I called Mike because I believed I had rats in the attic. He saw the droppings and confirmed the issue. He found some potential areas they were entering. Week one he set traps. Week 2 he cleaned out the traps , reset them, and sealed the potential entrances. Week 3 traps were removed and no more rat issues. The estimate was free and the total for his services was not much over $100 after my Yelp discount. Please support this honest mom and pop business.

Amazing service to start with, our office was over run with rodents, call their and spoke with a very nice representative, the technician Mr James was very impressionable, gave me a reasonable price, after the service, not only did he implement the rodents, he even was kind enough to remove the cob websof the front entrance , what a service, I highly recommend this service to anyone because of Mr James C , thank you for your 5 star service! !!!
