If you end up with a substantial pest infestation, it will likely be more practical to hire a professional rather than trying to exterminate them yourself. This is especially true if your problem has been ongoing, the infestation is widespread, or if you need products that are only certified for use by professionals.

Credentials

Before any company starts working on your pest problem, ask to see their certification, license, and ID. Make sure all documents are authentic and current so that you know they have the proper training and authorization.
