Ace Exterminators

Ace Exterminators says it has been doing pest work for 39 years. Online, almost nobody has written about it. The Haverhill business, listed at 131 Hilldale Ave, carries exactly one customer rating — a 5 out of 5 from 2016 — and the Angi and HomeAdvisor pages showing it are the same listing rather than two independent opinions. Pest control and exterminating is the whole of what it advertises. So you have a long claimed history paired with a nearly blank public trail. The one rating on file is close to a decade old, which makes it a poor guide to how the company works today; ask for recent local references and get the scope and price of a treatment in writing before booking. Worth a call if you want a small, long-running Haverhill operator and you're willing to do the vetting yourself — there isn't a body of recent customer experience here to lean on.
