Cynthia from First Illinois has been working at our place of business for many years now. Any time a pest has been spotted she has arrived within hours to investigate and treat. We used to have a different company that would arrive late if they came at all without a second follow up call. Cynthia is very knowledgeable always providing valuable information to prevent pest in the future instead of just putting a treatment and leaving. I would recommend them to anyone in need of this service.Services: General pest inspection

We have used First Illinois for their integrated pest management approach for the past almost five years.

I can recommend them without qualification.

You have to have an exterminator on board even if you rarely have problems, and this is the one to use.
