Tunneling critters under foundation
Our house was built in 1910. It was constructed on brick pillars which extend at least a foot underneath the ground. Some time in the past 40 years, a previous owner filled in the gaps between the pillars with cement block and painted the whole foundation to make it look cohesive. The cement block sits directly on top of the ground.
A couple of weeks ago we noticed tunnels going underneath the cement block portions of the foundation. Then, something obviously died in one of our walls---what a smell!
We called our pest control company. They determined that in order to keep the rats or chipmunks from tunneling under the cement block, a trench one foot wide and one foot deep under the ground level would have to be dug around the entire perimeter of the house and filled with cement. In addition, we are going to have an entire house exclusion done to fill in any access areas other than the foundation. They are also setting numerous traps to eliminate any existing rodents.
My question to all of you old house owners is, Have any of you had this cement trench done and, most important, did it stop critters from tunneling under your foundation?
