Our pack of 4 mouse traps are traditional wooden traps with a powerful spring mechanism. Suitable for indoor and outdoor use, it is ideal for controlling mice with paste-based baits like peanut butter or jam. Directions for use: Apply a food paste bait such as peanut butter to the bait pedal. Move the arm bar away from the bait pedal and hang it off the back of the trap. Firmly holding the platform pull up and over the kill bar away from the bait pedal and hold in position with your thumb. The kill bar should now be under tension. Move the arm bar to lock in place the kill bar, the kill bar is secured by hooking into the hole on the bait pedal. The trap is now set. Use multiple traps in severely affected areas. Mice live in groups and traps placed two-three meters apart will ensure the maximum catch. Block holes and passageways to force mice into the area where traps are sited. Protect traps in outdoor areas by placing them beneath the cover of a lean-to board.
