Checked bait stations in basement, garage, and on exterior of house. All bait in basement and on exterior was consumed. There was no activity in garage. I added a bait station on exterior near front entryway where I believe rodents are entering house. I refilled or replaced bait in all stations.I found some vole droppings in the basement that tell me that there is an entryway in your sill plate right by front door. Unfortunately due to the insulation against sill I was not able to find any holes. I suggest removing insulation at your convenience and filling any holes you find. I also suggest you call my office and have us back out in 2 weeks to check bait stations in basement to evaluate activity. Applied a residual liquid insect control to exterior perimeter, and a round doors and windows for ants and other insects. Please allow 2 weeks from when ant's first start crossing treatment to see full effect of insect control. Please call with any issues. Thank you.
