How to catch a mouse that avoids traps
Some mice learn to recognize traps as lethal, actively recoiling from them, moving them away from walls, or ignoring the bait entirely. Others manage to lick the bait clean without triggering the mechanism. This extreme avoidance can last for months, leaving people desperate and unable to clear the infestation.
