  1. We have chipmunks under our front brick steps and now we hear them Peking under the front door. There’s no holes so we don’t know what to use or do please any advice you can give us todo or try. Thank you

    1. Hello Muriel, Sorry for late reply.
      If you have chipmunks under the door, and it means, they have created tunnels under your house, and the openings or holes are somewhere else. You can try to locate these holes near your house, it can be in the neighbor’s garden or in the public park. Once you locate the holes, then place poison bait or chipmunk traps to kill them.
      If you are not able to find holes or you these methods on someone else’s property, then create a hole for them, and use bait or traps.
      Hope this helps.
