from where they are coming. Make a full circle. Put a line anywhere you see a line of them, to disrupt the line.
You can also mix some with water in a spray bottle and spray it on them and it will kill on contact but be aware it will also kill other bugs so do NOT spray indeterminately and you should NOT spray your keyboard or other electronics. You can wipe those down.
