Waltham Pest Services holds a 4.8-star average from 122 Google ratings, and its website lists a service area that runs from Groton and New London to Hartford, New Haven, Boston and Portland. A recent customer said Randy does not just do a standard treatment but takes the time to investigate the root cause of the problem, and shares advice on prevention. A recent customer described Randy Hall asking whether anything has changed, filling traps, then coming back to report problem areas. A recent customer said Randy Hall services their Dairy Queen in Groton, and a recent customer said he performs the pest services for Groton Public Schools. In a 2025 review, a customer said Billie had already left after treating their home and was about 45 minutes away when she turned around to look at something small that was not technically in their contract; she treated it, called to explain what she had done and sent video. In a 2023 review, a customer said Billie inspected the house for an NPMA 33 wood destroying organisms report needed for a VA loan, and also put on a bee suit and dusted a yellow jacket nest. A 2022 customer said the company called the morning after an online form and treated an underground yellowjacket nest, and that 2022 customer noted a 30 day guarantee. A 2025 customer with an ongoing service program at one restaurant said a one-time job at a different location was performed without the upfront quote they had asked for, followed by a $250 invoice they said they never authorized. That 2025 customer said attempts to contact the company were ignored or met with extremely delayed responses.
