Let me first say, going under a home is an adventure. Sometimes it can be an easy crawl… other times it can be your worst nightmare. But, when there is a Rodent Infestation, you have to go and inspect the area and address the problem.
In this particular scenario, Rats have been using a section under the house to both nest and use as their access point to exit the house and enter the house. There were rodent droppings all over and in general, a very active infestation.
To address this, we put traps out to get the Rats still under the house. As the second part of the plan, we excluded the open areas under the home and remove their point of entry/exit. We used a combination of materials and foam.
