I agree. Though it was a last resort after both lethal and non-lethal traps, repellent sprays and noise makers all failed. I was sick of seeing them skitter across the living room and dig in my vents all day

I've used a blend of cake mix, sprinkles and baking soda. I've been told they leave nests/house/walls/etc to seek water, which then expands and kills them. The gas then escapes, rendering it (probably) harmless to other animals
