Your technician will determine what areas need to be treated at the time of service. We will address an active pest problem inside a crawlspace. Keep in mind that many pest problems are better handled from the outside. Interior treatment is not always necessary. If your crawlspace is a confined space, there will be restrictions on our ability to perform work inside of it. In our experience, it is not usually necessary to enter confined spaces. We will discuss options at the time of service, before treatment begins.
