How to set effective mouse snap traps?
Follow these 3 rules of mouse trapping: 1) always in pairs, 2 )baited and 3) place along rodent runways, usually edges.
1) Always place mouse traps in pairs unless there is no room. When the mouse jumps the first trap it will caught in the second.
2) Place bait in the bait tray, visible here just in front of the hinge on the yellow trigger.
3) Place traps with the trigger (the yellow or metal on Victor traps) against the edge of the wall or runway. Rodent use their vibrissae or whiskers to feel along edges and traps placed against an edge are much more attractive.
