Were up to about 6 now. I think I found the entrance point (a big tube to the back deck that used to be hooked up to a dryer in the basement), thing is clogged now. We set a bunch of traps up in the basement ceiling panels and under the kitchen sink (where the droppings were). Earlier this evening I heard a loud snap and when I go to check it out there's a big fat one still struggling with it's face in a trap. I crushed the damn thing with a Swedish walking pole cause it seemed like a faster death. I sincerely hope that was the last one. It stinks like shit under the kitchen sink, if anyone is going to destroy my property value it will be me. Iv never killed anything larger than a fly before... It was unpleasant yet justified. Nevertheless these pests must die!
