The present invention relates to an improvement in rodent traps which allows traps to be pre-set and pre-baited during manufacture, placed in an appropriate housing and discarded after use. The trap consists of an essentially traditional spring biased killing jaw with a novel retaining device and release trigger. A retaining cord holds the jaw in a loaded position and is disposed to release the jaw when the cord is severed by being chewed by a rodent eating the bait which is impregnated into the cord at a point along its length between tie-down points.
