If you have a mole problem, this is the solution.  I've tried the peanut butter pellets that come in the cone, the fake tomcat worms, juicy fruit gum (what several "older" people told me to use) to no avail.  Put this trap in an active tunnel and BAM!, killed a huge mole the 1st day.  I've got 2 this year and am very pleased.  be careful when setting and installing, as the pan requires little pressure to set off.  And I flag mine so it's noticeable and I don't hit them with the mower.
